Description

Technical Field

[0001] The present invention relates to the field of monitoring technology, and in particular to a camera. Background Art

[0002] There are many types of cameras available on the market. One type of surveillance camera supports both pan and tilt, also known as a PT camera. PT cameras are suitable for use in large surveillance areas and for scenes where details within the field of view are of interest. If details are important, the PT camera's lens needs to be frequently rotated. Because both pan and tilt rotation of a PT camera's lens require separate motor drives, and in most cases, the structure of a PT camera is complex, requiring a reasonable layout and complex transmission to connect a single lens to both a pan and tilt motor, this further complicates the structure and increases the size of the PT camera. Therefore, it is necessary to propose an improved camera. Summary of the Invention

[0017] In order to solve the technical problem that the structure of PT cameras is more complicated and causes the size of PT cameras to be large, the present application provides a camera including an outer shell and a main body shell, a first lens assembly, a reflector assembly, a fill light assembly and a radar module. The outer shell includes a shell body and a front cover, the front cover covers the front side of the shell body, the main body shell is accommodated in the outer shell, and the front cover is provided with a first through hole. The first lens assembly and the reflector assembly are respectively arranged in the main body shell, and the former includes a first lens, which is configured to receive light in the monitoring area passing through the first through hole, and the latter is located on the optical path of the light in the monitoring area incident on the first lens assembly. The reflector assembly includes a reflector arranged corresponding to the first through hole, which is configured to reflect the light in the monitoring area incident through the first through hole to the first lens assembly. The first lens is located on one side of the first through hole in the second direction. The fill light assembly is arranged in the front cover. The radar module is assembled below the shell body. The radar module includes a longitudinally extending radome and a radar board disposed within the radome. The hollow cavity formed by the radome has a smaller dimension in a second direction than in a first direction perpendicular to the second direction. The radar board faces the front of the radome, and the hollow cavity enclosed by the radome and the hollow cavity enclosed by the housing do not share a common cavity. The camera is configured to trigger the fill light assembly to illuminate and / or trigger the first lens assembly to capture an image when the radar module detects a monitored object entering the monitoring area. The reflector assembly is positioned within the optical path of light incident on the first lens assembly, eliminating the need for horizontal rotation of the first lens assembly itself. The reflector assembly can be rotated horizontally, reflecting light from the reflector to present an image of the monitored area to the first lens assembly. The fill light assembly is disposed within the front cover, resulting in a simple overall structure and compact size. At the same time, the above-mentioned radar module is assembled under the shell body. The hollow cavity surrounded by the radar cover and the hollow cavity surrounded by the shell body do not share the same cavity, which makes the volume of the front cover and its decorative parts smaller, the structural design of the front cover simpler, the mold cost for parts production is reduced, and the cost of the whole machine is reduced. It also facilitates the layout of other modules on the front cover.

[0018] Figure 1 FIG. 1 is a perspective schematic diagram of a camera 10 according to an embodiment of the present application. Figure 2 FIG. 1 is a front view of a camera 10 according to an embodiment of the present application. Figure 3 Shown Figure 1 FIG. 1 is an exploded view of the camera 10. Figure 1 and Figure 2As shown, the camera 10 of the embodiment of the present application may include but is not limited to a housing assembly 11, and a host 12 respectively housed inside the housing assembly 11. The host 12 includes a first lens assembly 13, a second lens assembly 14 and a reflector assembly 15. The second lens assembly 14 is used to capture images of the monitored area and can be referred to as a panoramic lens assembly. The first lens assembly 13 is used to capture details or magnify the images captured by the second lens assembly 14 and can be referred to as a detail lens assembly. The reflector assembly 15 is located on the optical path of light incident on the first lens assembly 13 and is used to reflect the light to the first lens assembly 13. In this way, imaging can be achieved by reflecting the light from the reflector assembly 15.

[0019] The field of view of the first lens assembly 13 is smaller than that of the second lens assembly 14. In this way, the range of the monitoring area photographed by the second lens assembly 14 covers the range of the monitoring area photographed by the first lens assembly 13, so that the image photographed by the second lens assembly 14 can be magnified in detail. The above-mentioned first lens assembly 13 includes a first lens 132, which can be tilted and rotated. The reflector assembly 15 can be rotated horizontally. The second lens assembly 14 is immovable, and detailed description is given below. Figure 2 As shown, the orthographic projections of the optical axis 141 of the second lens assembly 14 and the optical axis 131 of the first lens assembly 13 on a horizontal plane are perpendicular to each other. Thus, when the first lens assembly 13 is in a horizontal position, the first lens assembly 13 and the second lens assembly 14 can minimize the size of the camera 10 in the first direction W and the vertical direction. The first direction W can be the left-right direction.

[0020] Combine Figures 1 to 3 As shown, the housing assembly 11 includes a front cover 16, which is used to cover the outside of the main body 12, protecting the main body 12 and facilitating light entry for image capture. The front cover 16 is provided with a first through-hole 161 and a second through-hole 162. The first through-hole 161 is configured to allow light to enter the first lens assembly 13 and can be referred to as a first window. The second through-hole 162 corresponds to the second lens assembly 14 and is configured to allow light to enter the second lens assembly 14 and can be referred to as a second window. The first through-hole 161 is located above the second through-hole 162. The vertical arrangement of the first through-hole 161 and the second through-hole 162 positions the first lens assembly 13 above the second lens assembly 14, and the area of ​​the first through-hole 161 is larger than that of the second through-hole 162. The area of ​​the first through-hole 161 is determined by the reflector and the first lens assembly 13, while the area of ​​the second through-hole 162 is determined by the second lens assembly 14.

[0021] The vertical dimension of the first through hole 161 is larger than the vertical dimension of the second through hole 162, and the horizontal dimension of the first through hole 161 is equal to or larger than the horizontal dimension of the second through hole 162. In this way, the area of ​​the first through hole 161 receiving light is larger than the area of ​​the second through hole 162 receiving light, which is more conducive to the light incident on the reflector assembly 15. In addition, the second through hole 162 is smaller than the first through hole 161, which is also conducive to the miniaturization of the device. Figure 2 As shown, reflector assembly 15 is positioned along the optical path of light incident on first lens assembly 13, thereby expanding the visible area. Reflector assembly 15 includes reflector 151. Reflector 151 is positioned corresponding to first through-hole 161 and is configured to reflect light incident through first through-hole 161 back toward first lens assembly 13. In this way, first lens assembly 13 and second lens assembly 14 achieve dual-lens image capture, with reflector 151 allowing light to enter first lens assembly 13, expanding the visible area, and maintaining a simple structure.

[0022] Furthermore, the first lens 132 and the reflector 151 are respectively arranged in the first through hole 161, the reflector 151 extends longitudinally, and the first lens 132 faces the reflector 151. In this way, the reflector 151 extends vertically, which is conducive to the light being incident on the first lens 132 when the reflector 151 rotates horizontally. In addition, the first lens 132 can be pitched, thereby realizing horizontal shooting and pitch shooting of the first lens assembly 13. Among them, the reflector 151 can be rectangular. Compared with a circular reflector 151, a rectangular reflector 151 saves space and cost. For example, the rectangle can be a rectangle. The long side of the reflector 151 can extend horizontally, and the short side of the reflector 151 can extend longitudinally (vertically). For another example, the rectangle can be a square.

[0023] Figure 4 Shown Figure 1 The figure shows a perspective diagram of the reflector assembly and the first lens assembly 13 in the camera 10. Figure 5 Shown Figure 1 The front view of the reflector assembly and the first lens assembly 13 of the camera 10 is shown. Figures 4 and 5As shown, the reflector assembly 15 also includes a horizontal rotation structure connected to the reflector 151. The horizontal rotation structure is configured to drive the reflector 151 to rotate horizontally to achieve horizontal rotation of the reflector 151. The horizontal rotation structure may include, but is not limited to, a horizontal rotation motor 21. The horizontal rotation motor 21 is connected to the reflector 151 and is used to drive the reflector 151 to rotate horizontally. The horizontal rotation motor 21 and the second lens assembly 14 are located below the reflector 151, so that the horizontal rotation motor 21 and the second lens assembly 14 are located on the same side of the reflector 151 in the vertical direction. When the horizontal rotation motor 21 rotates, it drives the reflector 151 to rotate horizontally. In this way, the first lens assembly 13 itself does not need to rotate horizontally, and the reflector assembly 15 can achieve horizontal rotation. Through the reflection of light from the reflector 151, the image of the monitored area is presented on the first lens assembly 13.

[0024] continue Figure 5 As shown, the horizontal rotation motor 21 can be a direct drive motor. In this way, the motor shaft 211 of the horizontal rotation motor 21 is directly connected to the rotating shaft 157 of the reflector assembly 15, and there are no other transmission parts between the two. In this way, the horizontal rotation motor 21 acts as a power source, directly driving the reflector assembly 15 to be driven to move, reducing the transmission of other transmission parts, saving costs, and facilitating the miniaturization of the structure. At the same time, the horizontal movement of the reflector 151 is achieved, effectively increasing the monitoring range of the camera 10. Figure 5 As shown, the reflector 151 includes a first side 153 and a second side 154 that are opposite to each other in a first direction W. The first lens 132 is located on the second side 154, facing the reflector 151. The rotation axis 157 of the reflector 151 deviates from the center 1512 of the reflective surface 1511 of the reflector 151 and is closer to the second side 154 relative to the first side 153. In this way, the second side 154 of the reflector 151 is close to the first lens 132, and the image distortion is small. In addition, the first side 153 of the reflector 151 is far from the first lens 132, and the range that can be photographed is wider. At the same time, the rotation axis 157 of the reflector 151 deviates from the center 1512 of the reflective surface 1511 of the reflector 151. Compared with the range of the reflector 151 with a symmetrical rotation axis structure, the second side 154 of the reflector 151 is shorter from the rotation axis 157 and occupies a smaller volume.

[0025] Figure 6 Shown Figure 4 The reflector 151 and the first lens assembly 13 are shown along Figure 4 Cross-sectional view along line BB. Figure 7 Shown Figure 4 The front view of the reflector 151 and the first lens 132 is shown. Figure 6 and Figure 7As shown, the reflector 151 includes a first horizontal boundary position 155 and a second horizontal boundary position 156. The reflector 151 rotates horizontally between the first horizontal boundary position 155 and the second horizontal boundary position 156. When the reflector 151 rotates from the first horizontal boundary position 155 to the second horizontal boundary position 156 and the first lens 132 remains stationary, the horizontal intersection trajectory 22 of the optical axis 131 of the first lens 132 and the reflector 151 deviates from the center 1512 of the reflective surface 1511 of the reflector 151. In this way, the horizontal intersection trajectory 22 of the optical axis 131 of the first lens 132 and the reflector 151 are not collinear with the center 1512 of the reflective surface 1511 of the reflector 151, thereby enabling the first lens assembly 13 to rotate horizontally to capture images of the monitored area and also achieving miniaturization of the camera 10. Figure 6 The first horizontal boundary position 155 and the second horizontal boundary position 156 are merely examples, and do not limit the specific positions of the first horizontal boundary position 155 and the second horizontal boundary position 156 .

[0026] like Figure 6 and Figure 7 As shown, the reflector 151 is set at an initial position, for example, when the angle v between the extension line of the reflective surface 1511 of the reflector 151 and the extended mirror surface of the first lens 132 when the first lens 132 is in the first direction W is 45 degrees. The rotation angle of the reflector 151 in this initial position can be referred to as the horizontal rotation angle. When the reflector 151 is rotated horizontally in a direction away from the first horizontal boundary position 155 of the first lens 132, the horizontal rotation angle can be a negative value. When the reflector is rotated horizontally in a direction toward the second horizontal boundary position 156 of the first lens 132, the horizontal rotation angle can be a positive value. The horizontal rotation angle can range from greater than -15 degrees to less than +15 degrees.

[0027] Continue as Figure 6 and Figure 7 As shown, the horizontal movement of the reflector 151 and the vertical movement of the first lens assembly 13 achieve image field angle coverage, where the image field angle coverage includes the horizontal field angle and the vertical field angle. In this way, the second lens assembly 14 detects the human body and links the first lens assembly 13 to capture the image. It is necessary to ensure that the field angle of the first lens assembly 13 overlaps the field angle of the second lens assembly 14 through the PT movement.

