Description

Technical Field

[0001] This application belongs to the technical field of imaging devices, and particularly relates to a camera. Background Art

[0002] As one of the imaging devices, cameras have now been widely used in various fields such as transportation and medical care. For example, in the transportation field, cameras are used for road monitoring; at the same time, cameras can also be used in many aspects of people's work, life, and entertainment, such as shooting videos with cameras to record life, etc.

[0003] Taking road monitoring as an example, using cameras to monitor road traffic flow, track target vehicles, etc. requires the camera to have a large shooting range in the vertical direction so as to be able to capture images in a large range. The field of view angle of the lens assembly of existing cameras in the vertical direction is small and cannot meet the usage requirements. Usually, a motor is used to drive the lens assembly to rotate up and down, so as to obtain a large shooting range in the vertical direction. However, during the process of the motor driving the lens assembly to rotate up and down, a large shooting range in the vertical direction cannot be obtained in real time, so there are blind spots in the field of view during monitoring. Summary of the Utility Model

[0004] The purpose of the embodiments of this application is to provide a camera that can solve the problem that the existing camera cannot obtain a large shooting range in the vertical direction in real time, resulting in blind spots in the field of view.

[0005] To solve the above technical problems, this application is implemented as follows:

[0006] The embodiments of this application provide a camera, including:

[0007] A housing, the housing having a shooting window;

[0008] A first lens assembly and a second lens assembly, both the first lens assembly and the second lens assembly are disposed in the accommodation cavity of the housing, the incident light surface of the first lens assembly and the incident light surface of the second lens assembly both face the shooting window, the first lens assembly has a first field of view area, the second lens assembly has a second field of view area, and the first field of view area and the second field of view area partially overlap in the vertical direction.

[0009] In the embodiment of the present application, a first lens assembly and a second lens assembly are arranged in the accommodation cavity of the housing. The light incident surfaces of the first lens assembly and the second lens assembly both face the shooting window of the housing, and both obtain incident light through the shooting window. The first field of view area of the first lens assembly and the second field of view area of the second lens assembly partially overlap in the vertical direction. By increasing the number of lens assemblies, the field of view area of the first lens assembly and the field of view area of the second lens assembly partially overlap in the vertical direction, and they cooperate to work, thereby increasing the field of view angle (i.e., the vertical field of view angle) of the camera in the vertical direction. During the shooting process of the camera, the camera can obtain a larger shooting range in the vertical direction in real time, thereby preventing the existence of a blind area of vision. At this time, after the first lens assembly and the second lens assembly are imaged respectively, the pictures are stitched to obtain an image with a better effect in a larger range.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0022] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0023] The camera provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0024] As Figures 1 to 6 shown, an embodiment of the present application discloses a camera, which includes a housing 100, a first lens assembly 200, and a second lens assembly 300.

[0025] The housing 100 has a shooting window 110. Optionally, the shooting window 110 can be an opening structure or a light-transmitting structure, and the embodiments of the present application do not make specific limitations thereto.

[0026] Both the first lens assembly 200 and the second lens assembly 300 are disposed in the accommodation cavity of the housing 100, and the housing 100 can protect the first lens assembly 200 and the second lens assembly 300. The light incident surfaces of the first lens assembly 200 and the second lens assembly 300 both face the shooting window 110 to obtain light in the external environment. The first lens assembly 200 has a first field of view area, and the second lens assembly 300 has a second field of view area. The first field of view area and the second field of view area partially overlap in the vertical direction. Optionally, the first lens assembly 200 and the second lens assembly 300 can be arranged in the vertical direction (that is, the first lens assembly 200 and the second lens assembly 300 can be completely directly opposite or partially directly opposite in the vertical direction).

[0027] In the embodiment of the present application, a first lens assembly 200 and a second lens assembly 300 are disposed in the accommodation cavity of the housing 100. The light incident surfaces of the first lens assembly 200 and the second lens assembly 300 both face the shooting window 110 of the housing 100. The two obtain incident light through the shooting window 110. A first field of view region of the first lens assembly 200 and a second field of view region of the second lens assembly 300 partially overlap in the vertical direction. By increasing the number of lens assemblies, the first field of view region of the first lens assembly 200 and the second field of view region of the second lens assembly 300 partially overlap in the vertical direction, and the two cooperate to work, thereby increasing the field of view angle (i.e., the vertical field of view angle) of the camera in the vertical direction. During the shooting process of the camera, the camera can obtain a relatively large shooting range in the vertical direction in real time, thereby preventing the existence of a blind spot of view. At this time, the first lens assembly 200 and the second lens assembly 300 respectively image and then perform picture stitching to obtain an image with a good effect within a relatively large range. Therefore, this solution can solve the problem that the existing camera cannot obtain a relatively large shooting range in the vertical direction in real time, resulting in a blind spot of view.

