When the number of the camera modules 30 is two, the axial center distance between the lens optical axes of the two camera modules 30 can be set according to the shooting requirements of different occasions, for example, when the multi-camera is applied to an automatic driving vehicle, the proper axial center distance can be set to enable the multi-camera to meet the 3D display shooting requirements, so that the distance, the size and other information of the object in front of the road can be obtained according to the images acquired by the multi-camera.
In the embodiment of the invention, at least two camera modules 30 of the multi-camera share the same circuit board 20, so that the circuit board 20 can synchronously transmit the image acquisition instructions to each camera module 30, thereby enabling each camera module 30 of the multi-camera to synchronously acquire the image data.
In the embodiment of the present invention, the specific structure of the housing 10 is not limited, and in order to improve the installation convenience of the multi-camera, as shown in fig. 1, in one embodiment of the present invention, the housing 10 includes a main housing 11 and a rear housing 12, and the main housing 11 and the rear housing 12 are fixedly connected to form a receiving space for receiving the circuit board 20 and at least two camera modules 30. The main housing 11 and the rear housing 12 may be connected by a fastener, or may be fixedly connected by fastening, bonding, or the like, which is not strictly limited in the present application.
Referring to fig. 1, the multi-view camera further includes a first sealing gasket 40 located at a connection portion between the main housing 11 and the rear housing 12, when the main housing 11 is fixedly connected with the rear housing 12, the first sealing gasket 40 can be elastically deformed to realize sealing under the extrusion action of the main housing 11 and the rear housing 12, so as to prevent external impurities from entering the housing 10, especially when the multi-view camera is applied to an outdoor environment, the first sealing gasket 40 can effectively prevent external water vapor, floating dust, impurities and the like from entering the housing 10, and avoid adverse effects on performance of the multi-view camera.
The specific implementation manner of installing the camera modules 30 in the housing 10 is not limited, as shown in fig. 1, in the embodiment of the present invention, a surface of one side of the main housing 11 away from the rear housing 12 is provided with installation holes 13 corresponding to each camera module 30 one by one, the camera modules 30 are installed in the corresponding installation holes 13, and the lens of the camera module 30 is disposed towards one side facing away from the rear housing 12.