[0028] The horizontal movement of the reflector 151 is achieved by direct motor drive, and the range of motion is ±c. The horizontal field of view that the reflector 151 can cover as a whole is: D = c 2+b h , D≥a h , to meet the demand, where a h is the horizontal field angle of the second lens assembly 14, b hIt is the horizontal field of view angle of the first lens assembly 13, and the field of view angle of the second lens assembly 14 is greater than the field of view angle of the first lens assembly 13. The rotation axis 157 of the reflector 151 is on the same horizontal plane as the optical axis 131 of the first lens assembly 13, and the closer the distance L between the two is, the better. However, in order to avoid interference between the reflector 151 and the first lens assembly 13 and affect the rotation, the distance L is at least greater than zero. In this way, light can be incident through the light incident range 158 of the reflector 151. Since the reflecting surface 1511 of the reflector 151 will not be rotated to the back or completely perpendicular to the first lens 132, at least part of the light is incident on the light incident range 158 of the reflector 151, as shown in FIG. Figure 6 An ellipse is shown in the light incidence range 158 .

[0029] Continue as Figure 6 and Figure 7 As shown, the vertical field angle that the first lens assembly 13 can cover as a whole is F =e 2+b v , F≥a v , meeting the demand, where a v is the vertical field angle of the second lens assembly 14, b v is the vertical field of view of the first lens assembly 13, and e is the range of vertical motion of the first lens assembly 13 achieved by direct drive. In this way, the full field of view angle is covered by controlling the horizontal rotation of the reflector 151 and the vertical motion of the first lens 132.

[0030] like Figure 7 As shown, the first lens 132 includes a first pitch boundary position 133 and a second pitch boundary position 134. The first lens 132 pitches and rotates between the first pitch boundary position 133 and the second pitch boundary position 134. When the first lens 132 rotates from the first pitch boundary position 133 to the second pitch boundary position 134 and the reflector 151 remains stationary, the pitch intersection trajectory 23 between the optical axis 131 of the first lens 132 and the reflector 151 deviates from the center 1512 of the reflective surface 1511 of the reflector 151. In this way, the pitch intersection trajectory 23 between the optical axis 131 of the first lens 132 and the reflector 151 is not collinear with the center 1512 of the reflective surface 1511 of the reflector 151, enabling the first lens assembly 13 to pitch and rotate to capture images of the monitored area, thereby achieving miniaturization of the camera 10. Figure 7 The first pitch boundary position 133 and the second pitch boundary position 134 are merely examples, and do not limit the specific positions of the first pitch boundary position 133 and the second pitch boundary position 134 .

[0031] Figure 8 FIG. 1 is a schematic diagram showing a first viewing angle of the reflector 151 and the first window glass 1613 . Figure 9FIG. 1 is a schematic diagram showing a second viewing angle of the reflector 151 and the first window glass 1613. Figure 8 and Figure 9 As shown, the first through hole 161 is provided with a first window glass 1613. The first window glass 1613 can seal the reflector 151 and the first lens 132 to protect the reflector 151 and the first lens 132. The closer the distance between the rotating shaft 157 of the reflector 151 and the first window glass 1613 is, the better, to meet the viewing angle and image without black edges.

[0032] Combine Figure 3 As shown, the housing assembly 11 includes an outer shell 17 and a main body housing 18. The outer shell 17 includes a shell body 19 and a front cover 16. The front cover 16 covers the front side of the shell body 19. The main body housing 18 is accommodated in the outer shell 17. The front cover 16 covers the front side of the main body housing 18. The reflector 151 is accommodated in the main body housing 18. The first lens assembly 13 is arranged in the shell body 19. The front cover 16 is provided with a first through hole 161. In this way, horizontal movement and vertical movement are highly integrated into a main body housing 18. The overall shape of the camera 10 can be effectively reduced, the whole machine is easy to install and assemble, and the whole machine cost is low. In some embodiments, the housing assembly 11 also includes a sunshade 20, which is provided on the top of the outer shell 17 and the main body housing 18 to block the sun.

[0033] Continue to combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the main body housing 18 includes an opening 182. Opening 182 faces the first through-hole 161. A reflector 151 is disposed within the main body housing 18, corresponding to the first through-hole 161. The reflector 151 is positioned near the first cover sidewall 166 relative to the second cover sidewall 164. The opening 182 accommodates the reflector 151 and the first lens 132 and can communicate with the first through-hole 161 to allow light to enter.

[0034] Figure 10 Shown Figure 4 The host shown is along with the host housing 18 Figure 4 The cross-sectional view of the AA line in FIG. Figure 10As shown, the reflector assembly 15 includes a reflector mounting frame 152 for supporting a reflector 151. The reflector 151 is fixed to the reflector mounting frame 152. The reflector mounting frame 152 includes a motor connecting end 1521 and a rotatable end 1522. The motor connecting end 1521 is located on the lower side of the reflector 151 and is connected to the horizontal rotation motor 21. The horizontal rotation motor 21 is used to drive the motor connecting end 1521 of the reflector 151 to rotate. The rotatable end 1522 is located on the upper side of the reflector 151 and is rotatably connected to the main body housing 18 to drive the reflector 151 to rotate horizontally. In this way, the motor connecting end 1521 and the rotatable end 1522 are located on the upper and lower sides of the reflector mounting frame 152, which facilitates the horizontal rotation of the reflector assembly 15 and also facilitates the staggered arrangement of the horizontal rotation motor 21 of the reflector assembly 15 with other components, thereby achieving miniaturization of the camera 10.

[0035] Figure 11 Shown Figure 4 An exploded schematic diagram of the host and the host housing 18 is shown. Figure 12 Shown Figure 10 The local enlarged schematic diagram of D is shown in FIG. Figure 11 and Figure 12 As shown, the reflector assembly 15 includes a horizontal bearing 24. The horizontal bearing 24 rotates horizontally along with the reflector 151 as the horizontal rotation motor 21 rotates, reducing friction during horizontal rotation and facilitating horizontal rotation of the reflector 151. The horizontal bearing 24 is disposed between the rotatable end 1522 and the main body housing 18. The rotatable end 1522 rotates horizontally relative to the main body housing 18 via the horizontal bearing 24. In this manner, the reflector 151 is supported from above by the horizontal bearing 24 and directly connected and supported from below by the horizontal rotation motor 21, driving the reflector assembly 15 to achieve horizontal motion. This provides excellent overall structural stability, direct power transmission, and high transmission efficiency. Furthermore, the horizontal bearing 24 and the horizontal rotation motor 21 are respectively disposed on the upper and lower sides of the reflector mounting frame 152, reducing the space required for centralized installation and facilitating a reduction in the overall size of the camera 10.

[0036] like Figure 11As shown, the reflector mounting bracket 152 includes a front bracket 31 and a rear bracket 32 ​​connected to the rear side of the front bracket 31. The reflector 151 is clamped between the front bracket 31 and the rear bracket 32. The front bracket 31 and the rear bracket 32 ​​protect and support the reflector 151. The front bracket 31 includes an annular front clamping portion 311, and the rear bracket 32 ​​includes an annular rear clamping portion 321. The reflector assembly 15 includes a mounting buffer 33. The mounting buffer 33 surrounds the side of the reflector 151 and is clamped between the reflector 151 and the front clamping portion 311. The rear clamping portion 321 surrounds the outer side of the front clamping portion 311 and presses against the front clamping portion 311. In this way, the reflector 151 is squeezed and installed between the front bracket 31 and the rear bracket 32 ​​through the rear clamping portion 321, and the installation buffer 33 surrounds the side of the reflector 151 and is clamped between the reflector 151 and the front clamping portion 311. The reflector 151 is squeezed by the compression deformation of the installation buffer 33, so that the reflector 151 is safely and reliably fixed.

[0037] The mounting buffer 33 is compressible and deformable. It can be, but is not limited to, a rubber sleeve in an annular shape. The sleeve is positioned over the side of the reflector 151, leaving a gap for light reflected from the reflective surface 1511 of the reflector 151. This prevents the rigid connection between the front and rear brackets 31, 32, and the reflector 151 from affecting the reflector 151, while maintaining a secure and protective position.

[0038] continue Figure 11 As shown, the reflector assembly 15 further includes a buffer pad 34. The buffer pad 34 is sandwiched between the rear side of the rear bracket 32 ​​and the fastener 35 to securely connect the reflector mounting frame 152 via the rear bracket 32, thereby improving the stability of the fixation. The fastener 35 may be a screw. The buffer pad 34 may be an elastic gasket or a metal gasket, which will not be listed here. Figure 11 As shown, the horizontal rotation motor 21 for driving the reflector assembly 15 to rotate horizontally is mounted on the motor mounting bracket 28 through four screws to form an assembly.

[0039] The installation process of the above-mentioned installation buffer 33 and buffer pad 34 is as follows: first, put the installation buffer 33 on the side of the reflector 151. Since the installation buffer 33 has a low hardness, it can be compressed and deformed. Then place the reflector 151 on the front bracket 31 of the reflector 151. The reflector 151 is squeezed and installed between the front bracket 31 and the rear bracket 32 ​​of the reflector 151 through the rear bracket 32 ​​of the reflector 151. Since the installation buffer 33 has a low hardness and can be compressed and deformed, it can avoid the reflector 151 from directly contacting the structural parts and avoid manufacturing errors of parts, which may cause the reflector 151 to be crushed. The reflector 151 installation rubber sleeve plays both an installation and a protective role. Finally, the buffer pad 34 is installed on the rear bracket 32 ​​of the reflector 151 by screws. When the product is not powered on and there is no motor drive, it can effectively play a buffering role and effectively prevent the reflector 151 from being damaged by vibration, as shown below Figure 14 The front side of the reflector 151 and Figure 15 The back side of the reflecting mirror 151 is shown.

[0040] Continue as Figure 11 and Figure 12 As shown, the camera 10 further includes a horizontal photoelectric panel 26 and a horizontal photoelectric baffle 27. The horizontal photoelectric panel 26 can detect the rotation angle of the reflector mounting frame 152. The horizontal photoelectric baffle 27 can limit the longitudinal displacement of the horizontal photoelectric panel 26. The horizontal photoelectric panel 26 is sandwiched between the rotatable end 1522 and the horizontal photoelectric baffle 27, and the horizontal photoelectric baffle 27 is fixedly connected to the rotatable end 1522. The horizontal rotation motor 21 and the second lens assembly 14 are located on the same side of the reflector 151 in the vertical direction. In this way, the horizontal photoelectric baffle 27 and the horizontal photoelectric panel 26 rotate together with the rotatable end 1522 to detect the rotation angle of the reflector mounting frame 152.

[0041] The rotatable end 1522 of the reflector mounting bracket 152 corresponding to the horizontal photoelectric panel 26 has an initial position. This horizontal photoelectric panel 26, in conjunction with a photoelectric switch (not shown), can be rotated to a specific angle. The photoelectric switch rotates according to a specific angle, such as 15°, 30°, or 45°. The photoelectric switch has a transmitting end and a receiving end. When the horizontal photoelectric panel 26 rotates to the corresponding photoelectric switch, it blocks light from the transmitting end to the receiving end, thereby recording the position of the rotatable end 1522 and the rotation angle.

[0042] The fixing member 29 is arranged parallel to the axis of the horizontal photoelectric baffle 27 and the horizontal photoelectric panel 26, passing through the horizontal photoelectric baffle 27 and the horizontal photoelectric panel 26 and connected to the rotatable end 1522. This allows the horizontal photoelectric panel 26 and the horizontal photoelectric baffle 27 to rotate together with the reflector mounting bracket 152. Furthermore, the fixing member 29 may include a screw. The rotatable end 1522 may include a table-shaped end surface. This table-shaped end surface may be truncated. A threaded hole is defined along the axial direction of the table-shaped end surface, and the screws are sequentially passed through the horizontal photoelectric baffle 27 and the horizontal photoelectric panel 26 and connected to the threaded hole.

[0043] Continue as Figures 10 to 12 As shown, the motor connection end 1521 and the rotatable end 1522 are provided on the rear bracket 32, and protrude forward from the rear bracket 32 ​​to extend to the bottom of the front bracket 31 and the reflector 151. The motor connection end 1521 and the rotatable end 1522 provided in this way can not only realize the connection, but also provide a certain support for the reflector 151, thereby improving the stability of the connection of the reflector 151 and further improving the stability of the rotation of the reflector 151. Figure 11 and Figure 12 As shown, the reflector assembly 15 further includes a horizontal bearing baffle 25 connected to the rear bracket 32 ​​of the reflector mounting frame 152 , and the horizontal bearing 24 is sandwiched between the horizontal bearing baffle 25 and the main body housing 18 .

