[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0030] Please refer to Figs. 1-4 The three-view camera assembly can include the following contents.

[0031] The front cover 1, the rear cover 2 and the cover plate 3 are assembled by buckling;

[0032] The first camera 11, the second camera 12 and the third camera 13 are assembled on the inner side of the front cover 1;

[0033] The first camera 11 and the second camera 12 are arranged out of the cover plate 3;

[0034] The third camera 13 is arranged out of the rear cover 2;

[0035] The cover plate 3 is assembled with the lighting unit 31.

[0036] Here, the front cover is uniformly assembled with three-view cameras, wherein the first camera and the second camera are arranged out of the holes on the cover plate, and the third camera is arranged out of the hole on the rear cover, so as to realize the limiting positioning.

[0037] In addition, the lighting unit is also assembled at the cover plate, so as to illuminate the shooting area of the first camera and the second camera, and ensure the shooting quality.

[0038] In the embodiment, the first camera 11, the second camera 12 and the third camera 13 are rotationally assembled relative to the front cover 1.

[0039] Here, within the limiting range of the holes on the cover plate and the rear cover, the first camera, the second camera and the third camera can be rotated in a small range, so that the orientation of each camera can be fine-tuned according to the specific situation of the installation area, and the shooting view angle can be optimized.

[0040] In this embodiment, the first camera 11, the second camera 12 and the third camera 13 are provided with electronic zoom function.