[0028] In addition, since this solution avoids using a motor to drive the lens to rotate in the vertical direction, it not only saves the motor, but also saves the driving circuit of the motor, which is beneficial to reducing the manufacturing cost and waterproof cost of the camera.

[0029] In an optional embodiment, the overlapping region of the first field of view region of the first lens assembly 200 and the second field of view region of the second lens assembly 300 in the vertical direction is the third field of view region. Since the light incident surface of the existing lens is usually a circular structure, correspondingly, the contour line of the field of view region of the lens is also a circular contour line. When the vertical field of view angle corresponding to the third field of view region is less than the preset angle, it indicates that the overlapping region of the first field of view region and the second field of view region is small. At this time, the size of the joint between the first field of view region and the second field of view region in the horizontal direction is small, and the horizontal field of view angle corresponding to the third field of view region is small, and it is easy to have a shooting blind spot; based on this, optionally, the vertical field of view angle corresponding to the third field of view region is greater than or equal to the preset angle, so that the size of the joint between the first field of view region and the second field of view region in the horizontal direction is large, thereby increasing the field of view angle corresponding to the third field of view region, avoiding the existence of a shooting blind spot, and further improving the integrity of the shooting picture of the camera.

[0030] It should be noted that the above preset angle can be a specific value or a value range, and can be specifically selected according to actual needs. The embodiment of the present application does not make specific limitations on this.

[0031] Optionally, the difference between the sum of the vertical field of view angle θ1 corresponding to the first field of view region and the vertical field of view angle θ2 corresponding to the second field of view region and the vertical field of view angle θ3 corresponding to the third field of view region can be greater than or equal to 90°, that is, the vertical field of view angle of the camera is greater than or equal to 90°, so as to obtain a larger shooting range, thereby improving the imaging effect.

[0032] Optionally, the vertical field of view angle θ3 corresponding to the third field of view region needs to satisfy the following formula:

[0033] θ3≥ζ(θ1 + θ2),

[0034] where ζ is a coefficient between 0 and 1, and the specific value of ζ can be determined according to the required vertical field of view angle of the camera, and the embodiments of the present application do not make specific limitations on this.

[0035] In another alternative embodiment, the horizontal plane where the center of the accommodation cavity of the housing 100 is located is the first plane 610, and the vertical plane where the center of the accommodation cavity of the housing 100 is located is the second plane 620. The light incident surfaces of the first lens assembly 200 and the second lens assembly 300 are both located in the same quadrant formed by the first plane 610 and the second plane 620, that is, the first plane 610 and the second plane 620 form four quadrants, and the light incident surfaces of the first lens assembly 200 and the second lens assembly 300 are both located in one of the quadrants. The light incident surface of the first lens assembly 200 is close to the first plane 610. At this time, the light incident surface of the second lens assembly 300 is close to the second plane 620, and the angle θ4 between the optical axis of the first lens assembly 200 and the first plane is greater than 0°, that is, the optical axis of the first lens assembly 200 is inclined downward relative to the first plane 610. In this solution, the angle between the optical axis of the first lens assembly 200 and the optical axis of the second lens assembly 300 is less than 90°, so that the first field of view region and the second field of view region have a larger overlapping field of view region within the same quadrant (90° range), thereby ensuring that the camera has a sufficiently large field of view angle, which is beneficial to expanding the shooting range of the camera, thereby improving the picture effect obtained by the camera. Of course, the optical axis of the first lens assembly 200 can also be parallel to the first plane 610.

[0036] Optionally, the angle between the optical axis of the second lens assembly 300 and the second plane 620 can be greater than 0°, and the optical axis of the second lens assembly 300 is inclined relative to the second plane 620, which can further reduce the angle between the optical axis of the first lens assembly 200 and the optical axis of the second lens assembly 300, so as to further increase the third field of view region.