[0044] The installation process of the horizontal photoelectric baffle 27, horizontal photoelectric panel 26, horizontal bearing baffle 25, and horizontal bearing 24 is as follows: the horizontal bearing 24 is fixed to the main body housing 18 via the horizontal bearing baffle 25. The reflector assembly 15 is connected to the horizontal rotation motor 21 and passed through the horizontal bearing 24 from bottom to top through the rear bracket 32 ​​of the reflector mounting frame 152. The horizontal bearing baffle 25 is then passed through the horizontal bearing 24 from above, and the horizontal photoelectric baffle 27 and horizontal photoelectric panel 26 are respectively fixed to the rear bracket 32 ​​of the reflector mounting frame 152 with screws. In this way, the horizontal photoelectric baffle 27, horizontal photoelectric panel 26, horizontal bearing baffle 25, and horizontal bearing 24 are fixed to the rotatable end 1522 of the rear bracket 32 ​​of the reflector mounting frame 152 in sequence.

[0045] Figure 13 Shown Figure 10 A local enlarged schematic diagram of point C is shown. Figure 14 Shown Figure 11 The front assembly diagram of the reflecting mirror 151 and the horizontal rotation motor 21 is shown. Figure 15 Shown Figure 11 The reverse assembly diagram of the reflector 151 and the horizontal rotation motor 21 is shown in FIG. Figure 13As shown, the horizontal rotating motor 21 includes a motor shaft 211, and the motor connecting end 1521 includes a mounting hole 1525, and the mounting hole is a flat structure. The horizontal rotating motor 21 includes a motor shaft 211, and the motor shaft 211 is a flat structure. The motor shaft 211 is inserted into the mounting hole 1525. Specifically, the inner wall of the mounting hole 1525 of the motor connecting end 1521 is provided with a first flat structure along the hole axis direction. The flat structure of the mounting hole 1525 cooperates with the flat structure of the motor shaft 211. Specifically, the outer wall of the motor shaft 211 of the horizontal rotating motor 21 is provided with a second flat structure along the axial direction of the motor shaft 211. In this way, the first flat structure and the second flat structure are limitedly matched, and the horizontal rotating motor 21 can drive the reflector 151 to rotate horizontally.

[0046] Combined with Figure 11 As shown, the motor shaft 211 has a threaded hole (not shown) extending radially along the motor shaft 211. The motor connection end 1521 includes a mounting hole 1523 corresponding to the threaded hole. The axis of the mounting hole 1523 is perpendicular to the axis of the mounting hole 1525. Thus, the motor connection end 1521 is provided with mounting holes 1523 extending radially along the motor connection end 1521, and the mounting holes 1523 pass through the mounting holes 1525. This allows the motor shaft 211 and the motor connection end 1521 of the horizontal rotation motor 21 to be fixed together using screws 1524, eliminating angular motion errors caused by gaps in the flat position.

[0047] Figure 16 Shown Figure 1 The diagram shows a front perspective view of the first lens assembly 13 and the main body housing 18 of the camera 10. Figure 17 Shown Figure 1 FIG. 1 is a rear view of the first lens assembly 13 and the main body housing 18 of the camera 10. Figure 16 and Figure 17 As shown, the first lens assembly 13 also includes a pitch rotation motor 41 connected to the first lens 132. The pitch rotation motor 41 is used to drive the first lens 132 to pitch. In this way, the pitch rotation motor 41 is connected to the first lens 132, driving the first lens 132 to pitch. The horizontal rotation motor 21 drives the reflector assembly 15 to rotate horizontally, and the pitch rotation motor 41 drives the first lens 132 to rotate vertically. Through the principle of reflective imaging, the camera 10 can achieve long-distance and large-scale monitoring. In addition, the pitch rotation motor 41 is connected to the first lens 132, driving the first lens 132 to pitch. The first lens 132 only realizes simple pitch rotation. The pitch structure of the first lens 132 is relatively small, making the overall structure simple, small in size, and low in cost.

[0048] The pitch motor 41 is a direct-drive motor. The motor output shaft 411 of the pitch motor 41 is directly connected to the lens mounting bracket 42 of the first lens assembly 13, with no other transmission components intervening. This provides the pitch motor 41 with a direct drive power source, directly driving the first lens assembly 13. This reduces the number of transmission components, resulting in a compact overall structure with fewer parts and lower costs. This allows for simultaneous horizontal movement of the reflector 151 and vertical movement of the first lens 132, effectively extending the monitoring range of the camera 10.

[0049] Figure 18 Shown Figure 4 The main unit shown is connected to the main unit housing 18. Figure 4 Cross-sectional view along line BB. Figure 19 Shown Figure 1 FIG. 1 is an exploded view of the first lens assembly 13 and the main body housing 18 in the camera 10. Figure 18 and Figure 19 As shown, the first lens assembly 13 further includes a lens mounting bracket 42 for fixedly mounting the first lens 132. The first lens 132 is fixedly mounted on the lens mounting bracket 42. A pitch motor 41 is connected to the lens mounting bracket 42. When the pitch motor 41 rotates, it drives the lens mounting bracket 42 to pitch relative to the front cover 16. In this way, the pitch motor 41 is used to drive the lens mounting bracket 42 to pitch, and the lens mounting bracket 42 is used to drive the first lens 132 to pitch. In this way, the pitch motor 41 directly drives the lens mounting bracket 42, causing the lens mounting bracket 42 and the first lens 132 to pitch together. This reduces the number of transmission components between the first lens 132 and the pitch motor 41, resulting in a compact structure and a small footprint. In this way, the lens mounting bracket 42 and the first lens 132 are fixed together. During the pitching process, the lens mounting bracket 42 and the first lens 132 are relatively stationary, which can reduce the friction generated by the mutual movement between the two, extend the service life of the lens mounting bracket 42 and the first lens 132, and also reduce the reserved moving space and rotating parts, resulting in a compact and exquisite structure.

[0050] The first lens 132 is located on one side of the reflector assembly 15 in the first direction W, the tilt motor 41 is located behind the reflector assembly 15, and the lens mounting bracket 42 extends from the first lens 132 to the rear of the reflector assembly 15 and is connected to the tilt motor 41. This makes it easier for the tilt motor 41 to drive the first lens assembly 13.

[0051] Continue as Figures 16 to 19As shown, the first lens 132 is located on one side of the reflector assembly 15 in the first direction W, the pitch motor 41 is located behind the reflector assembly 15 and includes a motor output shaft 411, and the lens mounting bracket 42 extends from the first lens 132 to the rear of the reflector assembly 15 and is connected to the motor output shaft 411. In this way, the pitch motor 41 drives the lens mounting bracket 42 to move vertically by extending the lens mounting bracket 42 from the first lens 132 to the rear of the reflector assembly 15 and connecting to the motor output shaft 411.

[0052] Figure 20 Shown Figure 18 The local enlarged schematic diagram of F is shown in FIG. Figure 19 and Figure 20 As shown, the tilt motor 41 is located outside the main body housing 18, and the lens mounting bracket 42 is at least partially located inside the main body housing 18. The camera 10 includes a vertical bearing 44. The vertical bearing 44 rotates vertically along with the lens mounting bracket 42 as the tilt motor 41 rotates, reducing friction during vertical rotation and facilitating vertical rotation of the lens mounting bracket 42. The vertical bearing 44 is disposed between the lens mounting bracket 42 and the main body housing 18. The tilt motor 41 drives the lens mounting bracket 42 to rotate relative to the main body housing 18 via the vertical bearing 44. In this manner, the first lens 132 is fixed to the lens mounting bracket 42 to form the first lens assembly 13. The lens mounting bracket 42 passes through the vertical bearing 44 on the main body housing 18 and is connected to the tilt motor 41. The tilt motor 41 can drive the first lens assembly 13 to achieve vertical movement. Furthermore, the reflector 151 is fixed to the reflector mounting bracket 152 to form the reflector assembly 15. The upper portion of the reflector assembly 15 is supported on the main body housing 18 via a horizontal bearing 24, and the lower portion is directly connected to the horizontal rotation motor 21. The horizontal rotation motor 21 can drive the reflector assembly 15 to achieve horizontal movement. This allows for both vertical movement of the first lens 132 and horizontal movement of the reflector 151, thereby increasing the monitoring range of the camera 10.

[0053] The motor output shaft 411 of the pitch motor 41 has a flattened structure, and the shaft mounting hole of the lens mounting bracket 42 has a flattened structure. The motor output shaft 411 is inserted into the shaft mounting hole. The flattened structure of the shaft mounting hole cooperates with the flattened structure of the motor output shaft 411. Thus, through the cooperation of the flattened structures, the pitch motor 41 can drive the lens mounting bracket 42 to vertically rotate. Furthermore, the first lens 132 is fixed to the lens mounting bracket 42 to form the first lens assembly 13. The lens mounting bracket 42 passes through the vertical bearing 44 on the main body housing 18 and is directly connected to the pitch motor 41 through the flattened structure. At the same time, a fastening screw is added to achieve direct drive transmission between the pitch motor 41 and the first lens assembly 13, with high transmission efficiency and a reliable overall structure.

[0054] like Figure 19 As shown, the camera 10 includes a motor mounting bracket 45, which is fixed to the main body housing 18. The pitch rotation motor 41 is installed in the motor mounting bracket 45 and is connected to the main body housing 18 and the lens mounting bracket 42 through the motor output shaft 411 of the pitch rotation motor 41. In this way, it is convenient to fix the pitch rotation motor 41. Figure 19 As shown, the main body housing 18 is provided with a shaft mounting hole 181. The shaft mounting hole 181 can be, but is not limited to, a circular through-hole. The shaft mounting hole 181 mates with the motor output shaft 411. The camera 10 includes a vertical bearing 44. The vertical bearing 44 is disposed between the lens mounting bracket 42 and the shaft mounting hole 181. This allows the motor output shaft 411 of the pitch motor 41 to pass through the shaft mounting hole 181 and the vertical bearing 44, facilitating installation of the vertical bearing 44 and facilitating rotation of the vertical bearing 44 with the motor output shaft 411.

[0055] continue Figure 19 and Figure 20 As shown, a limiting protrusion 1811 is provided on the inner wall of the shaft mounting hole 181. Limiting protrusion 1811 is used to limit the displacement of the sealing ring 51. The camera 10 includes a sealing ring 51, a sealing pressure plate 52, and a bearing pressure plate 53. The sealing pressure plate 52 is fixed to one end of the shaft mounting hole 181. The sealing ring 51 is clamped between the sealing pressure plate 52 and one side of the limiting protrusion 1811. The sealing ring 51 is disposed between the shaft mounting hole 181 and the lens mounting bracket 42. The bearing pressure plate 53 is fixed to the other end of the shaft mounting hole 181. The vertical bearing is clamped between the bearing pressure plate 53 and the other side of the limiting protrusion 1811. This configuration of the sealing ring 51 provides a good and stable damping force and effectively reduces the amount of shaking when the camera is stopped. The sealing ring 51 is a skeleton sealing ring 51, which is stationary relative to the main body housing 18 and has an interference fit with the lens mounting bracket 42. Thus, the sealing method of the skeleton seal ring 51 can provide a good and stable damping force and effectively reduce the amount of shaking in the stopped state. Among them, the skeleton seal ring has a certain interference fit with the shaft mounting hole 181 of the first lens assembly 13, thus providing a more stable damping force.

[0056] continue Figure 19As shown, the camera 10 also includes a vertical photoelectric panel 54 and a vertical photoelectric baffle 55. The vertical photoelectric panel 54 can detect the rotation angle of the first lens 132. The vertical photoelectric panel 54 can also limit displacement of the vertical photoelectric panel 54 in a first direction W. The vertical photoelectric panel 54 is sandwiched between the bearing assembly and the vertical photoelectric baffle 55, which is fixedly connected to the main body housing 18. Thus, the vertical photoelectric panel 54 and the vertical photoelectric baffle 55 rotate along with the motor output shaft 411, detecting the rotation angle of the lens mounting bracket 42 and, in turn, the rotation angle of the first lens 132. The motor output shaft 411 of the pitch motor 41 corresponding to the vertical photoelectric panel 54 has an initial position. The vertical photoelectric panel 54, in conjunction with a photoelectric switch (not shown), can rotate to a specific angle. The photoelectric switch rotates according to a specific rotation angle, such as 15°, 30°, or 45°. The photoelectric switch has a transmitting end and a receiving end. When the vertical photoelectric plate 54 rotates to the corresponding photoelectric switch, it blocks the light emitted from the transmitting end to the receiving end, which records the position of the motor output shaft 411 and the rotation angle. Figure 18 and Figure 19 As shown, the camera 10 includes a counterweight assembly 43 for changing the center of gravity of the first lens assembly 13 .

