Description

Technical Field

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

[0002] Panoramic and wide-angle videos captured by shooting devices with multiple lens modules have been widely used in industries such as industry, transportation, shopping malls, banks, public security, and smart residential communities, becoming one of the important means of security management.

[0003] Currently, the arrangement of multiple lens modules in a shooting device requires a relatively large space, resulting in a relatively large size of the entire shooting device, which is inconvenient to install and carry. Summary of the invention

[0004] The embodiments of the present application provide a camera and a dome camera to improve the problem of large size of existing camera devices.

[0005] In a first aspect, an embodiment of the present application provides a photographing device, comprising a bracket and a plurality of lens modules arranged circumferentially;

[0006] The multiple lens modules are installed on the bracket, and each lens module includes a base and a camera part connected to and perpendicular to the base. The bases of each two adjacent lens modules are close to or abut against each other, and the projection of the base of each lens module along the optical axis direction of the camera part is at least partially blocked by the base of at least one lens module adjacent to each lens module.

[0007] In the above technical solution, multiple lens modules are installed on a bracket, and the bracket plays a role in fixing each lens module. The bases of each two adjacent lens modules are close to or abut against each other, and the projection of the base of each lens module along the optical axis direction of the camera unit at least partially blocks the base of at least one lens module adjacent to it, that is, each lens module partially overlaps with at least one lens module adjacent to it in space, reducing the space occupied by all lens modules, effectively reducing the volume of the entire shooting device, and facilitating installation and carrying.

[0008] In addition, the photographing device of the embodiment of the present application also has the following additional technical features:

[0009] In some embodiments of the present application, the optical axes of all camera parts in the multiple lens modules are located in the same plane.

[0010] In the above technical solution, the optical axes of all camera units are located in the same plane, further reducing the space occupied by all lens modules.

[0011] In some embodiments of the present application, the plurality of lens modules are distributed on the bracket around a first reference line, and the optical axis of each camera unit is perpendicular to the first reference line;

[0012] All bases in the multiple lens modules form a polygon, the optical axis of each base is located on one side of the polygon, and according to the circumferential order of the circle with the first reference line as the axis, the projection of the base of the previous lens module along the optical axis direction of the camera part is at least partially blocked by the base of the next lens module adjacent to the previous lens module.

[0013] In the above technical solution, all lens modules are distributed on the bracket around the first reference line, the optical axis of each camera unit is perpendicular to the first reference line, and all bases form a polygonal structure with a compact structure. While meeting the requirements of 360-degree panoramic shooting, the space occupied by all lens modules is effectively reduced. In addition, this structure can shorten the baseline between lens modules (the distance between lens modules), thereby reducing the ghosting between lens modules.

[0014] In some embodiments of the present application, the polygon is a regular polygon.

[0015] In the above technical solution, the optical axes of all camera units form a regular polygonal structure, making the structure more compact.

[0016] In some embodiments of the present application, the plurality of lens modules are distributed on partially adjacent side surfaces of the regular polygonal prism, and each of the partially adjacent side surfaces is correspondingly provided with a lens module;

[0017] According to the circumferential order with the central axis of the regular polygonal prism as a circle, the projection of the base of the previous lens module along the optical axis direction of the camera unit is at least partially blocked by the base of the next lens module adjacent to the previous lens module.

[0018] In the above technical solution, lens modules are arranged on some adjacent side surfaces of the regular polygonal prism, and in an axial order with the central axis of the regular polygonal prism as a circle, the projection of the base of the previous lens module in the direction of the optical axis of the camera unit blocks the base of the next lens module. The overall structure is compact and can shorten the baseline between the lens modules.

[0019] In some embodiments of the present application, the bracket includes a mounting portion in the form of a polygonal column, and the base of each lens module is mounted on a side surface of the mounting portion.

[0020] In the above technical solution, the mounting part is a polygonal column structure, and the base of each lens module can be conveniently mounted on a side of the mounting part. After the base of each lens module is mounted on a side of a mounting part, the bases of all lens modules naturally form a polygon, so that the optical axes of all camera parts also naturally form a polygonal structure.

