Description

[0039] In this embodiment, the laser radar 2 is a mechanical laser radar. The multiple cameras 3 are all monocular cameras. The number of cameras 3 is determined by the field of view of the camera 3 and the desired field of view of the roadside. As a preferred embodiment, the number of cameras 3 is 4, and the field of view of the 4 cameras 3 covers 360°. There are 8 evenly distributed mounting holes on the inner side of the awning 1 for fixing the cameras 3.