[0057] Combine Figure 5 As shown, continue Figure 16 、 Figure 18 and Figure 19 As shown, the counterweight assembly 43 includes a first end 433 connected to the pitch motor 41 and a second end 434 opposite to the first end 433. The reflector assembly 15 includes a first side 153 adjacent to the first lens 132 and a second side 154 opposite to the first side 153. The second end 434 extends beyond the second side 154 in the first direction W. In this way, the counterweight assembly 43 protrudes from the second side 154 and is configured outside the main body housing 18, which is also more convenient for installation. The counterweight assembly 43 and the first lens 132 are located on opposite sides of the pitch motor 41 in the first direction W. The counterweight assembly 43 is connected to the motor output shaft 411. When the pitch motor 41 rotates, the counterweight assembly 43 and the first lens 132 are driven to pitch in the same direction. Thus, a counterweight assembly 43 is installed on the other side of the first lens assembly 13, and the counterweight assembly 43 is also connected to the first lens assembly 13. The counterweight assembly 43 and the first lens 132 are respectively located on opposite sides of the motor output shaft 411, so that the center of gravity of the entire first lens assembly 13 is at the axis position supported by the vertical bearing 44, thereby reducing the shaking of the first lens 132 and effectively reducing the driving force of the pitch rotation motor 41. Figure 18 and Figure 19As shown, the counterweight assembly 43 includes a counterweight portion 431 and a mounting portion 432 connected to the counterweight portion 431. The mounting portion 432 is connected between the motor output shaft 411 and the counterweight portion 431. The counterweight portion 431 is farther away from the motor output shaft 411 in the first direction W than the mounting portion 432.

[0058] The lens mounting bracket 42 includes a lens mounting portion 421 for mounting the first lens 132, and a connecting portion 422 connected between the lens mounting portion 421 and the motor output shaft 411. The lens mounting portion 421 is further away from the motor output shaft 411 than the connecting portion 422. The lens mounting portion 421 is used to mount and support the first lens 132. The connecting portion 422 is used to transmit the force of the motor output shaft 411 of the pitch motor 41. The lens mounting portion 421 and the connecting portion 422 can be assembled. The lens mounting portion 421 and the connecting portion 422 are integrally formed. The mounting portion 432 and the connecting portion 422 extend from radially opposite sides of the motor output shaft 411 and in opposite directions along the axial direction of the motor output shaft 411, respectively. The lens mounting portion 421 extends forward from the connecting portion 422. As such, the distance between the center of gravity of the counterweight assembly 43 and the motor output shaft 411 is proportional to the distance between the center of gravity of the first lens 132 and the motor output shaft 411. The counterweight assembly 43 rotates along with the motor output shaft 411 of the pitch motor 41. Because the first lens 132 has an eccentric rotation axis, the embodiment of the present application rotates around the motor output shaft 411, which requires excessive driving force from the pitch motor 41. By using the counterweight assembly 43, the center of gravity of the first lens assembly 13 is positioned perpendicular to the bearing support axis, effectively reducing the driving force of the pitch motor 41 and minimizing lens shake during movement.

[0059] Among them, the counterweight part 431 includes a regularly shaped plate-like structure or a regularly shaped block-like structure. Such a regular shape facilitates the arrangement of the counterweight part 431 and can also achieve stable counterweighting during the vertical rotation of the counterweight part 431. A regular shape is, for example, a sphere. A regular shape is, for example, a hexahedron. Examples are not given here one by one. The counterweight part 431 is symmetrical in terms of the mounting part 432. The counterweight part 431 extends rearward from the mounting part 432. The counterweight assembly 43 is located outside the main body housing 18. In this way, the counterweight part 431 is easy to install. The mounting part 432 is located on the rear side of the connecting part 422. The mounting part 432 and the connecting part 422 are symmetrical in terms of the radial direction of the motor output shaft 411. This facilitates the installation of the counterweight assembly. The counterweight part 431 protrudes rearward and forward from the mounting part 432 and is symmetrical front to back relative to the mounting part 432. In this way, the counterweight assembly has a simple structure and the symmetrical structure makes it more conducive to counterweighting. The lens support portion 421 is symmetrical with respect to the connecting portion 422. Thus, the structure is simple and easy to set up. Figures 18 to 20As shown, the counterweight assembly 43 includes a vertical cushion 46 fixed to the mounting portion 432. This cushion acts as an effective buffer when the product is not powered on and the motor is not driving it. Furthermore, when the counterweight assembly 43 rotates with the motor output shaft 411, it provides a cushioning effect, reducing damage caused by mutual compression between components.

[0060] Figure 21 Shown Figure 16 A schematic diagram of the main body housing 18 and the vertical bearing 44 is shown. Figure 22 Shown Figure 21 The local enlarged schematic diagram of H is shown in FIG. Figures 20 to 22 As shown, the skeleton seal ring is pressed into the main body housing 18, and the outer seal pressure plate 52 is installed on the main body housing 18 with screws to prevent the skeleton seal ring from falling out. On the other side, the vertical bearing 44 is mounted on the main body housing 18, and the bearing pressure plate 53 is installed on the fixed housing 1 with screws. The bearing pressure plate 53 presses on the vertical bearing 44 to prevent the vertical bearing 6 from falling out and limit its position.

[0061] Figure 23 Shown Figure 10 The local enlarged schematic diagram of G is shown in FIG. Figure 19 and Figure 23 The assembly process of the first lens assembly 13 and the main body shell 18 shown in the figure is as follows: the mounting shaft that matches the first lens assembly 13 with the motor output shaft 411 is passed through the inner hole of the vertical bearing 44 on the main body shell 18 from one side of the main body shell 18, and the mounting part 432 of the counterweight assembly 43 is also passed through the inner hole of the vertical bearing 44 on the other side of the main body shell 18, and the counterweight assembly 43 and the first lens assembly 13 are installed together with screws to form a vertical rotating part.

[0062] like Figure 19 and Figure 23The assembly process of the vertical photoelectric panel 54 and vertical photoelectric baffle 55 shown in FIG is as follows: the vertical photoelectric panel 54 is mounted on the main body housing 18, and the vertical photoelectric baffle 55 structure is designed on the counterweight assembly 43. During vertical rotation, the vertical photoelectric baffle 55 can detect the rotation angle of the first lens 132 via a photoelectric switch. The pitch rotation motor 41 used to drive the pitch rotation of the first lens assembly 13 is mounted to the motor mounting bracket 45 via four screws to form an assembly. Then, the motor output shaft 411 of the pitch rotation motor 41 is inserted into the corresponding mounting hole of the counterweight assembly 43. The motor output shaft 411 of the pitch rotation motor 41 is designed with a flattening structure, and the mounting hole of the counterweight assembly 43 is also designed with a flattening structure. Through the flattening structure, the pitch rotation motor 41 can drive the counterweight assembly 43 and the first lens assembly 13 to perform vertical rotational movement. At the same time, the motor output shaft 411 of the pitch motor 41 also has a threaded hole, and the counterweight assembly 43 has a mounting hole at the corresponding position. The motor output shaft 411 of the pitch motor 41 and the counterweight assembly 43 can be fixed together by screws, which can eliminate the motion angle error caused by the flat position fit clearance. After the pitch motor 41 is installed, the entire vertical transmission part is completely installed. Based on the above installation process, the reflector assembly 15 is subsequently installed on the main body housing 18. At this point, the entire reflector assembly 15 and the first lens assembly 13 are completely installed, forming a camera 10 with the reflector assembly 15 and the first lens assembly 13.

[0063] Figure 24 Shown Figure 19 An exploded schematic diagram of the first lens 132 and the lens holder is shown. Figure 25 Shown Figure 19 The assembly diagram of the first lens 132 and the lens bracket is shown in FIG. Figure 24 As shown, the first lens assembly 13 further includes a decorative cover 135. The decorative cover 135 can be wrapped around the first lens 132 to protect the first lens 132 and connect the first lens 132 to the lens mounting bracket 42. The decorative cover 135 is connected to the lens mounting bracket 42, and the first lens 132 is accommodated between the decorative cover 135 and the lens mounting bracket 42. In this way, the decorative cover 135 protects the first lens 132 and connects the first lens 132 to the lens mounting bracket 42, thereby improving the safety of the first lens 132.

[0064] like Figure 24As shown, the decorative cover 135 may include a first cover body 1351 and a second cover body 1352, and the second cover body 1352 is covered on the rear end of the first cover body 1351. The first cover body 1351 includes a first port 1353 for the first lens 132 to receive light, and the rear end cover opposite to the first port is provided with a second cover body 1352. The first cover body 1351 is buckled with the lens mounting bracket 42. In this way, the first lens 132 is mounted on the lens mounting bracket 42 by screws, and the first cover body 1351 and the second cover body 1352 are buckled on the lens mounting bracket 42 in the form of buckles, so that the main body of the first lens 132 is not exposed, which can protect the entire main body of the first lens 132, as shown in FIG. Figure 25 shown.

[0065] Figure 26 Shown Figure 1 A schematic diagram of the wiring harness 64 and the main body housing 18 in the camera 10 is shown. Figure 27 Shown Figure 26 The wiring harness 64 is shown as an exploded view of the main body housing 18. Figure 2 and Figure 3 As shown, the front cover 16 includes a first cover side wall 166 and a second cover side wall 164 that are opposite to each other in the first direction W. The first through-hole 161 includes a first hole edge 1611 and a second hole edge 1612 that are opposite to each other in the first direction W. The first hole edge 1611 is closer to the first cover side wall 166 than the second hole edge 1612. A first space 165 is defined between the first hole edge 1611 and the first cover side wall 166. This first space 165 allows room for the reflector 151 to rotate horizontally, avoiding interference with the front cover 16. A second space (not shown) is defined between the second hole edge 1612 and the second cover side wall 164. This second space (not shown) allows room for the first lens 132 to tilt, avoiding interference with the front cover 16 and allowing for more flexible tilting of the first lens 132. The first space 165 is smaller than the second space (not shown).

[0066] like Figure 26 and Figure 27As shown, the first lens assembly 13 includes a lens circuit board 61. The lens circuit board 61 is used to transmit control signals. The first lens 132, lens mounting bracket 42, and reflector 151 are each housed within the main body housing 18. The first lens 132 is positioned relative to the first cover sidewall 166 and near the second cover sidewall 164. It is located on the side of the reflector 151 near the second aperture edge 1612. The first lens 132 includes a head 1321 and a tail 1322. The head 1321 faces the first cover sidewall 166, and the tail 1322 is located within the second space. The lens circuit board 61 is located at the tail 1322, with a gap between it and the second cover sidewall 164. The pitch motor 41 is located on the rear side of the main body housing 18, opposite the reflector 151. The lens mounting bracket 42 connects the pitch motor 41 and the first lens 132. The pitch motor 41 drives the first lens 132 to tilt through the lens mounting bracket 42. There is a wiring harness avoidance space 62 between the lens mounting bracket 42 and the side wall of the main body shell 18 in the first direction W close to the lens circuit board 61. The wiring harness avoidance space 62 is used to prevent the wiring harness 64 from interfering with other components, and the wiring harness avoidance space 62 is connected to the second space.

[0067] Continue as Figure 26 and Figure 27 As shown, a winding assembly 63 is provided on the outside of the main body housing 18. The winding assembly 63 is used to provide a winding fulcrum for the wire harness 64. The winding assembly 63 is staggered with the pitch motor 41. The camera 10 includes a main board (not shown in the figure) provided outside the main body housing 18, and a wire harness 64 electrically connecting the lens circuit board 61 and the main board. The wire harness 64 extends from the lens circuit board 61 through the second space into the wire harness avoidance space 62, passes through the main body housing 18 from the wire harness avoidance space 62, is wound around the winding assembly 63 at least once, and is then connected to the main board. In this way, the wire harness 64 is fixed by the tail 1322 of the first lens 132, and the routing layout of the wire harness 64 is adjusted to prevent the up and down swinging of the first lens 132 and the lens mounting bracket 42 from affecting the life of the wire harness 64, thereby improving the service life of the wire harness 64. Furthermore, the wiring harness 64 can avoid the pitch rotation motor 41 and does not interfere with the pitch rotation motor 41, thereby improving the service life of the wiring harness 64 and the safety of the use of the wiring harness 64. The wiring harness 64 can be a signal line for transmitting signals or a power line for power supply. Optionally, the wiring harness 64 can be an FPC (Flexible Printed Circuit board) line, also known as a soft cable. The wiring harness 64 is mainly used to transmit high-speed signals such as images. On the camera 10, the wiring harness 64 is used to connect the main boards of the first lens assembly 13 and the second lens assembly 14. Due to its poor bending and torsion resistance, it is generally used in relatively static connection solutions. At the same time, the wiring harness 64 of the present application eliminates the coaxial line, which significantly saves costs while improving the service life of the wiring harness 64.

