Parking space geographic information collection and parking space detection method based on roadside packing lot

Abstract

The invention relates to a parking space geographic information collection and parking space detection method based on a roadside packing lot. The parking space geographic information collection and parking space detection method is characterized by including the following steps that the parking space geographic information collection function is achieved through parking space number records which are generated in a background server and bound with space physical locations; parking space detection is conducted through the parking space records bound with the space physical locations and through parking space detectors which are installed near sidelines on the two sides of each parking space. By collecting the longitude and latitude coordinate values of the center point of each parking space and generating the parking space number records bound with the longitude and latitude coordinate values of the center point of each parking space in the background server, parking space detection is conducted through the public detectors which are adjacent in space physical locations with an intersection effect method, for the non-public detectors which are not adjacent in space physical locations, respectively independent dual detectors are adopted for detection and judgment, and therefore limitation and one-sidedness of parking space detection through the two parking space detectors on the sidelines beside one parking space are overcome, and detection accuracy is improved.

Description

Technical field [0001] The invention belongs to the technical field of parking lot monitoring, in particular to a parking space geographic information collection and parking space detection method based on a roadside parking lot. Background technique [0002] With the rapid growth of the number of cars in China, roadside parking lots continue to improve vehicle emission methods to increase the storage density of vehicles per unit space: the original method of vehicles on both sides of the road has been improved to vehicles on both sides of the road. When the vehicles are arranged in a left-to-right way, because the distance between the center points of the two parking spaces (arranged along the width of the vehicle) is shortened, if you continue to use the traditional parking space detector The method is installed at the center point of each parking space. When there is a car in the adjacent parking space, the magnetic field coverage area of ​​the car will cover the detector on t...

Problems solved by technology

But this method is only applicable to an ideal situation: the physical positions of all parking spaces are continuous. In this case, two parking spaces with continuous physical positions will generate common borders and common detectors. When two When there are cars in two parking spaces at the same time, the public detectors on the public sideline will produce an intersection effect (magnetic field superposition), and judge whether there is a car in the adjacent parking space through the intersection effect