[0037] In an alternative embodiment, since the camera is usually set at a relatively high position and takes a downward view, for example, it is set above a road. Therefore, the light incident surfaces of the first lens assembly 200 and the second lens assembly 300 are both located below the first plane 610 to facilitate meeting the shooting requirements. In this case, the field-of-view regions of the first lens assembly 200 and the second lens assembly 300 within their respective quadrants are the effective field-of-view regions of the camera, and the field-of-view regions above the first plane 610 do not fall within the scope of road monitoring. Of course, adjustments can also be made according to actual usage requirements, and the light incident surfaces of the first lens assembly 200 and the second lens assembly 300 can both be set above the first plane 610, and at this time the camera captures the image above it.

[0038] Since the light incident surface of an existing lens is usually a circular structure, correspondingly, the contour line of the field-of-view region of the lens is also a circular contour line. When the light incident surface of the first lens assembly 200 and the first field-of-view region are both located below the first plane 610, there is likely to be a shooting blind area in the part of the first field-of-view region close to the first plane 610. Therefore, in an alternative embodiment, a part of the first field-of-view region of the first lens assembly 200 is located above the first plane 610, that is, the first field-of-view region is distributed in different quadrants (in the vertical direction, the vertical field-of-view angle corresponding to the part of the first field-of-view region located above the first plane 610 is θ5). At this time, the size of the part of the first field-of-view region distributed below the first plane 610 and close to the first plane 610 in the horizontal direction is relatively large, which is beneficial to increasing the field-of-view angle corresponding to the effective field-of-view region of the camera, thereby avoiding the appearance of a shooting blind area.

[0039] In another alternative embodiment, a part of the second field-of-view region is located on the side of the second plane 620 away from the light incident surface of the second lens assembly 300 (in the horizontal direction, the vertical field-of-view angle corresponding to the part of the second field-of-view region located on the side of the second plane 620 away from the light incident surface of the second lens assembly 300 is θ6), that is, the second field-of-view region is distributed in different quadrants below the first plane 610. Similarly, when the size of the part of the second field-of-view region of the second lens assembly 300 close to the second plane 620 within the quadrant where the second lens assembly 300 is located in the horizontal direction is relatively large, this can increase the field-of-view angle corresponding to the effective field-of-view region of the camera to avoid the existence of a shooting blind area. Of course, the light incident surface of the second lens assembly 300 and the second field-of-view region can also be located in the same quadrant.

[0040] It should be noted that the above-mentioned first field of view area and second field of view area are both distributed in different quadrants, and the two are used to increase different parts of the effective field of view area of the camera. For example, when the camera is set above the road, the first field of view area is distributed in different quadrants to increase the part of the effective field of view area of the camera far from the road surface, while the second field of view area is distributed in different quadrants to increase the part of the effective field of view area of the camera close to the road surface.

[0041] In another alternative embodiment, the camera further includes a bracket 400 for connecting to the basic component where the camera is set. The housing 100 includes a first housing 120 and a second housing 130 that are detachably connected to facilitate the installation of structures such as the first lens assembly 200 and the second lens assembly 300 in the accommodation cavity. The first housing 120 and the second housing 130 enclose the accommodation cavity, and the first housing 120 and the second housing 130 are hermetically fitted to prevent moisture in the environment from entering the accommodation cavity, thereby protecting the structures such as the first lens assembly 200 and the second lens assembly 300 arranged in the accommodation cavity. Optionally, the first housing 120 and the second housing 130 are hermetically connected through a first sealing member 160 to improve the sealing performance in the accommodation cavity. The first housing 120 is provided with a shooting window 110. The first housing 120 has a first mating surface 121 that contacts the second housing 130. The vertical plane where the center of the accommodation cavity is located is the second plane 620. The first mating surface 121 is inclined with respect to the second plane 620. The second housing 130 is connected to the bracket 400, that is, the first housing 120 is arranged on the second housing 130. At this time, the first housing 120 does not need to be connected to the bracket 400. This solution adopts such a setting method, which can improve the disassembly and assembly flexibility and convenience of the camera. For example, after the first housing 120 and the second housing 130 are assembled (the first lens assembly 200 and the second lens assembly 300 have been installed in the accommodation cavity), they can be installed on the bracket 400, or the second housing 130 can be installed on the bracket 400 first, then the first lens assembly 200 and the second lens assembly 300 are assembled, and finally the first housing 120 is installed on the second housing 130; in addition, during disassembly and maintenance, it is not necessary to disassemble the second housing 130 from the bracket 400, and only the first housing 120 can be disassembled. Of course, the first mating surface 121 and the second plane 620 can also coincide or be parallel.