[0068] Figure 28 Shown Figure 27 A schematic diagram of the wiring harness 64 and the lens mounting bracket 42 is shown. Figure 29 Shown Figure 28 The local enlarged schematic diagram of J is shown in FIG. Figure 28 and Figure 29 As shown, the lens mounting bracket 42 includes a bracket back side 423 facing the harness avoidance space 62 in the first direction W. The harness 64 is fixed to the lens mounting bracket 42 here so that this part of the harness 64 and the first lens 132 are in a relatively static state. The camera 10 includes a limiting harness seat 65 for limiting the direction of the harness 64. The limiting harness seat 65 is used to limit the movement of the first harness segment 641. The limiting harness seat 65 is provided on the bracket back side 423. The harness 64 includes a first harness segment 641 and a second harness segment 642 that are connected to each other. One end of the first harness segment 641 is connected to the lens circuit board 61. The first harness segment 641 can be movably limited to the limiting harness seat 65 and moves with the first lens 132 and the lens mounting bracket 42. The other end of the first harness segment 641 is fixed to the rear face 423 of the bracket and connected to the second harness segment 642. The second harness segment 642 winds at least one turn around the winding assembly 63. The first harness segment 641 pitches and tilts with the lens mounting bracket 42, while the second harness segment 642 retracts and extends around the winding assembly 63. In this way, the position-limiting harness seat 65 provided on the lens mounting bracket 42 restricts the direction of the harness 64, allowing it to adhere closely to the outer wall of the lens mounting bracket 42 and avoid interference with other components.

[0069] continue Figure 26 and Figure 28 As shown, the second wiring harness section 642 includes an extension section 6421 and a winding section 6422 connected to the extension section 6421. The extension section 6421 extends from the first wiring harness section 641 to the winding assembly 63. The winding assembly 63 extends horizontally. The winding section 6422 is spirally wound around the winding assembly 63 in a first direction W, and there is a gap between the winding assembly 63 and the winding assembly 63 in the vertical direction. When the first lens 132 pitches, the winding section 6422 retracts and extends around the winding assembly 63, and moves up and down relative to the winding assembly 63. In this way, when the extension section 6421 moves with the first lens 132 and the lens mounting bracket 42, it may be extended or shortened by the swing. In addition, the corresponding space left in the extension section 6421 can ensure the up and down swing of the first lens 132, and can effectively prevent the wiring harness 64 from twisting itself during movement, thereby improving the service life of the wiring harness 64. The winding segment 6422 is wound around the winding assembly 63, changing the movement of the wire harness 64 from free swinging to spiral motion along the tangential direction of the winding assembly 63. After the winding segment 6422 is wound around the winding assembly 63, it is fixed at a positioning point set at its end to prevent the winding segment 6422 from shifting.

[0070] like Figure 28 and Figure 29 As shown, the harness retainer 65 includes a harness guide hole 651 that extends horizontally through the harness. The harness 64 passes through the harness guide hole 651. The end 6411 of the harness 64 connected to the lens circuit board 61 is vertically positioned within the height range of the harness guide hole 651. This end 6411 of the harness 64 can be inserted into a corresponding receptacle on the mainboard. Thus, the harness guide hole 651 allows the harness 64 to pass through, facilitating both direction control and securement.

[0071] continue Figure 29 As shown, the position-limiting harness seat 65 includes a buckle 652, which includes a buckle connection portion 6521 and a position-limiting hook 6522 connected to the buckle connection portion 6521. The buckle connection portion 6521 is fixed to the bracket back surface 423, and the position-limiting hook 6522 is connected to the side of the connection portion facing away from the bracket back surface 423. The harness 64 enters the position-limiting harness seat 65 through the position-limiting hook 6522. In this way, the harness 64 is secured to the bracket back surface 423 of the lens mounting bracket 42 using the buckle 652 of the harness 64, making it easy to insert the harness 64 through the position-limiting hook 6522 and secure the position-limiting harness seat 65 via the buckle connection portion 6521.

[0072] continue Figure 28 As shown, the limiting harness seat 65 includes a first limiting harness seat 66 and a second limiting harness seat 67. The first limiting harness seat 66 is located at the front end of the lens mounting bracket 42 near the lens circuit board 61, and the second limiting harness seat 67 is located at the rear end of the lens mounting bracket 42. A section of the harness 64 extends from the first limiting harness seat 66 to the second limiting harness seat 67. The first limiting harness seat 66 includes a first harness guide hole 651 that passes horizontally through the harness, and the second limiting harness seat 67 includes a second harness guide hole 651 that passes horizontally through the harness. The first harness guide hole 651 and the second harness guide hole 651 are perpendicular to each other in their respective penetration directions. The harness 64 passes through the first harness guide hole 651 and the second harness guide hole 651 in their respective penetration directions. In this way, the first limiting harness seat 66 and the second limiting harness seat 67 can limit the range of movement of the harness 64 as much as possible while fixing the routing direction of the harness 64 to avoid interference with other devices during movement, such as avoiding movement of the harness 64 relative to the first lens 132 and the lens mounting bracket 42, thereby improving the stability of the harness 64.

[0073] Continue as Figure 28 and Figure 29As shown, the camera 10 includes a fixed harness mount 68, which is located on the back side 423 of the bracket. Relative to the limited harness mount 65, the fixed harness mount 68 is positioned away from the lens circuit board 61 and closer to the winding assembly 63. The end of the first harness segment 641, away from the lens circuit board 61, is secured to the back side 423 of the bracket via the fixed harness mount 68. This constrains and secures the harness 64, preventing movement. After passing through the winding assembly 63, the harness 64 is connected to the mainboard. The end of the harness 64 located in the winding assembly 63 can also be secured using the fixed harness mount 68.

[0074] The installation process of the above-mentioned first lens and wiring harness is as follows: fix the first lens 132 and the lens mounting bracket 42 with screws, and insert the wiring harness into the corresponding seat of the lens circuit board 61 at the tail 1322 of the first lens 132. The wiring path of the wiring harness is constrained by two wiring harness 64 buckles, while preventing interference with other devices during the movement of the wiring harness driven by the lens. After the wiring harness 64 is inserted into the seat, it first passes through the first wiring harness 64 buckle so that the wiring harness 64 can be close to the lens mounting bracket 42; then, according to the preset wiring path, it passes through the first limiting wiring harness seat 66 and the second limiting wiring harness seat 67. The wiring harness between the first limiting wiring harness seat 66 and the second limiting wiring harness seat 67 is in the form of being close to the lens mounting bracket 42. Its main purpose is to prevent the free swing of the wiring harness 64 from causing interference with other devices.

[0075] Figure 30 Shown Figure 27 A side view of the wiring harness 64 and the lens mounting bracket 42 is shown. Figure 29 and Figure 30 As shown, a first harness plug 69 is fixedly mounted on the outside of the harness 64, filling the space between the harness 64 and the first securing buckle 681 and restricting its movement. Passing the harness 64 through the first harness plug 69 also serves to secure the harness 64. The harness holder 68 includes a first securing buckle 681 mounted on the lens mounting bracket 42. The first securing buckle 681 holds the first harness plug 69, securing it relative to the lens mounting bracket 42. This facilitates insertion of the harness 64 through the first securing buckle 681 and securement of the harness 64 to the back surface 423 of the lens mounting bracket 42 using the first harness plug 69.

[0076] In other embodiments, glue is used to adhere the first fixing buckle 681 of the harness seat 68 and the harness 64 together. In this way, a harness fixing point is provided near the first fixing buckle 681 on the outside, and the harness fixing point is set as a glue point, and the harness 64 is fixed by applying glue. The purpose of setting the harness fixing point is to ensure that the harness 64 moves as little as possible within the range of the lens mounting bracket 42. After the harness 64 passes through the fixing point with the lens mounting bracket 42, it is fixed with the Figure 30The wire harness 64 is wound around the winding assembly 63 in the manner described above, with the wire entry direction of the wire harness 64 being tangential to the winding assembly 63. This method converts the torsional motion of the wire harness 64 into up and down motion tangential to the winding assembly 63. The two aforementioned embodiments secure the wire harness 64, and the preferred method for securing the wire harness 64 can be selected based on the actual application. The adhesive can be tape or glue. When the adhesive is tape, the tape can be used to position the wire harness 64 at the position corresponding to the first fixing buckle 681, facilitating installation.

[0077] continue Figure 28 and Figure 30 As shown, the fixed harness seat 68 is located below and behind the position-limiting harness seat 65, and the winding assembly 63 is located below the fixed harness seat 68. The harness 64 extends from the position-limiting harness seat 65, extending diagonally downward to the fixed harness seat 68, and then extending downward to the winding assembly 63. In this way, based on the first position-limiting harness seat 66 and the second position-limiting harness seat 67, the routing of the harness 64 is constrained, and the stability of the harness 64 is improved by the fixed harness seat 68. Furthermore, the fixed harness seat 68 includes a harness plug. The internal structure of the harness plug is relatively stable, preventing interference when the first lens 132 drives the harness 64. The winding assembly 63 includes a winding post 631 protruding from the main body housing 18. The winding post 631 is spaced apart from the pitch motor 41 and staggered with the pitch motor 41 and the first lens 132, respectively, and is located below the pitch motor 41 and the first lens 132. The wiring harness 64 includes a winding section 6422 wound around the winding post 631, which spirally extends from one end to the other. Thus, by designing the routing of the wiring harness 64, the movement of the wiring harness 64 is changed from free movement to spiral movement around the winding post 631, limiting the torsion of the wiring harness 64 itself. This improves the service life of the wiring harness 64 while ensuring that the first lens 132 can move normally.

[0078] In such Figure 28 and Figure 30 In the illustrated embodiment, the winding post 631 extends in a second direction Q perpendicular to the first direction W and is arranged on the rear side of the main body housing 18, and the two ends of the winding section 6422 are located on the side of the winding post 631 in the first direction W away from the pitch rotation motor 41. The second direction Q can be the first direction W and is a front-to-back direction. In this way, the winding post 631 occupies the space in the second direction Q, making it convenient to set up the winding post 631. Among them, one end of the winding post 631 is connected to the rear side of the main body housing 18. In this way, the axial direction of the winding post 631 is perpendicular to the main body housing 18, reducing the space occupied by the main body housing 18.

[0079] like Figure 30As shown, a wire harness fixing structure 6311 is provided circumferentially around the winding post 631. The end of the winding section 6422 closest to the mainboard is fixed to the wire harness fixing structure 6311, and is then fixed to the winding post 631 via the wire harness fixing structure 6311. Thus, the wire harness 64 is fixed by the wire harness fixing structure 6311 of the winding post 631. Furthermore, a wire harness fixing structure 6311 is also provided at the end of the winding assembly 63. The fixing scheme of the wire harness fixing structure 6311 is the same as that of the wire harness seat 68. Depending on actual needs, a corresponding fixing scheme can be adopted.

[0080] continue Figure 30 As shown, the winding section 6422 is provided with a second harness plug 60, and the harness fixing structure 6311 includes a second fixing buckle 682, which securely holds the second harness plug 60. In another embodiment, a fixing point is added to the winding post 631, and the wire harness 64 is wound around the winding post 631 added to the harness fixing structure 6311 through the fixing point. The end of the winding post 631 is provided with an adhesive point for fixing the wire harness 64, enhancing the stability of the wire harness 64 and preventing it from falling off, thereby failing to achieve the design purpose of the structure.

[0081] Figure 31 Shown is a schematic diagram of another embodiment of the winding rod 631 in the camera 10 of the present application. Figure 31 In the embodiment shown, the winding post 631 extends in the first direction W and is arranged on the main housing 18, and the two ends of the winding section 6422 are located on the side of the winding post 631 away from the pitch rotation motor 41 in the second direction Q. In this way, the winding section 6422 of the winding post 631 can avoid the pitch rotation motor 41, reducing the interference between the wire harness 64 and the pitch rotation motor 41. Among them, both ends of the winding post 631 are connected to the rear side of the main housing 18. In this way, the axial direction of the winding post 631 is parallel to the main housing 18, reducing the space occupied by the camera 10 in the second direction Q, and can enhance the stability of the winding post 631 connected to the main housing 18. In this way, the axial direction of the winding post 631 is parallel to the direction of the first lens 132, and the winding post 631 is fixed to the wire harness fixing structure 6311 by screws. After passing through the wire harness fixing structure 6311, the wire harness 64 is also wound on the winding post 631. As shown in the example Figure 30 The winding post 631 scheme shown is different in that this directional winding post 631 can save space, but this scheme is more complicated to install. The setting scheme of the winding post 631 can be selected according to actual needs.

