Abstract

The invention relates to a car searching method and system by combining supersonic waves with a video technology. Each supersonic parking stall detector detects vacancy state information of a parking stall, when the vacancy state of the parking stall is changed, the supersonic parking stall detector sends a license plate snapshot identification signal to a video parking stall detector in a wireless communication manner, the video parking stall detector carries out snapshot, the license plate number of a car is identified, and data information is transmitted to a background management server in a unified way to implement unified management. The supersonic parking stall detectors are combined with the video parking stall detector to improve the car searching efficiency and accuracy, and the work burden of the video parking stall detector is reduced.

Description

technical field [0001] The invention relates to the technical fields of wireless communication and electronic equipment, and in particular to a method and system for finding cars by combining ultrasonic waves with video technology. Background technique [0002] With the advancement of science and technology and economic development, urban vehicles are also increasing rapidly, which leads to problems such as difficulty in parking and finding a car. Although a large parking lot can meet the parking needs of car owners, how to quickly and accurately find a parking space is still an urgent problem for car owners. [0003] The car-finding system in the parking lot in the prior art usually recognizes the idle state of the parking space through a pure video parking space detector, such as Figure 4 As shown, the recognition accuracy of the parking space status information is completely dependent on the image recognition results of the video detector. The image detection of the vide...