[0021] In some embodiments of the present application, the plurality of lens modules include a first lens module, at least one second lens module, and at least one third lens module;

[0022] The at least one second lens module and the at least one third lens module are respectively located on both sides of the optical axis of the base of the first lens module;

[0023] The intersection point of the optical axis of the base of each second lens module and the optical axis of the base of the first lens module is located on a side of the base of the first lens module away from the camera unit;

[0024] The intersection point of the optical axis of the base of each third lens module and the optical axis of the base of the first lens module is located on a side of the base of the first lens module away from the camera unit;

[0025] The projection of the base of the first lens module in the direction along the optical axis of the camera unit is partially blocked by the bases of the second lens module and the third lens module adjacent to the first lens module.

[0026] In the above technical solution, all the second lens modules and all the third lens modules are respectively located on both sides of the optical axis of the base of the first lens module, and the second lens module and the third lens module adjacent to the first lens module are partially blocked by the projection of the base of the first lens module along the optical axis direction of the camera unit. This structure effectively reduces the space occupied by all lens modules while meeting the requirements of wide-range shooting. In addition, this structure can shorten the baseline between lens modules, so that the ghosting between lens modules becomes smaller.

[0027] In some embodiments of the present application, the at least one second lens module includes a plurality of second lens modules, and the base of the second lens module farther away from the first lens module in each of two adjacent second lens modules is located on the inner side of the base of the second lens module closer to the first lens module;

[0028] The at least one third lens module comprises a plurality of third lens modules, and the base of the third lens module farther away from the first lens module in each two adjacent third lens modules is located on the inner side of the base of the third lens module closer to the first lens module.

[0029] In the above technical solution, there are multiple second lens modules, and the base of the second lens module farther away from the first lens module in each adjacent two second lens modules is located on the inner side of the base of the second lens module close to the first lens module. This structure can reduce the space occupied by all lens modules.

[0030] In some embodiments of the present application, the multiple lens modules are distributed on the bracket around a second reference line, the optical axis of each camera part is not in the same plane as the second reference line, and according to the circumferential order of the circle with the second reference line as the axis, the projection of the base of the previous lens module in the direction along the optical axis of the camera part is at least partially blocked by the base of the next lens module adjacent to the previous lens module.

[0031] In the above technical solution, multiple lens modules are distributed on the bracket around the circumference of the second reference line, and the optical axis of each camera unit is not in the same plane as the second reference line, so that the entire shooting device has a larger shooting range; according to the circumferential order of the circle with the second reference line as the axis, the projection of the base of the previous lens module in the direction along the optical axis of the camera unit is at least partially blocked by the base of the next lens module adjacent to the previous lens module, so that the entire shooting device has a compact structure and effectively reduces the space occupied by all lens modules. This structure can shorten the baseline between lens modules and reduce the ghosting between lens modules.

[0032] In some embodiments of the present application, the angles between the optical axes of the respective camera units and the reference plane are equal, and the second reference line is perpendicular to the reference plane.

[0033] In the above technical solution, the angles between the optical axes of each camera unit and the reference plane perpendicular to the second reference line are equal, so that the arrangement of each lens module is more regular and the entire shooting device has a better shooting effect.

[0034] In a second aspect, an embodiment of the present application provides a ball camera, comprising a shell and the above-mentioned shooting device, wherein the shooting device is installed in the shell.

[0035] In the above technical solution, the shooting device has the characteristic of occupying a small space, which makes it easy to install the shooting device in the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Example

[0055] like Figure 1 , Figure 2As shown, an embodiment of the present application provides a shooting device 100, including a bracket 10 and a plurality of lens modules 20 arranged circumferentially, all of the lens modules 20 are mounted on the bracket 10, each of the lens modules 20 includes a base 21 and a camera portion 22 connected to and perpendicular to the base 21, the bases 21 of each two adjacent lens modules 20 are close to or abut against each other, and the projection of the base 21 of each lens module 20 in the direction along the optical axis 221 of the camera portion 22 is at least partially blocked by the base 21 of at least one lens module 20 adjacent to the lens module 20.