[0082] Figure 32 Shown Figure 28 The diagram shows the change in relative position of the wire harness 64 and the winding rod 631 when the lens tail 1322 moves from the highest point to the lowest point. Figure 26 、 Figure 28 and Figure 32 As shown, when the first lens 132 moves in the third direction UR, the wire harness 64 can move up and down along the axial direction of the winding rod 631. Figure 32 The diagram shows the change in the relative position of the harness 64 and the winding post 631 when the tail portion 1322 of the first lens 132 moves from the highest point to the lowest point. When the tail portion 1322 of the first lens 132 is at the highest point, a margin is left between the harness 64 and the winding post 631 to prevent pulling on the harness 64. The third direction UR is perpendicular to the first direction W and the second direction Q, respectively, and the third direction UR can be a vertical direction.

[0083] Figure 33 Shown Figure 1 Another stereoscopic diagram of the camera 10 is shown, wherein the fill light assembly is shown. Figure 33 As shown, the front cover 16 further includes a third through-hole 163. The camera 10 further includes a fill light assembly 71 located within the third through-hole 163. The third through-hole 163 is configured to avoid the fill light assembly 71, allowing the light from the fill light assembly 71 to illuminate the monitoring area. Thus, the fill light assembly 71 is configured to emit light to pass through the front cover 16 and illuminate the monitoring area.

[0084] The fill light assembly 71 is disposed between the front cover 16 and the main body housing 18, and is located on the same side of the reflector 151 as the second lens assembly 14 in the vertical direction. The horizontal rotation motor is located behind the fill light assembly 71 within the main body housing 18. The fill light assembly 71 disposed in the front cover 16, the horizontal rotation motor is located behind the fill light assembly 71, and the fill light assembly 71 is arranged within the third through hole 163, which occupies a small space and can make the camera 10 more compact.

[0085] The first through hole 161 is located above the second through hole 162 and the third through hole 163. The second through hole 162 and the third through hole 163 are arranged adjacent to each other, and the area of ​​the first through hole 161 is larger than that of the second through hole 162. Compared with the related art in which a fill light assembly 71 is provided for each lens separately, which is relatively large in size, the camera 10 in the embodiment of the present application has a first lens assembly 13 and a second lens assembly 14 to achieve monitoring and linked capture, wherein the imaging of the first lens assembly 13 uses a reflector 151 for imaging. In order to ensure that the fill light of the first lens assembly 13 and the second lens assembly 14 can meet the needs of night time, and at the same time to keep the size of the device as small as possible, the fill lights do not interfere with each other. At the same time, the first lens assembly 13 can achieve coverage of a large field of view through P, so as to achieve linked capture, and at the same time, the installation and field of view coverage of the first lens assembly 13 and the second lens assembly 14 are achieved. In addition, the first through hole 161 is located above the second through hole 162 and the third through hole 163, and the second through hole 162 and the third through hole 163 are arranged adjacent to each other, so that light can be supplied to the second through hole 162 and the first through hole 161 at the same time. In this way, the first lens assembly 13 and the second lens assembly 14 use the same fill light plate, thereby achieving the smallest equipment size and the best fill light solution.

[0086] The second through hole 162 and the third through hole 163 are arranged horizontally. In this way, the light from the third through hole 163 can more easily illuminate the second through hole 162 to fill in the light for the second lens assembly 14, and at the same time illuminate the first through hole 161 to fill in the light for the first lens assembly 13.

[0087] continue Figure 33 As shown, the second through hole 162 includes a first side 1621 and a second side 1622 that are opposite to each other in the first direction W. The third through hole 163 includes a third side 1631 and a fourth side 1632 that are opposite to each other in the first direction W. The second side 1622 and the third side 1631 are adjacent to each other, and the horizontal distance between the first side 1621 and the fourth side 1632 is less than or equal to the horizontal dimension of the first through hole 161. In this way, the second through hole 162, the third through hole 163, and the first through hole 161 save space and have a compact structure.

[0088] The vertical dimension of the first through hole 161 is greater than that of the second through hole 162. The vertical dimension of the first through hole 161 is also greater than that of the third through hole 163. Thus, with horizontal and vertical motion highly integrated into a single main body housing 18, the overall size of the camera 10 is reduced. Combined with this fill light solution, the overall structure is extremely compact, with fewer parts and low cost.

[0089] continue Figure 33As shown, the fill light assembly 71 includes a lamp assembly mounting hole 72 and a lamp assembly mounting surface 73 . The lamp assembly mounting hole 72 passes through the lamp assembly mounting surface 73 so as to fix the fill light assembly 71 to the front cover 16 .

[0090] Figure 34 Shown Figure 33 The local enlarged schematic diagram of K is shown. Figure 33 and Figure 34 As shown, the fill light assembly 71 includes a first group of fill lights 711, a second group of fill lights 712, and a third group of fill lights 713. The first group of fill lights 711 is used to provide fill light for the second lens assembly 14, the second group of fill lights 712 is used to provide fill light for the zoom extension structure of the first lens assembly 13, and the third group of fill lights 713 is used to provide fill light for the zoom shortening structure of the first lens assembly 13.

[0091] The first group of fill lights 711 is closer to the second lens assembly 14 than the second group of fill lights 712 and the third group of fill lights 713. The first group of fill lights 711 provides fill light for the monitoring area covered by the second lens assembly 14. The second group of fill lights 712 and the third group of fill lights 713 are also closer to the first lens assembly 13 than the first group of fill lights 711. The second group of fill lights 712 provides fill light for the monitoring area covered by the first lens assembly 13 at its minimum focal length, and the third group of fill lights 713 provides fill light for the monitoring area covered by the first lens assembly 13 at its maximum focal length. This way, the fields of view of the first lens assembly 13 and the second lens assembly 14 overlap, allowing the first, second, and third groups of fill lights 711, 712, and 713 to achieve optimal fill light effects while ensuring their dimensions are kept as small as possible.

[0092] continue Figure 33 and Figure 34 As shown, the first group of fill lights 711, the second group of fill lights 712, and the third group of fill lights 713 are arranged horizontally in sequence. The first group of fill lights 711 is closer to the second lens assembly 14 in the first direction W than the second group of fill lights 712 and the third group of fill lights 713. The first lens assembly 13 includes a first lens 132, which is located above the third group of fill lights 713. In this way, the first group of fill lights 711, the second group of fill lights 712, and the third group of fill lights 713 are arranged horizontally in sequence, making the device compact. Moreover, based on the implementation of linked imaging, the first lens assembly 13 and the second lens assembly 14 achieve unified fill light, also achieving a compact structure. The same lens can achieve two-way lens fill light without interference.

[0093] continue Figure 34As shown, the first group of fill lights 711, the second group of fill lights 712, and the third group of fill lights 713 each include at least two lamp beads. The at least two lamp beads include a first lamp bead 7111 and a second lamp bead 7112. The at least one first lamp bead 7111 and the at least one second lamp bead 7112 are arranged vertically. In each row of the fill light assembly 71 in the second direction Q, the multiple first lamp beads 7111 and the multiple second lamp beads 7112 are arranged alternately. In this way, the multiple first lamp beads 7111 and the multiple second lamp beads 7112 in each row in the second direction Q of the fill light assembly 71 are alternately arranged, closely arranged, and the lamp beads complement each other, thereby improving the fill light effect.

[0094] The first, second, and third groups of fill lights 711, 712, and 713 can be activated in groups or individually. The energy of each group of fill lights can also be controlled based on different distances, specifically the percentage of fill light energy. This is not a limitation. The lamp beads are tilted from top to bottom, toward the rear of the camera 10. This slanted placement and close arrangement of the lamp beads minimizes the structural area. Furthermore, each lamp bead is elliptical in shape, with a short axis of 10 mm and a long axis of 11 mm, and 12 mm spacing between each bead. This slanted placement and close arrangement of the lamp beads simultaneously achieves a fill light effect. Furthermore, the lamp beads are elliptical in shape, with their short axes arranged horizontally and their long axes arranged vertically. This allows for limited space in the second direction Q, allowing the horizontal placement of the lamp beads to minimize space in the second direction Q. The diameter of the first lamp bead 7111 is smaller than that of the second lamp bead 7112.

[0095] Figure 35 Shown Figure 1 A schematic diagram of the radar module 80 and the front cover 16 in the camera 10 is shown. Figure 36 Shown Figure 35 The exploded view of the radar module 80 and the front cover 16 is shown. Figure 35 and Figure 36 As shown, the camera 10 also includes a radar module 80, which can be detachably or fixedly mounted on the bottom of the camera 10. This allows for dynamic control of the fill light and response to environmental protection strategies. The radar module 80 refers to radio detection and ranging, which uses radio to detect targets and determine their spatial positions. Therefore, the radar module 80 is also referred to as "radio positioning." The radar module 80 is an electronic device that uses electromagnetic waves to detect targets. The radar module 80 transmits electromagnetic waves to illuminate the target and receives the echoes, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, and altitude. Applications of this radar module 80 in the security field include perimeter security monitoring, secure entrances, and checkpoints.

[0096] Figure 37 Shown Figure 36 FIG. 8 is an exploded view of the radar module 80. Figures 35 to 37 As shown, the radar module 80 is mounted below the housing 19. The radar module 80 includes a longitudinally extending radome 83 and a radar panel 84 disposed within the radome 83. The dimensions of the hollow cavity 86 formed by the radome 83 in a second direction Q are smaller than those in a first direction WQ perpendicular to the second direction Q. The radar panel 84 faces the front of the radome 83. The hollow cavity 86 enclosed by the radome 83 does not share a common cavity with the hollow cavity 86 enclosed by the housing. This modular design allows the radar module 80 to be assembled separately as a component, rather than being produced on the final assembly line on the front cover 16. This effectively improves production efficiency, shortens the final assembly line length, reduces production costs, and improves final assembly efficiency.

[0097] The camera 10 is configured to trigger the fill light assembly to illuminate and / or the first lens assembly 13 to capture an image when the radar module 80 detects a monitored object entering the monitoring area. Thus, the radar module 80 is mounted below the housing 19, and the hollow cavity 86 enclosed by the radome 83 and the hollow cavity 86 enclosed by the housing are not shared. This arrangement reduces the volume of the front cover 16 and its decorative components, simplifies the structural design of the front cover 16, reduces mold costs for component production, and reduces the cost of the entire device. It also facilitates the layout of other modules on the front cover 16.

[0098] The radar cover 83 is integrally molded. This facilitates casting and assembly of the radar cover 83 with the front cover 16. Upon detecting a monitored object, the radar module 80 triggers the activation of the fill light. Different fill light strategies are implemented based on the distance between the user and the device to mitigate glare and reduce eye irritation, while also achieving environmental protection. The monitored object may include, but is not limited to, moving objects. These include humans and vehicles, among other things, which are not listed here. The radar module 80 detecting that the monitored object has entered the monitoring area may mean that the monitored object is detected to be within a predetermined distance, and the data is actively reported to the microcontroller via the serial port, which in turn signals the activation of the fill light assembly. The predetermined distance may be determined by the ranging function of the radar module 80 itself. The predetermined distance may be greater than 50 meters or less than 200 meters, without limitation. For example, the predetermined distance may be 50 meters.

[0099] Combine Figure 2 and Figure 35As shown, the orientation direction of the radar module 80 is the same as the orientation direction of the second lens assembly 14. In this way, the installation direction of the radar module 80 is no longer on the same surface of the front cover 16 as the installation direction of the second lens assembly 14 as before, but is installed at a 90° direction to the second lens assembly 14, and the radar module 80 extends longitudinally. This can reduce the volume of the front cover 16 and the front cover 16 decorative parts of the camera 10, which is more conducive to the layout of other modules on the front cover 16. The reduction in the volume of the front cover 16 and the front cover 16 decorative parts can effectively reduce the mold cost, thereby reducing the cost of the entire machine production. At the same time, the area photographed by the second lens assembly 14 can be used as the monitoring area of ​​the radar module 80, so that when the radar module 80 detects that the monitored object enters the monitoring area, it triggers the fill light assembly to light up and / or triggers the first lens assembly 13 to capture an image. Continue to combine Figure 2 and Figure 35 As shown, the radar module 80 is disposed in an area more inclined toward the lower portion of the front cover 16 in the second direction Q and does not protrude from the front cover 16 in the second direction Q. Thus, the radar module 80 is located in an area more inclined toward the front cover 16 in the front-to-back direction at the bottom of the camera 10, which facilitates the radar module 80 to detect the forward monitoring area.

[0100] Figure 38 Shown Figure 37 An exploded schematic diagram of the radar support frame 82 and the radar panel 84 is shown.

