the support base 100 comprises a main support base 110, and a plurality of mounting holes are formed in the main support base 110 and are used for correspondingly inserting the image acquisition pieces one by one so as to fix the image acquisition pieces.

The structure of the mounting holes may be different depending on the specific structure of the image capturing member 200, and it is sufficient to be able to define the position and angle of the image capturing member 200. The mounting hole penetrates through two opposite side surfaces of the supporting seat 110, and the hole axis of the mounting hole refers to a straight line passing through the center of the first side opening and the center of the second side opening of the mounting hole at the same time. If the image acquisition member 200 is a camera, after the camera is inserted into the mounting hole, through the mutual butt limiting effect of the inner wall of the mounting hole and the outer wall of the camera, the optical axis of the camera is parallel or coincident with the hole axis of the mounting hole, and then the angle of the camera is determined through the structure and the angle of the mounting hole. The angle and the position of the mounting hole are determined, the shooting range and the shooting position of the camera are determined, the internal parameters and the external parameters of the camera are designed and selected according to the requirements of shooting scenes, the angle of the main supporting seat 110 is designed and determined in the field of view range of the camera, the field angle of the camera and the angle of the optical axis of each camera are determined, the mounting hole is processed according to the angle of the optical axis of the camera, images acquired by different cameras can be easily integrated when the camera is mounted in the mounting hole, such as splicing, mutual assistance, local amplification and the like, and after the camera and the supporting seat 100 subjected to precision machining are assembled together, assembly errors are involved, and the errors can be achieved by carrying out one-time integral calibration on the basis that the camera is assembled to the supporting seat 100 into a whole, namely, one-time unified calibration processing is carried out before the terminal scene is used. During field installation, the calibrated whole is directly installed, and because the calibration is performed in advance, the field image acquisition can be directly performed without the field calibration, and the acquired images can be integrated. The method does not need to recalibrate a single camera when being used in combination on site, and realizes the feasibility of combining a plurality of cameras on site.

The camera head can be generally divided into a lens including a barrel and at least one lens accommodated in the barrel, and the optical axis of the image pickup 200 refers to the optical axis of the lens. The substrate includes a support plate, an image sensor, a PCB, etc. connected to each other. The extension of the substrate is generally larger than that of the lens, or the substrate protrudes from the lens on the side wall of the lens. The mounting hole may determine the angle of the image capturing member 200 by abutting one of the base plate and the lens. If the camera is limited in a step form matched with the outer contour of the camera. More specifically, the mounting hole includes a through hole area and a slot area, which are communicated, and the through hole area and the slot area respectively penetrate through two opposite sides of the main support seat 110, or the through hole area penetrates through the front surface of the main support seat 110, and the slot area is formed on the back surface of the main support seat 110, and the outer contour of the slot area is adapted to the contour of the substrate of the image capturing element 200, so as to be sleeved with the substrate of the image capturing element 200. When the substrate is mounted in the groove-shaped region, the side wall of the groove-shaped region is abutted against the edge of the substrate, and the bottom wall of the groove-shaped region is connected with the surface of the substrate, so that the angle and the position of the image acquisition member 200 are fixed. The through-hole area is for passing through the lens of the image pickup member 200. The inner wall of the through hole area can be matched with the outer contour of the lens, the lens can be abutted with the inner wall of the through hole area, or the lens can be arranged at intervals with the inner wall of the through hole area. The substrate and the trough-shaped region may be joined using an adhesive.

In the prior art, a plurality of small-angle camera devices are used, but image information acquired by a single camera device can only be checked singly, information integration of a plurality of camera devices cannot be carried out, such as image splicing of different cameras, and the like, if information integration is needed, on-site calibration of each camera device is needed on an installation site, the calibration process is professional and complicated, the implementation is dependent on special technicians, and on-site calibration of a plurality of independent camera devices cannot be realized in practice due to factors such as budget, on-site environment and the like, and information integration of a plurality of camera devices cannot be completed. Compared with the prior art, in the file, at least two image acquisition pieces are fixed on the supporting seat, and the whole image acquisition pieces are calibrated in advance before delivery or field installation, so that the image acquisition pieces meet the image integration requirement, and when the image acquisition pieces are installed in the field, the acquisition of image information in a scene and the integration of the image information acquired by different image acquisition pieces can be directly realized after the whole installation, such as splicing, identification amplification and the like, the field temporary calibration of a single image acquisition piece is not needed, and the problems of difficulty in realizing the field calibration of each image acquisition piece independently, high cost and low efficiency in the prior art are solved.

The supporting seat can be sold independently, and can be used by inserting the image acquisition member 200 with a specified model or the camera into the mounting hole for assembly, or the supporting seat can be assembled with the image acquisition member 200 to be sold as a camera module. For convenience of description, the following embodiments of the present application are described with respect to a camera module including a support base, and it is understood that embodiments of the support base related to the camera module may be embodiments of a separate support base.

The camera module provided by the embodiment of the application comprises the supporting seat 100 according to any one of the above. And at least two image capturing members 200, at least two image capturing members 100 are inserted in one-to-one correspondence with the mounting holes.