[0056] In the above structure, the bases 21 of every two adjacent lens modules 20 are close to or abut against each other, and the projection of the base 21 of each lens module 20 in the direction of the optical axis 221 of the camera unit 22 is at least partially blocked by the base 21 of at least one lens module 20 adjacent to it, that is, each lens module 20 will at least partially overlap with at least one lens module 20 adjacent to it in the space, thereby reducing the space occupied by all lens modules 20, effectively reducing the volume of the entire shooting device 100, and facilitating installation and carrying.

[0057] It should be noted that the above-mentioned multiple lens modules 20 arranged circumferentially are not limited to all lens modules 20 being arranged around the entire circumference.

[0058] Among them, the lens module 20 is a camera, the camera part 22 of the lens module 20 is cylindrical, the base 21 is rectangular plate-shaped, the camera part 22 is connected to one side of the base 21 in the thickness direction, and the camera part 22 is perpendicular to the base 21, that is, the optical axis 221 of the camera part 22 is perpendicular to the base 21. The camera part 22 is an optical lens for taking pictures, and an optical element is arranged inside it, and a circuit board and an image sensor are arranged inside the base 21. The more detailed structure and working principle of the lens module 20 can be referred to the relevant technology, which will not be repeated here.

[0059] The bracket 10 serves to fix each lens module 20 . The bracket 10 may have a variety of structures, and its specific structure depends on the arrangement of the lens modules 20 .

[0060] The lens module 20 in the photographing device 100 can be arranged in various ways. The various arrangements of the lens module 20 are described in detail below with reference to the accompanying drawings.

[0061] In some embodiments of the present application, the optical axes 221 of all the camera units 22 are located in the same plane. This structure can further reduce the space occupied by all the lens modules 20.

[0062] Furthermore, all lens modules 20 are distributed on the bracket 10 around the first reference line 30, and the optical axis 221 of each camera part 22 is perpendicular to the first reference line 30; all bases 21 in all lens modules 20 form a polygon, and the optical axis 221 of each base 21 is located on one side of the polygon, and according to the circumferential order of the circle with the first reference line 30 as the axis, the projection of the base 21 of the previous lens module 20 in the direction along the optical axis 221 of the camera part 22 is at least partially blocked by the base 21 of the next lens module 20 adjacent to the previous lens module 20.

[0063] All lens modules 20 are distributed on the bracket 10 around the first reference line 30, the optical axis 221 of each camera unit 22 is perpendicular to the first reference line 30, and all bases 21 form a polygonal structure with a compact structure. While meeting the requirements of 360-degree panoramic shooting, the space occupied by all lens modules 20 is effectively reduced. In addition, this structure can shorten the baseline between the lens modules 20 (the distance between the lens modules 20 and the lens modules 20), so that the ghosting between the lens modules 20 and the lens modules 20 is reduced.

[0064] The circumferential order of the circle with the first reference line 30 as the axis mentioned above can be a clockwise order or a counterclockwise order. Figure 2 As shown, if the order is in the clockwise direction of the circle with the first reference line 30 as the axis, the projection of the base 21 of the previous lens module 20 in the direction along the optical axis 221 of the camera part 22 (the direction in which the optical axis 221 points from the end of the camera part 22 away from the base 21 to the end of the camera part 22 close to the base 21) is at least partially blocked by the base 21 of the next lens module 20 adjacent to the previous lens module 20; if the order is in the counterclockwise direction of the circle with the first reference line 30 as the axis, the projection of the base 21 of the previous lens module 20 in the direction along the optical axis 221 of the camera part 22 (the direction in which the optical axis 221 points from the end of the camera part 22 close to the base 21 to the end of the camera part 22 away from the base 21) is at least partially blocked by the base 21 of the next lens module 20 adjacent to the previous lens module 20.

[0065] Optionally, the polygon formed by all the bases 21 is a regular polygon, so that the structure of all the lens modules 20 is more compact.

[0066] It should be noted that since the optical axes 221 of the bases 21 of all lens modules 20 are located in the same plane, the camera unit 22 is perpendicular to the base 21, and all bases 21 form a polygonal structure, the optical axes 221 of all bases 21 will also form a polygonal structure.

