Object detection method based on overlooking depth camera

The invention relates to an object detection method based on an overlooking depth camera. According to the method, all objects in the area to be detected can be detected by using the RGB-D camera, andthe information of the detected objects can be sent to an unmanned vehicle, so that the unmanned vehicle can continuously plan a path according to the received information, and unmanned driving is realized. The cost of the RGB-D camera adopted by the invention is much lower than that of a laser radar, so that the cost for realizing an unmanned driving technology can be effectively reduced. Meanwhile, an anti-reflection license plate is adopted, the license plate is arranged at the top of the vehicle, symbols on the license plate are concave inwards, the reflection effect is greatly reduced, and great contrast between the symbols and other areas can be formed under the condition that sunlight is strong in the daytime, so that the license plate can be effectively identified by using image vision technologies such a
