The mounting frame is mounted with a first lens 51 and a second lens 52; the mounting frame is provided with a first circuit board assembly, a second circuit board assembly, a first reflecting mirror 81 and a second reflecting mirror 82, the first reflecting mirror 81 for guiding the first light beam 91 of the first lens 51 to be transmitted to the first circuit board assembly, and the second reflecting mirror 82 for guiding the second light beam 92 of the second lens 52 to be transmitted to the second circuit board assembly. The mounting frame is provided with the first lens 51 and the second lens 52, and the first lens 51 and the second lens 52 collect light beams in different directions respectively, so that the application range of the camera assembly is expanded. The multi-light-path design is realized through the first lens 51 and the second lens 52, the visual field range can be increased, the camera assembly has the effects of low optical distortion and high resolution, the visual field effects of fish eyes and a large wide angle can be achieved, the function of various visual fields can be met by one camera assembly, and the requirements of simultaneously covering the corresponding visual fields and meeting various performances of image quality can be met.