[0067] In addition, since the projection of the base 21 of the previous lens module 20 in the direction along the optical axis 221 of the camera unit 22 is at least partially blocked by the base 21 of the next lens module 20 adjacent to the previous lens module 20 according to the circumferential order of the circle with the first reference line 30 as the axis, the polygonal structure formed by all the bases 21 is not a polygonal structure formed by connecting all the bases 21 end to end in sequence. Figure 2 Provide detailed explanation.

[0068] like Figure 2 As shown, all bases 21 form a regular pentagonal structure, that is, there are five lens modules 20. For the convenience of description, the bases 21 of the five lens modules 20 are defined as the first base 211, the second base 212, the third base 213, the fourth base 214 and the fifth base 215. The first base 211, the second base 212, the third base 213, the fourth base 214 and the fifth base 215 are distributed in a clockwise direction of a circle with the first reference line 30 as the axis. One end of the second base 212 in a direction perpendicular to the optical axis 221 abuts against or is close to the middle position of the end surface of the first base 211 away from the camera unit 22; the third base 2 One end of the fourth base 214 in the direction perpendicular to the optical axis 221 abuts against or is close to the middle position of the end surface of the third base 213 away from the imaging portion 22; one end of the fifth base 215 in the direction perpendicular to the optical axis 221 abuts against or is close to the middle position of the end surface of the fourth base 214 away from the imaging portion 22; one end of the first base 211 in the direction perpendicular to the optical axis 221 abuts against or is close to the middle position of the end surface of the fifth base 215 away from the imaging portion 22.

[0069] For all the above structures where the bases 21 are arranged in a polygonal shape, the bracket 10 can be of various structures. Figure 3 As shown, the bracket 10 includes a supporting portion 11 and a mounting portion 12 , and the supporting portion 11 is supported at the bottom of the mounting portion 12 .

[0070] The support portion 11 is a circular plate-shaped structure, and a plurality of support legs 111 are provided at the bottom of the support portion 11 . The support legs 111 are perpendicular to the support portion 11 , and the support legs 111 are distributed circumferentially around the axis of the support portion 11 .

[0071] The mounting portion 12 is a polygonal column structure, and in actual installation, the base 21 of each lens module 20 is mounted on a side surface of the mounting portion 12. After the base 21 of each lens module 20 is mounted on a side surface of the mounting portion 12, the optical axis 221 of the camera portion 22 of the lens module 20 will be perpendicular to the side surface, and the bases 21 of all lens modules 20 naturally form a polygon, so that the optical axes 221 of all camera portions 22 also naturally form a polygonal structure.

[0072] Of course, since the bases 21 of all the lens modules 20 form a regular pentagonal structure, the mounting portion 12 is a regular pentagonal prism structure.

[0073] Furthermore, the mounting portion 12 is a hollow structure, the mounting portion 12 is coaxially arranged with the supporting portion 11, and the first reference line 30 is the central axis of the mounting portion 12. A mounting frame 13 for accommodating the base 21 of the lens module 20 is provided on each side surface of the mounting portion 12, and the mounting frame 13 is rectangular. Since the mounting portion 12 is a regular pentagonal prism structure, the mounting portion 12 has five sides, and the number of mounting frames 13 is also five.

[0074] For convenience, the five mounting frames 13 are defined as the first mounting frame 131, the second mounting frame 132, the third mounting frame 133, the fourth mounting frame 134 and the fifth mounting frame 135. The first mounting frame 131, the second mounting frame 132, the third mounting frame 133, the fourth mounting frame 134 and the fifth mounting frame 135 are circumferentially distributed on each side of the mounting portion 12 in sequence with the axis of the mounting portion 12 as the center. One end of the first mounting frame 131 is connected to the middle position of the second mounting frame 132; one end of the second mounting frame 132 is connected to the middle position of the third mounting frame 133; one end of the third mounting frame 133 is connected to the middle position of the fourth mounting frame 134, one end of the fourth mounting frame 134 is connected to the middle position of the fifth mounting frame 135; one end of the fifth mounting frame 135 is connected to the middle position of the first mounting frame 131.

