Parking space ground lock system and parking space sharing method

The invention provides a parking space ground lock system and a parking space sharing method. The parking space ground lock system comprises an identification pile, a ground lock, a business server and an algorithm optimization server, the identification pile comprises a mainboard, a camera, a radar, a stretching device and a communication module; the main board is connected with the camera, the radar, the stretching device and the communication module. The stretching device controls rising and falling of the parking lock through pulling back and releasing of a steel cable. The camera and the radar are used for acquiring images and radar reflection signals and transmitting the images and the radar reflection signals to the mainboard, a CPU and a storage chip are arranged on the mainboard and used for operating a convolutional neural network to process the images and radar information, and the mainboard is further used for controlling the stretching device to be pulled back and released so as to control rising