[0042] Optionally, the angle between the optical axis of the first lens assembly 200 and the first mating surface 121 can be an acute angle or an obtuse angle; or, in other embodiments, the optical axis of the first lens assembly 200 is perpendicular to the first mating surface 121 (that is, the included angle between the optical axis of the first lens assembly 200 and the first mating surface 121 is θ7). With the first housing 120 having such a structure, the structural design of the mold for manufacturing the first housing 120 can be simplified.

[0043] In a further optional embodiment, the first housing 120 is rotatably connected to the bracket 400. The camera further includes a driving member 500, which can be a driving device such as a motor, and no specific limitation is made here. The driving member 500 is disposed on the second housing 130. The output shaft of the driving member 500 is connected to the bracket 400. The driving member 500 can drive the first housing 120, the second housing 130, the first lens assembly 200, and the second lens assembly 300 to rotate relative to the bracket 400 in a horizontal plane. That is, the output shaft of the driving member 500 is fixedly connected to the bracket 400. At this time, when the driving member 500 outputs a driving force, the main body of the driving member 500 rotates relative to the output shaft, and the main body of the driving member 500 is connected to the second housing 130, so the main body of the driving member 500 will drive the second housing 130 to rotate together. By providing the driving member, when installing the camera, there is no need to deliberately adjust the viewing angle of the camera to the required shooting direction. After the installation is completed, the driving member 500 can be used for driving adjustment to improve the installation flexibility of the camera; when the camera is installed on the installation base, once the shooting range of the camera within the horizontal range changes, the driving member 500 can be used to drive the housing 100, the first lens assembly 200, and the second lens assembly 300 to rotate together in the horizontal plane, so that the viewing angle of the camera rotates to the required direction within the horizontal plane, thereby meeting the shooting requirements. Therefore, this is beneficial to improving the shooting flexibility and application range of the camera. Of course, the driving member can also be not provided, and the viewing angle of the camera can be adjusted manually in the horizontal plane by rotating the camera.

[0044] Optionally, the bracket 400 includes a first frame body 410 and a second frame body 420 that are detachably connected. The first frame body 410 is used to connect to the installation base. One of the second frame body 420 and the second housing 130 is provided with a hanging convex portion 421, and the other is provided with an annular groove 131. The annular groove 131 is engaged with the hanging convex portion 421, and the second housing 130 can rotate relative to the second frame body 420.

[0045] Optionally, since the optical axes of the first lens assembly 200 and the second lens assembly 300 intersect or are skew, they cannot be mounted on the inner surface of the housing 100 using the same mounting bracket; therefore, the first lens assembly 200 and the second lens assembly 300 need to be mounted on the inner surface of the housing 100 through different mounting brackets respectively, but interference is likely to occur between the two mounting brackets; based on this, in still another optional embodiment, the inner surface of the housing 100 is provided with a first connecting column 140 and a second connecting column 150. Optionally, the first connecting column 140 and the second connecting column 150 and the housing of the housing 100 can be an integral structure or a split structure, and then connected by means such as bonding, and no specific limitation is made here.

[0046] The first lens assembly 200 includes a first lens 210 and a first circuit board 220. The first lens 210 is disposed on the first circuit board 220. Structures such as a first image sensor may be provided on the first circuit board 220. The first image sensor is used to receive the optical signal transmitted by the first lens 210. The first circuit board 220 is connected to the first connecting post 140, and the central axis of the first connecting post 140 is parallel to the optical axis of the first lens 210. The second lens assembly 300 includes a second lens 310 and a second circuit board 320. The second lens 310 is disposed on the second circuit board 320. Structures such as a second image sensor may be provided on the first circuit board 220. The second image sensor is used to receive the optical signal transmitted by the second lens 310. The second circuit board 320 is connected to the second connecting post 150, and the central axis of the second connecting post 150 is parallel to the optical axis of the second lens 310. In this solution, both the first lens assembly 200 and the second lens assembly 300 are directly fixed to the housing, which can avoid using a mounting bracket to fixedly connect with the housing 100. This is beneficial to reducing the layout difficulty of the first lens assembly 200 and the second lens assembly 300 in the accommodation cavity. Moreover, usually the optical axis of the lens is perpendicular to the circuit board, while in this solution, the central axis of the first connecting post 140 is parallel to the optical axis of the first lens 210, and the central axis of the second connecting post 150 is parallel to the optical axis of the second lens 310. This facilitates the connection between the first circuit board 220 and the first connecting post 140, and the connection between the second circuit board 320 and the second connecting post 150.

