Title:
UNDERGROUND PARKING LOT PASSAGE MOVING VEHICLE REAL-TIME DETECTION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/044870
Kind Code:
A1
Abstract:
Disclosed are an underground parking lot passage moving vehicle real-time detection system and method. The detection system comprises a millimeter-wave radar used to generate electromagnetic waves, a metal marking strip installed on a center line of a parking lot passage, a data analysis unit used to analyze reflected waves which are reflected back, a data storage unit, a communication unit used for data transmission, and a host computer. The steps of the detection method are: generating and emitting electromagnetic waves on the basis of the millimeter-wave radar; reflecting the electromagnetic waves, to acquire reflected waves; detecting a coordinate position, a direction of motion and a motion trajectory of a moving vehicle in the parking lot passage on the basis of the reflected waves. In the present invention, a detection area is accurate and controllable, and the target coordinate position, speed, direction of motion and motion trajectory information of a vehicle can be detected; the technology is mature, and the cost is low.