[0075] like Figure 1 As shown, the base 21 of each lens module 20 is accommodated in a mounting frame 13 and abuts against the corresponding side of the mounting portion 12. The base 21 of the lens module 20 is fixed by screws ( Figure 1 The lens modules 20 are fixed to the mounting frame 13 (not shown), so that each lens module 20 is mounted on the bracket 10. After all the lens modules 20 are mounted on the bracket 10, all the bases 21 form the above-mentioned regular pentagonal structure.

[0076] Of course, in other embodiments, after all the lens modules 20 are installed on the bracket 10, all the bases 21 may also form other polygonal structures, for example, all the bases 21 form a triangular structure, a quadrilateral structure, etc. As an example, Figure 4As shown, all the bases 21 form a triangular structure. In this case, the bracket 10 for mounting the lens module 20 can adopt a structure similar to the bracket 10 in which all the bases 21 form a pentagonal structure.

[0077] In the above structure, the regular polygon structure formed by the bases 21 of all lens modules 20 is not a regular polygon structure formed by connecting the bases 21 of all lens modules 20 end to end, and the optical axes 221 of all lens modules 20 do not intersect at one point. However, this regular polygon structure can be transformed from a regular polygon structure in which the optical axes 221 of all lens modules 20 intersect at one point. For example, Figure 5 As shown in the figure, taking five lens modules 20 as an example, the bases 21 of the five lens modules 20 are connected end to end in sequence to form a regular pentagon (of course, there may also be a distance between every two adjacent bases 21), and the optical axes 221 of the five lens modules 20 intersect at the same point. When transforming, one lens module 20 can be used as a reference, and the remaining lens modules 20 can be moved inward in two directions (the direction of the optical axis 221 of the lens module 20, and the direction perpendicular to the optical axis 221 of the lens module 20), and finally the five lens modules 20 can be moved as shown in the figure. Figure 2 The regular pentagonal structure shown. Of course, due to Figure 2 The optical axes 221 of each lens module 20 do not intersect at the same point, and each optical axis 221 can be transformed to a position where it intersects at a point by image mapping transformation.

[0078] In any of the above embodiments, the optical axes 221 of the camera units 22 in all lens modules 20 are located in the same plane, and all lens modules 20 are distributed on the bracket 10 around the first reference line 30, which can be understood as all lens modules 20 are distributed in a columnar shape. In some embodiments of the present application, when the optical axes 221 of the cameras in all lens modules 20 are located in the same plane, all lens modules 20 can also be arranged on the bracket 10 in other distribution modes.

[0079] For example, in some embodiments of the present application, Figure 6 As shown, all the multiple lens modules 20 are distributed on some adjacent side surfaces of the regular polygonal prism, and each of the adjacent side surfaces is provided with a lens module 20. According to the circumferential order with the central axis of the regular polygonal prism as a circle, the projection of the base 21 of the previous lens module 20 along the optical axis direction of the camera unit 22 is at least partially blocked by the base 21 of the next lens module 20 adjacent to the previous lens module 20. The above-mentioned distribution form of the lens modules 20 has a compact overall structure, which can shorten the baseline between the lens modules 20.

[0080] In this embodiment, the bracket 10 may be a regular polygonal prism structure, and the lens modules 20 are correspondingly mounted on some adjacent side surfaces of the bracket 10 .

[0081] In this embodiment, taking a regular polygonal prism as a regular pentagon as an example, the regular polygonal prism has five side faces, wherein the lens module 20 may be disposed on two, three, four, or five adjacent side faces. Figure 6 The lens module 20 is shown to be disposed on three adjacent sides of the regular polygonal prism. Figure 7 As shown, the photographing device 100 includes a first lens module 201, at least one second lens module 202, and at least one third lens module 203. All second lens modules 202 and all third lens modules 203 are respectively located on both sides of the optical axis 221 of the camera portion 22 of the first lens module 201. The intersection of the optical axis 221 of the camera portion 22 of each second lens module 202 and the optical axis 221 of the camera portion 22 of the first lens module 201 is located on the side of the base 21 of the first lens module 201 away from the camera portion 22; the intersection of the optical axis 221 of the camera portion 22 of each third lens module 203 and the optical axis 221 of the camera portion 22 of the first lens module 201 is located on the side of the base 21 of the first lens module 201 away from the camera portion 22. The projection of the base 21 of the first lens module 201 in the direction of the optical axis 221 of the camera unit 22 is partially blocked by the base 21 of the second lens module 202 and the base 21 of the third lens module 203 adjacent to the first lens module 201 .