[0101] like Figure 37 and Figure 38 As shown, the radar module 80 includes a radar support frame 82, which is connected to the radar board 84 and is located on the back of the radar board 84. In this way, the radar support frame 82 is used to support the radar board 84, and the radar support frame 82 is located on the back of the radar board 84, which does not affect the radar board 84 from transmitting radar waves. Figure 38 As shown, the radar support frame 82 includes a support frame body 821 and multiple support protrusions 822 extending from the support frame body 821. The multiple support protrusions 822 are distributed on the side of the support frame body 821 facing the radar board 84 and are fixedly connected to the radar board 84. These support protrusions 822 provide balanced support for the radar board 84, evenly distributing the gap between the radar support frame 82 and the radar board 84 and improving the penetration of the radar board 84. The support protrusions 822 have the same protruding length. The support protrusions 822 may be supporting columns. The number of support protrusions 822 is even and symmetrically distributed on the support frame body 821. Each support protrusion 822 defines a connection hole 8221 facing the radar board 84. Screws 87 penetrate through holes 841 in the radar board 84 and connect to the connection hole 8221 to secure the radar support frame 82 to the radar board 84.

[0102] Figure 39 Shown Figure 36 A schematic structural diagram of the bottom wall 191 of the shell body is shown.

[0103] like Figure 39 As shown, the single opening 88 of the hollow cavity 86 of the radar module 80 faces the bottom wall 191 of the housing 19. The front face 801 of the radar module 80 in the second direction Q is configured to transmit radar waves. Both the front face 801 of the radar module 80 and the front cover 16 face the monitored area in the second direction Q. Thus, the front face 801 of the radar module 80 serves as a radar penetration surface for transmitting radar waves. The radar plate 84 and the radar penetration surface of the radome 83 are aligned in the same direction, ensuring a uniform gap between them. Furthermore, the front face 801 of the radar module 80 directly projects radar waves, eliminating the need for a sealing ring. This prevents uneven gaps between the penetration plane of the radar module 80 and the radar plate 84 due to uneven compression of the sealing ring, which could affect radar penetration, thereby ensuring effective radar penetration. The front face 801 of the radar module 80 can be parallel to the radar plate 84. Furthermore, the front face 801 of the radar module 80 can be flat, facilitating casting and production.

[0104] Figure 40 Shown Figure 37 A top view of radar module 80 is shown.

[0105] like Figure 37 、 Figure 39 and Figure 40 As shown, the camera 10 includes a seal 81, which is clamped between the bottom wall 191 of the shell body 19 and the edge of the opening 88 in the longitudinal direction. In this way, the seal 81 is clamped between the bottom wall 191 of the shell body 19 and the edge of the opening 88 in the longitudinal direction, and the radar board 84 is installed on the radar cover 83, which can avoid the seal 81 in the direction of the radar cover 83 transmitting radar waves, thereby improving the effect of the radar board 84 passing through the radar cover 83. The seal 81 can be a sealing ring to improve the sealing performance. During the installation process, the front cover 16 of the camera 10 is turned upside down so that the front end face 801 of its radar module 80 in the second direction Q is facing upward, and then the seal 81 is pressed between the bottom wall 191 of the shell body 19 and the edge of the opening 88 in the longitudinal direction. As shown Figure 37 and Figure 39 As shown, the bottom wall 191 of the housing 19 is provided with a downwardly opening sealing groove 192. The edge of the opening 88 is provided with an upwardly opening sealing rib 881, and the seal 81 is retained in the sealing groove 192 and the sealing rib 881. In this way, the sealing groove 192 and the sealing rib 881 can improve the sealing reliability.

[0106] Figure 41 Shown Figure 40 The radar module 80 is shown in a cross-sectional view along line TT. Figure 40 and Figure 41 As shown, the radar module 80 includes a cavity wall 89 located within the radar cover 83. Cavity wall 89 includes an opening 88 and is sealed to the housing 19 via a seal 81, forming a sealed cavity 91. The radar panel 84 is installed within the sealed cavity 91, ensuring a secure seal and preventing water from entering the radar panel 84 and affecting its sealing function. Furthermore, the sealed cavity 91 is installed beneath the front cover 16 and is sealed by pressing the seal 81, providing a good seal. Furthermore, the sealed cavity 91 extends through the front cover 16 and the entire camera 10, ensuring a good seal. The radar panel 84 and the front sidewalls of the cavity wall 89 are parallel, which helps the radar panel 84 transmit radar waves.

[0107] Continue as Figure 40 and Figure 41 As shown, the radar panel 84 is located within a sealed cavity 91. The bottom wall 191 of the housing 19 covers the radome 83, forming an unsealed cavity 92 between the radome 83 and the cavity wall 89. A drainage trough 93 is provided within the radome 83. Thus, a drainage trough 93 for the radar module 80 is designed below the unsealed cavity 92 of the radome 83. The drainage holes prevent water accumulation. The left side wall of the radome 83 extends obliquely downward from top to bottom toward the cavity wall 89. The drainage trough 93 is located on the left side wall and extends from top to bottom along the left side wall to the bottom wall 191 of the radome 83, penetrating through the bottom wall 191. The right side wall of the radome 83 extends obliquely downward from top to bottom toward the cavity wall 89. The drainage trough 93 is located on the right side wall and extends from top to bottom along the right side wall to the bottom wall 191 of the radome 83, penetrating through the bottom wall 191. In this way, the accumulated water flowing down from the shell body 19 is facilitated to flow down from the left side wall of the drain trough 93 and / or the right side wall of the drain trough 93 .

[0108] Continue as Figure 37 and Figure 40 As shown, the top of the radome 83 has an upper opening, which is located inside the opening 88. The radome 83 is provided with a positioning structure 96, which is located outside the sealing member 81 and connected to the bottom wall 191 of the shell 19. This facilitates the alignment and connection of the radome 83 with the bottom wall 191 of the shell 19. Figure 37 and Figure 40 As shown, the cavity wall 89 is located in the middle of the radome 83 in the second direction Q. The positioning structure 96 includes positioning posts 961. These posts 961 are protruding from the upper edges of the radome 83 on both sides in the second direction Q, and mate with the housing 19. Thus, through the positioning of the posts 961, the radome 83 is aligned with the positioning grooves 193 of the bottom wall 191 of the housing 19 for assembly. Multiple posts 961 may be included, and detailed description is omitted here.

[0109] Figure 42 Shown Figure 37 An exploded view of the radar panel 84 and the radar cover 83 is shown. Figure 43 Shown Figure 36 The exploded view of the radome 83 and the shell 19 is shown.

[0110] like Figure 40 、 Figure 42 and Figure 43 As shown, the positioning structure 96 includes a longitudinally extending rib 97 protruding from the inner wall of the radome 83. The rib 97 includes a first rib 971 protruding from the front sidewall of the radome 83 and a second rib 972 located between the center of the rear sidewall of the radome 83 and the center of the rear sidewall of the cavity wall 89. The first rib 971 is located on the left and / or right side of the cavity wall 89, connected to the outer sidewall of the cavity wall 89, and extends longitudinally along the outer sidewall of the cavity wall 89. The second rib 972 protrudes from the rear sidewall of the radome 83 into the cavity wall 89. The rib 97 includes a screw hole extending longitudinally through the rib 97, which extends through the bottom wall 191 of the radome 83. The camera 10 includes a fixing member 98 for fixing the radome 83 to the housing 19. The fixing member 98 extends upward from the bottom wall 191 of the radome 83 through the screw hole to be fixedly connected to the housing 19. This improves the sealing between the cavity wall 89 within the radome 83 and the bottom wall 191 of the shell 19. The fixing member 98 may include multiple fixing members 98. The fixing member 98 may be a fixing post. The fixing member 98 may also be a screw. Examples are not given here one by one.

[0111] Continue as Figure 39 As shown, the bottom wall 191 of the housing 19 defines a cable hole 194, located above the opening 88 and communicating with the sealed cavity 91. The camera 10 includes a radar cable (not shown) connected to the radar board 84. This cable may include power and control signal lines. The radar cable (not shown) passes through the sealed cavity 91, through the cable hole 194, and into the hollow cavity 86 of the housing 19. This allows the radar cable (not shown) to be assembled on the front cover 16 of the camera 10 via the radar module 80. This transmits signals via the radar cable to control the radar module 80.

[0112] like Figure 42 As shown, the radar board 84 is mounted on the radar board support frame 82 using four screws 87. One end of a radar connecting cable (not shown) is plugged into the base of the radar board 84. This portion is then mounted downwardly on the bottom surface of the hollow cavity 86 of the radome 83 using two screws 94 and two positioning holes 95. The radar board 84 faces the front end 801 of the radar module 80 in the second direction Q, ensuring a uniform gap between the radar board 84 and the radome 83. Figure 42As shown, during the installation of the aforementioned fixings 98, before mounting the radar module 80 on the front cover 16 of the camera 10, it is necessary to pass the radar connecting cable (not shown) through the cable hole 194 below the front cover 16 of the camera 10. The radar cover 83 is designed with positioning posts 961 and ribs 97. These structural features allow for smooth pre-installation of the radar module 80 on the front cover 16 of the camera 10. Finally, the radar module 80 is secured to the front cover 16 of the camera 10 using three screws.

[0113] Figure 44 Shown Figure 43 A schematic diagram of the radome 83 and the shell 19 is shown.

[0114] like Figure 44 As shown, by plugging three rubber plugs 99 onto the fixing part 98 of the radar module 80, the leakage of the fixing part 98 is prevented from affecting the appearance. At this point, the radar module 80 of the camera 10 is installed, and the installation of other modules of the camera 10 can be carried out, which will not be described separately here.

[0115] Figure 45 Shown Figure 1 Schematic top view of the first lens assembly 13 and the second lens assembly 14 is shown. Figure 46 Shown Figure 1 The diagram shows a front view of the first lens assembly 13 and the second lens assembly 14.

[0116] like Figure 45 and Figure 46 As shown, the camera 10 may also include image sensors connected to the mainboard, a shared image processor for the first lens assembly 13 and the second lens assembly 14, a storage unit, and an image output interface. The image sensor utilizes the photoelectric conversion function of the photoelectric device to convert the light image on the photosensitive surface into an electrical signal proportional to the light image. The shared image processor converts and synthesizes the video images of the first lens assembly 13 and the second lens assembly 14, respectively. The storage unit is used to store the images.

[0117] Figure 47 Shown Figure 1 Schematic diagram of horizontal rotation of the mirror assembly shown. Figure 48 Shown Figure 1 The diagram shows the first lens assembly 13 in pitch rotation.

[0118] like Figure 47 and Figure 48As shown, after the light vertically enters the first window glass 1613 of the camera, passes through the reflector 151 and the first lens 132, and is able to illuminate the center of the image sensor (Complementary Metal-Oxide-Semiconductor, abbreviated as CMOS), it is the zero coordinate of the gimbal. That is, P=0, T=0. The downward rotation of the optical axis of the first lens 132 is the positive direction, and in the top view, the rightward rotation of the reflector 151 is the positive direction. When movement is required, the horizontal rotation angle of the image is twice the actual rotation angle of the reflector 151, and the rotation range is half of the horizontal field of view angle. The vertical rotation angle of the image is the angle of rotation of the rotation mechanism, and the range is the vertical field of view angle of the panoramic road. During the rotation process, the center of the detail road image is within the field of view of the panoramic road. Continue as Figure 48 As shown, when the first lens 132 rotates from a maximum pitch angle d to a minimum pitch angle c, and the reflector 151 remains stationary, the pitch intersection trajectory of the optical axis of the first lens 132 and the reflector 151 deviates from the center of the reflective surface of the reflector 151. The line connecting the point where the optical axis of the first lens 132 intersects with the reflector 151 at the maximum pitch angle d and the point where the optical axis of the first lens 132 intersects with the reflector 151 at the minimum pitch angle c divides the reflector 151 into a first area 1513 and a second area 1514. The area of ​​the first area 1513 is larger than that of the second area 1514. In this way, light can be more easily incident through the first area 1513.

[0119] Figure 49 Shown Figure 1 The enlarged schematic diagram of the picture taken by the second lens assembly is shown.

[0120] like Figure 49 As shown, the camera 10 is configured to determine a pan angle and a tilt angle in response to detecting the world coordinates of at least one subject, so that the subject is positioned in the center of the image captured by the camera 10 at the pan and tilt angles. Thus, compared to the PT camera 10 in the related art, the spherical camera 10, due to its large size and relatively slow rotation speed, may miss the target during rotation. The rotation may also cause overall camera 10 shaking, resulting in blurred images. In the embodiment of the present application, the reflector assembly and the first lens assembly 13, located on the optical path of light from the monitored area incident on the first lens assembly 13, are each smaller than the entire camera 10. This reduces overall camera 10 shaking caused by rotation, resulting in higher image clarity.

