In the present embodiment, the material of the sensor mounting frame 110 may be ordinary thin steel plate, usually made by welding a base plate and a stiffener (commonly known as reinforcing rib) together. A mounting position for the sensor may be reserved on the sensor mounting frame 110.

Therefore, the sensor mounting frame 110 may be made of any material having these characteristics.

In addition, the surround-view camera may also identify the parking lane marking, curb and nearby vehicles. The front-view camera may be mounted at the end of the sensor mounting frame 110 proximate to the front of a driverless vehicle to monitor an obstacle in front of the vehicle.