[0082] The distribution structure of the lens modules 20 mentioned above effectively reduces the space occupied by all lens modules 20 while meeting the requirements of wide-range shooting. At the same time, this distribution structure can shorten the baseline between the lens modules 20, thereby reducing the ghosting between the lens modules 20.

[0083] Furthermore, all the second lens modules 202 and all the third lens modules 203 are symmetrically distributed on both sides of the optical axis 221 of the camera portion 22 of the first lens module 201 .

[0084] In this embodiment, continue to refer to Figure 7 , there are multiple second lens modules 202 and multiple third lens modules 203. The base 21 of the second lens module 202 far from the first lens module 201 in each of two adjacent second lens modules 202 is located inside the base 21 of the second lens module 202 close to the first lens module 201; the base 21 of the third lens module 203 far from the first lens module 201 in each of two adjacent third lens modules 203 is located inside the base 21 of the third lens module 203 close to the first lens module 201. The above structure can effectively reduce the space occupied by all lens modules 20.

[0085] The inner side of the base 21 of the second lens module 202 referred to above is the side of the base 21 of the second lens module 202 facing the optical axis 221 of the first lens module 201, and is also the side of the base 21 of the second lens module 202 away from the camera unit 22. Similarly, the inner side of the base 21 of the third lens module 203 is the side of the base 21 of the third lens module 203 facing the optical axis 221 of the first lens module 201, and is also the side of the base 21 of the third lens module 203 away from the camera unit 22.

[0086] It should be noted that, in addition to the case where both the second lens module 202 and the third lens module 203 are multiple, the number of the first lens module 201 and the third lens module 203 can also be other cases. For example, in other embodiments, the first lens module 201 is one and the third lens module 203 is multiple; or the first lens module 201 is multiple and the third lens module 203 is one; or the first lens module 201 and the third lens module 203 are both one. As an example, Figure 8 As shown, the second lens module 202 and the third lens module 203 are both one.

[0087] The above lens module arrangement structure can be obtained by translation transformation of the lens module arrangement structure in which each lens module 20 is located on the same circumference and the optical axes 221 of each lens module 20 intersect at one point, that is, taking one lens module 20 in the lens module 20 arrangement structure in which each lens module is located on the same circumference and the optical axes 221 of each lens module 20 intersect at the center of the circle as a reference, the remaining lens modules 20 are all moved inward along two directions (the direction of the optical axis 221 of the lens module 20 and the direction perpendicular to the optical axis 221 of the lens module 20). Of course, each optical axis 221 can also be transformed to a position intersecting at the center of the circle by image mapping transformation.

[0088] In any of the above embodiments, the optical axes 221 of the camera parts 22 in all lens modules 20 are located in the same plane. In some embodiments of the present application, the optical axes 221 of the camera parts 22 in all lens modules 20 may not be located in the same plane.

[0089] like Fig. 9 , Fig.10 As shown, all lens modules 20 are distributed on the bracket 10 around the second reference line 40, and the optical axis 221 of each camera part 22 is not in the same plane as the second reference line 40. According to the circumferential order of the circle with the second reference line 40 as the axis, the projection of the base 21 of the previous lens module 20 in the direction along the optical axis 221 of the camera part 22 is at least partially blocked by the base 21 of the next lens module 20 adjacent to the previous lens module 20.