The plurality of mounting holes includes at least two first mounting holes 121. The image capturing element 200 includes a first camera 210, where the first camera 210 is inserted into the first mounting hole 121 of the supporting seat 100. The projections of the hole axes of the adjacent first mounting holes 121 on the same horizontal plane form a preset horizontal included angle, so that the projections of the optical axes of the adjacent first cameras 210 positioned in the first mounting holes 121 on the same horizontal plane form a preset horizontal included angle.

So that the first camera 210 shoots different areas at different angles, respectively, and by image processing and stitching, the stitching of the images with small angles into the images with large angles can be realized. The first camera 210 may use a camera with a small angle of view, or a camera with an angle of view smaller than the range of the scene, to ensure high resolution. By matching the plurality of first cameras 210, the effect of enlarging the angle of view range and simultaneously ensuring the resolution of the image is achieved. The preset horizontal included angle is greater than or equal to 0 degree and less than or equal to 90 degrees, so that the resolution is reduced due to the fact that the angle is not too large, the image quality is affected, and therefore splicing is affected.

In one embodiment, all of the first mounting holes 121 may be located at the same height, and the first cameras 210 may photograph in a direction of the optical axis level, that is, the hole axes of at least two of the first mounting holes 121 are located in the same horizontal plane. The projection of the hole axes of the first mounting holes 121 on the same horizontal plane coincides with the hole axes of the first mounting holes 121, i.e. the hole axes of at least two first mounting holes 121 are located in the same plane. So that at least two first cameras 210 are at the same height and both acquire images in the horizontal direction, and then ensure that the images acquired by different first cameras are at the same horizontal plane, thereby making the effect of splicing the images better.

In some other embodiments, the first camera 210 photographs in a direction with the optical axis inclined downward, that is, the hole axis of the first mounting hole 121 forms a preset vertical angle with the horizontal plane, for the case where the mounting position of the camera module is higher. The size of the preset vertical included angle can be set according to the actual required installation position of the camera module and a scene to be photographed, such as 30 degrees, 45 degrees and the like. In the embodiment in which the first camera 210 shoots obliquely downward, all the first mounting holes 121 may be located at the same height, or may be located at different heights, for example, the number of the first mounting holes 121 is three, the height of the middle first mounting hole 121 is slightly higher than the height of the first mounting holes 121 on both sides, and the first mounting holes 121 on both sides are located at the same height.

In one embodiment, among the at least two first mounting holes 121, two first mounting holes 121 located at the outermost side are symmetrically disposed. If the number of the first mounting holes 121 is two, the two first mounting holes 121 are arranged in the horizontal direction, the two first mounting holes 121 are symmetrically distributed in the horizontal direction, or if the number of the first mounting holes 121 is three, the three first mounting holes 121 are arranged in the horizontal direction, and the two first mounting holes 121 located at the outer side are symmetrically distributed in the horizontal direction. In some more specific embodiments, the main support block 110 includes a front face 111, the front face 111 being intended to face the user and the use scene, being the outermost visible surface of the support block. Among the at least two first mounting holes 121, the included angle and the vertical distance between the two first mounting holes 121 located at the outermost side and the front end face 111 are consistent, so that the two first cameras 210 located at the outermost side can acquire images at the same distance and angle as a scene or a person to be photographed, and the images can be spliced conveniently.

In one embodiment, the plurality of mounting holes further includes a second mounting hole 122 for panoramic acquisition and extraction of information such as speaker location. The image capturing element 200 includes a second camera 220, and the second camera 220 is inserted into the second mounting hole 122 of the supporting seat 100.

The second camera 220 has a larger angle of view than the first camera 210, and the first camera 210 has a higher resolution than the second camera 220, and the second camera 220 is intended to be able to pan over a larger area to obtain global image information.

It should be noted that, the first camera 210 obtains local image information of different areas, the second camera 220 obtains panoramic information, the panoramic information can be used for positioning, and the local image information can be used for amplifying and writing an image of a specific location, which can be called as integration of the image information. The basis for the integration of the image information is that the support base 100 fixes the position of the image acquisition member 200, and the support base 100 enables the image acquisition member 200 to comply with the calibration parameter setting, so that the image acquisition member 200 is not required to be calibrated on site separately.

It can be understood that the first mounting hole 121 and the second mounting hole 122 are mounting holes formed in the supporting seat 100, and the structures of the first mounting hole 121 and the second mounting hole 122 may be the same or different, and the first mounting hole 121 and the second mounting hole 122 are respectively used for mounting cameras with different angles of view. The first camera 210 and the second camera 220 are both image acquisition pieces 200, the angles of view of the first camera 210 and the second camera 220 are different, the angle of view of the first camera 210 is smaller, the definition is high, the second camera 220 is a large angle of view camera, the first camera 210 is correspondingly installed in the first installation hole 121, and the second camera 220 is correspondingly installed in the second installation hole 122.

In the embodiment where the hole axis of the first mounting hole 121 forms a preset vertical angle with the horizontal plane, the angle between the hole axis of the second mounting hole 122 and the horizontal plane may be the same as the preset vertical angle, so that the second camera 220 and the first camera 210 have the same pitch angle, or the angle between the hole axis of the second mounting hole 122 and the horizontal plane may be different from the preset vertical angle, and may be set according to practical requirements.