[0047] Optionally, the first connecting post 140 is provided with a first connecting hole, and the first circuit board 220 is threadedly connected to the first connecting post 140 through a first fastener. The second connecting post 150 is provided with a second connecting hole, and the second circuit board 320 is threadedly connected to the second connecting post 150 through a second fastener, that is, a detachable connection method is adopted to facilitate the disassembly and assembly of the first lens assembly 200 and the second lens assembly 300. Of course, at least one of the first circuit board 220 and the second circuit board 320 may also be connected to the first connecting post 140 and the second connecting post 150 by means of welding or the like.

[0048] Optionally, the number of at least one of the first connecting post 140 and the second connecting post 150 may be at least two. Each first connecting post 140 may be disposed around the first lens 210 to increase the connection area between the housing 100 and the first circuit board 220, thereby enhancing the connection firmness and stability of the first lens assembly 200. Each second connecting post 150 may be disposed around the second lens 310 to increase the connection area between the housing 100 and the second circuit board 320, thereby enhancing the connection firmness and stability of the second lens assembly 30,

[0049] Optionally, the shooting window 110 may be a light-transmitting structure. In this case, both the first lens 210 and the second lens 310 are located in the accommodation cavity. Or, in another embodiment, the shooting window 110 may be a continuous avoidance opening, that is, the first lens 210 and the second lens 310 obtain incident light through the same avoidance opening. Or, in other embodiments, the shooting window 110 includes a first light-transmitting hole 111 and a second light-transmitting hole 112 arranged at intervals. The light-incident surface of the first lens 210 faces the first light-transmitting hole 111, and a part of the first lens 210 extends into the first light-transmitting hole 111 and is hermetically fitted with the inner wall of the first light-transmitting hole 111. The light-incident surface of the second lens 310 faces the second light-transmitting hole 112, and a part of the second lens 310 extends into the second light-transmitting hole 112 and is hermetically fitted with the inner wall of the second light-transmitting hole 112. During the installation process of the first lens 210 and the second lens 310, both the first light-transmitting hole 111 and the second light-transmitting hole 112 can provide a guiding function. When the circumferential surface of the first lens 210 is hermetically fitted with the inner wall of the first light-transmitting hole 111, and the circumferential surface of the second lens 310 is hermetically fitted with the inner wall of the second light-transmitting hole 112, this can improve the installation stability of the first lens 210 and the second lens 310. In addition, the light-incident surfaces of the first lens 210 and the second lens 310 are respectively exposed through the first light-transmitting hole 111 and the second light-transmitting hole 112, and ambient light directly contacts the light-incident surfaces of the first lens 210 and the second lens 310, which can reduce light loss and thus improve the light utilization rate of the first lens 210 and the second lens 310.

[0050] Optionally, the first lens 210 and the inner wall of the first light-transmitting hole 111 may be hermetically fitted through a second sealing member 230 to improve the sealing performance at the first light-transmitting hole 111. The second lens 310 and the inner wall of the second light-transmitting hole 112 may be hermetically fitted through a third sealing member 330 to improve the sealing performance at the second light-transmitting hole 112, thereby preventing impurities such as dust from entering the accommodation cavity of the housing 100 and improving the sealing performance of the housing 100.

[0051] Optionally, at least one of the above-mentioned first sealing member 160, second sealing member 230, and third sealing member 330 may be an O-ring. Of course, it may also be other types of sealing structures, and the embodiments of the present application do not make specific limitations in this regard.

[0052] Optionally, when the installation space in the accommodation cavity permits, a fixing bracket may be arranged in the accommodation cavity to fix the first circuit board 220 or the second circuit board 320 (preferably the circuit board with a larger load), thereby improving its stability.

[0053] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the spirit of the present application and the scope protected by the claims, and all of them fall within the protection scope of the present application.