[0090] In the above structure, multiple lens modules 20 are distributed on the bracket 10 around the second reference line 40, and the optical axis 221 of each camera unit 22 is not in the same plane as the second reference line 40, so that the entire shooting device 100 has a larger shooting range; according to the circumferential order of the circle with the second reference line 40 as the axis, the projection of the base 21 of the previous lens module 20 in the direction along the optical axis 221 of the camera unit 22 is at least partially blocked by the base 21 of the next lens module 20 adjacent to the previous lens module 20, so that the entire shooting device 100 has a compact structure and effectively reduces the space occupied by all lens modules 20. This structure can shorten the baseline between the lens modules 20, so that the ghosting between the lens modules 20 and the lens modules 20 is reduced.

[0091] The optical axes 221 of the camera units 22 of any two lens modules 20 among all the lens modules 20 are also not in the same plane.

[0092] It should be noted that the circumferential order of the circle with the second reference line 40 as the axis mentioned above can be a clockwise order or a counterclockwise order. Fig.10 As shown, if the order is in the clockwise direction of the circle with the second reference line 40 as the axis, the projection of the base 21 of the previous lens module 20 in the direction along the optical axis 221 of the camera part 22 (the direction in which the optical axis 221 points from the end of the camera part 22 away from the base 21 to the end of the camera part 22 close to the base 21) is at least partially blocked by the base 21 of the next lens module 20 adjacent to the previous lens module 20; if the order is in the counterclockwise direction of the circle with the second reference line 40 as the axis, the projection of the base 21 of the previous lens module 20 in the direction along the optical axis 221 of the camera part 22 (the direction in which the optical axis 221 points from the end of the camera part 22 close to the base 21 to the end of the camera part 22 away from the base 21) is at least partially blocked by the base 21 of the next lens module 20 adjacent to the previous lens module 20.

[0093] Further, continue to refer to Fig.10 , the angles between the optical axes 221 of each camera unit 22 and the reference plane 50 are equal, and the second reference line 40 is perpendicular to the reference plane 50. This structure makes the arrangement of each lens module 20 more regular, so that the entire shooting device 100 has a better shooting effect.

[0094] It is understandable that the bracket 10 can have a variety of structures as long as the bracket 10 can fix each lens module 20 .

[0095] In this embodiment, Fig.11As shown, the bracket 10 includes a support portion 11, a support column 14 and a plurality of mounting frames 13. The two axial ends of the support column 14 have opposite bottom ends and top ends. The bottom end of the support column 14 is connected to the support portion 11. All mounting frames 13 are distributed on the support portion 11 with the support column 14 as the center. Each mounting frame 13 is arranged obliquely on the support portion 11, and all mounting frames 13 meet at the top end of the support column 14. The support column 14 of this structure has good structural stability and firmness.

[0096] The support portion 11 is a circular plate-shaped structure, and the support column 14 is coaxially arranged with the support portion 11. The number of the mounting frames 13 is consistent with the number of the lens modules 20. In this embodiment, there are five mounting frames 13 and five lens modules 20. In other specific embodiments, the number of the mounting frames 13 and the lens modules 20 can also be other numbers, such as three, four, etc.

[0097] During installation, the base 21 of each lens module 20 is accommodated in a mounting frame 13 , and the base 21 of the lens module 20 is fixed to the mounting frame 13 by screws, so that each lens module 20 is installed on the bracket 10 .

[0098] The above lens module arrangement structure can be obtained by translation transformation of the lens module arrangement structure in which each lens module is located on the same sphere and the optical axis 221 of each lens module 20 intersects at the center of the sphere, that is, taking one lens module 20 in the lens module 20 arrangement structure in which each lens module is located on the same sphere and the optical axis 221 of each lens module 20 intersects at the center of the sphere as a reference, the remaining lens modules 20 can be moved in two directions (the direction of the optical axis 221 of the lens module 20 and the direction perpendicular to the optical axis 221 of the lens module 20). Of course, each optical axis 221 can also be transformed to a position intersecting at the center of the sphere by image mapping transformation.

[0099] In addition, an embodiment of the present application further provides a ball camera, comprising a housing and the shooting device 100 in any of the above embodiments, wherein the shooting device 100 is installed in the housing.

[0100] Since the photographing device 100 occupies a small space, the photographing device 100 can be conveniently installed in a housing.

[0101] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