[0121] continue Figure 49 As shown, a rectangular frame is drawn in the video image on the display as the interest frame through an input device such as a mouse, thereby determining the center coordinates of the drawn frame ( ), as the coordinates of the target of interest; determine the size of the interest box as Assuming the current focal length is f and the vertical resolution is H, the target focal length after the interest frame is enlarged can be estimated for:

[0122]

[0123] Then the device's pan / tilt will drive the camera 10 to rotate until the center of the image coincides with the center of interest. At the same time, the camera 10 zooms until the diagonal field of view coincides with the field of view of interest. If the length of the frame is not drawn when drawing the frame, that is, the interest frame is a point, If is 0, the PTZ will rotate, but the camera 10 will not zoom. >0 , but If the focal length is smaller than the maximum magnification of the device, it will be magnified to the maximum magnification.

[0124] Figure 50 Shown Figure 1 The diagram shows the horizontal rotation angle and the tilt rotation angle of the camera 10.

[0125] like Figure 50 As shown, the camera 10 is configured to: convert the world coordinates into spherical coordinates; determine the horizontal rotation angle according to the spherical coordinates and pitch angle The horizontal rotation angle is the absolute value of the inverse tangent function of the ratio of the horizontal to the vertical in the world coordinate. The pitch rotation angle is the absolute value of the inverse sine function of the vertical in the world coordinate. Where, P (pan, horizontal rotation angle). T (tile, vertical rotation angle). Horizontal rotation angle and pitch angle The detailed calculation process of is as follows. Figure 50 As shown, the parameters of the camera 10 include internal parameters and external parameters. The internal parameters include distortion parameters and internal parameter matrix, which represent the properties of the camera 10 itself and will not be changed by external factors. Only the zoom camera 10 will change when the zoom is changed.

[0126]

[0127] in, As internal reference, is the current focal length in millimeters, dx and dy are the CMOS pixel width and height in millimeters, and is the horizontal resolution of the image, in pixels. Furthermore, the external parameter is a matrix that contains the displacement [T] and attitude [R], which is what we usually call pose.

[0128] Assuming that the displacement T is 0 and the rotation order is X, Y, Z, the external parameter matrix for:

[0129]

[0130]

[0131]

[0132]

[0133] The extrinsic parameters for camera 10 are generated as follows: The model is built using a Cartesian coordinate system by default, with the center of the camera 10's CMOS image sensor at zero. When there are only two dimensions, x and y, the image is assumed to be on the plane at z = 1. The coordinate system used by the dome camera uses the negative Y-axis as the zero position, so it must be rotated to the negative Y-axis during initialization.

[0134] To this end, initialize the external parameter matrix as:

[0135]

[0136] After initialization, the camera is rotated around the X-axis and Z-axis according to the PT value to generate a set of external parameter matrices for:

[0137]

[0138] The above coordinate conversion is as follows: After obtaining the internal parameters, distortion parameters and external parameters, the coordinate conversion can be performed. The image coordinate conversion process to the PT coordinate of the ball machine is as follows:

[0139] PT to 3D (world coordinates):

[0140]

[0141] 3D to 2D:

[0142]

[0143] 2D to 3D:

[0144]

[0145]

[0146]

[0147] 3D to PT coordinates:

[0149] In this way, the precise conversion between the target of the second lens assembly 14 and the center of the first lens assembly 13 can be achieved. The movement of the reflector 151 and the camera 10 inside the device allows the first lens assembly 13 to be captured within the field of view of the second lens assembly 14, achieving rapid capture with minimal jitter during the movement, ensuring clear captured images.

[0150] Figure 51 Shown Figure 1 The diagram shows the linkage between the first lens assembly 13 and the second lens assembly.

[0151] Combine Figure 7 and Figure 5 and Figure 51 As shown, the main body housing 18 includes a first housing sidewall 183 and a second housing sidewall 184 that are opposite to each other in a first direction W. The front cover 16, covering the front side of the main body housing 18, includes a rectangular first through-hole 161. A first longitudinally extending side of the first through-hole 161 is adjacent to the first housing sidewall 183 relative to the second housing sidewall 184 and is spaced a first distance from the first housing sidewall 183. A second longitudinally extending side of the first through-hole 161 is spaced a second distance from the second housing sidewall 184, wherein the first distance is less than the second distance. The first lens assembly 13 is disposed in an area within the main body housing 18 near the second housing sidewall 184. The camera 10 is configured such that when the reflector 151 rotates from the first horizontal boundary position to the second horizontal boundary position and the first lens 132 remains stationary, the horizontal intersection trajectory 22 of the optical axis of the first lens 132 and the reflector 151 deviates from the center 1512 of the reflective surface. When the first lens 132 rotates from the first pitch boundary position 133 to the second pitch boundary position 134 and the reflector 151 remains stationary, the pitch intersection trajectory of the optical axis of the first lens 132 and the reflector 151 deviates from the center of the reflective surface. In this way, the horizontal intersection trajectory 22 of the optical axis of the first lens 132 and the reflector 151 is not colinear with the center 1512 of the reflective surface of the reflector 151, thereby realizing the horizontal rotation of the reflector 151 and the pitch rotation of the first lens 132 to complete the image capture of the monitored area, and also realizing the linkage of the first lens assembly 13 and the second lens assembly 14 and the miniaturization of the camera. In the embodiment of the present application, the horizontal rotation of the reflector 151 is set, the horizontal rotation range is small, and the rotation is fast. Among them, the rotation shaft of the horizontal rotation motor extends vertically, and the rotation shaft of the pitch rotation motor 41 extends horizontally; the central axis of the rotation shaft of the horizontal rotation motor is not coplanar with the central axis of the rotation shaft of the pitch rotation motor 41.

[0152] Figure 52 Shown Figure 51 FIG. 1 is a schematic diagram of image partitioning of the second lens assembly 14 shown.

[0153] like Figure 51 and Figure 52 As shown, the second lens assembly 14 includes a second lens 142, which includes a second lens element (not shown) and a second image sensor (not shown). The camera 10 is configured to, in response to an object captured by the second lens 142, determine a first control instruction for adjusting the horizontal angle of the reflector 151 and / or a second control instruction for adjusting the pitch angle of the first lens 132 based on a mapping matrix between the second lens 142 and the first lens 132. Accordingly, in response to the first control instruction, the panning mechanism pans, causing the reflector 151 to adjust its horizontal angle; and / or, in response to the second control instruction, the pitch drive mechanism tilts, causing the first lens 132 to adjust its pitch angle, so that when the camera 10 is at the P and T coordinates, the object is at a predetermined position in the image captured by the first lens 132. In this way, the first and second lenses 132 and 142 work in tandem to adjust the horizontal and pitch angles of the camera 10.

[0154] The second lens assembly 14 is located below the reflector 151, and its field of view overlaps that of the first lens assembly 13. The camera 10 is configured such that the horizontal angle of the reflector 151 is the value of the inverse tangent function of the P coordinate, and the pitch angle is the value of the inverse tangent function of the T coordinate. This allows the horizontal and pitch angles to be obtained and calculated in real time.

[0155] Continue as Figure 51 As shown, the linkage between the second lens assembly 14 and the first lens assembly 13 includes two types: forward and reverse. Forward linkage: At any point M in the image of the second lens assembly 14, a set of PT values ​​for the first lens assembly 13 can be found. The PT value is the sum of the P and T values. When the first lens assembly 13 moves to this PT coordinate, the image center N coincides with point M. Reverse linkage: At any PT, the center point N of the first lens assembly 13 can be found to coincide with point M in the image of the second lens assembly 14. The PT coordinate is the sum of the P and T coordinates.

[0156] like Figure 52As shown, the camera 10 is configured to: acquire an image containing an object using the second lens assembly 14. Determine the position of the object in the image. In response to the mapping matrix between the second lens assembly 14 and the first lens assembly 13, determine the P coordinate for driving the reflector 151 and the T coordinate for driving the first lens 132 according to the position, so that when the camera 10 is at the P coordinate and the T coordinate, the object is confined to a preset area where the first lens assembly 13 captures the image. Adjust the horizontal angle of the reflector 151 according to the P coordinate. And adjust the pitch angle of the first lens 132 according to the T coordinate. Further, the second lens assembly 14 is located below the reflector 151, and the field of view of the second lens assembly 14 covers the field of view of the first lens assembly 13. The camera 10 is configured to respond to a mapping matrix corresponding to a preset area; the preset area is one of a plurality of lateral areas, and the plurality of lateral areas are obtained by horizontally dividing the captured image of the first lens assembly 13 according to the parallax between the second lens assembly 14 and the first lens assembly 13, and the larger the parallax between the second lens assembly 14 and the first lens assembly 13, the smaller the corresponding preset area, and the mapping matrix is ​​determined based on the positions of at least 4 points on the area boundary line of each lateral area in the plurality of lateral areas, and the position of the alignment point when the second lens 142 is aligned with the position of the at least 4 points; the at least 4 points are respectively at least two columns with two points in each column; the P coordinate and the T coordinate are determined based on the corresponding mapping matrix and position.

[0157] like Figure 52 As shown, a virtual plane is created for the first lens assembly 13. When the PT of the camera 10 is (0, 0), the optical center is perpendicular to the plane, and the distance between the plane and the camera 10 is L. Then, for each set of PT values, the coordinates of the image center aligned with the virtual plane are ( , ) =TanP, =TanT. The monitoring range of the camera 10 is mostly the ground, so it is generally installed at a depression angle. Because the second lens assembly 14 is directly below the reflector 151, it can be considered to be in the horizontal direction, and the second lens assembly 14 and the first lens assembly 13 will not deviate due to displacement. However, the deviation in the vertical direction cannot be ignored. The closer the object distance, the greater the parallax produced by the two cameras 10. To address this problem, a strategy of layering the panoramic image is adopted: the panoramic image is divided into n preset areas from top to bottom, with the vertical coordinates of the first and last rows being Y0 and Yn respectively, and dividing lines Y1, Y2, ..., Yn-1 are added. Each dividing line divides a preset area below into half.

[0158] During the calibration process, if you randomly select a point on the left and right halves of each horizontal line, a total of 2n+2 points will be generated, which are used as calibration points. Let the first lens assembly 13 adjust the pan / tilt coordinate PT so that the image center of the camera 10 is aligned with the 2n+2 points in the second lens assembly 14. Figure 52 As shown, there can be four preset areas. The coordinates of four points on the edge of each preset area in the image plane R of the second lens assembly 14, such as point A (XRA, YRA), and the virtual coordinates of four points on the corresponding virtual plane G, such as point A (XGA, YGA), can form a mapping relationship as shown in Table 1.

[0159] Table 1 shows that four sets of point pairs can form a mapping relationship

[0160]

[0161] There is a relationship G = H × R, where H is the homography matrix from R to G of camera 10. The homography matrix size is 3 rows and 3 columns, so the relationship is:

[0162]

[0163] Substituting the four coordinate pairs (as shown in Table 1) into the equation, the parameters of the homography matrix H can be solved. This yields the mapping relationship between the second lens assembly 14 and the virtual plane in the preset region A. Preset regions 1 through n correspond to matrices H1 through Hn.

[0164] The homography matrix is ​​a 3×3 matrix with a total of 9 parameters. The specific parameters in the homography matrix H are as follows:

[0165]

[0166] However, the coordinates used in the embodiment of the present application are homogeneous coordinates, which are scale-invariant. In practice, only 8 parameters need to be solved. For example, there is a set of points and , then there exists a homogeneous relation: and

[0167] First, list the homography transformation relationship:

[0168]

[0169] The homography matrix is ​​proposed as factors and import them into the homogeneous matrix of points,

[0170]

[0171] The relationship between the two coordinates is expanded as follows:

[0172]

[0173] The above formula The variables are eliminated and simplified to:

[0174]

[0175] Will Substitute into We get:

[0176]

[0177] One set of coordinate pairs can list two equations, and four sets can list eight equations. This means that eight unknowns can be solved. In actual use, first find the area and the corresponding matrix H based on the coordinate Y of the second lens assembly 14R. Then substitute the coordinates of the point in the camera into G = H × R to obtain the virtual coordinates ( , ), and then we can find ∠P=ATan( ) and ∠T=ATan( ). In this way, the first lens assembly 13 completes the capture by vertical rotation and horizontal galvanometer rotation.

[0178] For example, in the second lens assembly 14, the resolution is 1920 1080, a point in the second partition of the image ( , ), that is, H=H2. The virtual coordinates are obtained by the following formula and :
