AI-based intelligent parking lot parking guidance method and artificial intelligence server

The invention provides an AI-based intelligent parking lot parking guidance method and an artificial intelligence server. The parking lot traffic flow trajectory set of different parking indication time nodes of a to-be-guided vehicle is analyzed, and the real-time positions and driving trajectories of other vehicles in an intelligent parking lot are considered, and therefore, a vehicle parking guidance instruction corresponding to the to-be-guided vehicle is determined and generated timely and accurately, so that a vehicle-mounted controller realizes parking guidance or automatic driving of the to-be-guided vehicle based on the vehicle parking guidance instruction. Through real-time iteration of the vehicle parking guidance instruction, the real-time traffic flow condition of the intelligent parking lot can be considered, so that coping adjustment of potential scratch accidents or other vehicle emergencies is realized based on the artificial intelligence server, and the safety and orderliness when the to-be-guided vehicle is guided to park can be ensured. Thus, the intelligent parking lot can be effectively managed in real time, and congestion caused by vehicle scratching in the parking process is avoided.
