Method and system for detecting parking space states of parking lot

Abstract

The invention provides a method and a system for detecting the parking space states of a parking lot. The detection method comprises the following steps of acquiring a first grayscale image of a parking lot in a non-vehicle state; converting the first grayscale image into a contour image; acquiring the regional information of each parking space according to the contour image, wherein the regionalinformation comprises the regional range and the position information of each parking space; acquiring a second grayscale image of the parking lot in the current state; performing contour detection oneach parking space in the second grayscale image according to the regional information, obtaining the sum of the contour area corresponding to each of all parking spaces through calculation, whereinthe sum of the contour area is the sum of the areas of all contours in the region of a certain parking space in the second grayscale image; respectively comparing the sum of all contours with a presetjudgment threshold value to obtain the idle state of each parking space in the parking lot in the current state. According to the invention, an idle parking space can be accurately fed back to the owner of a vehicle. Therefore, the owner can conveniently find the idle parking space, and the parking time is saved. The detection accuracy and the detection timeliness are improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to a parking guidance technology, in particular to a method and system for detecting the state of a parking space in a parking lot. Background technique [0002] my country is one of the countries with a large population in the world. With the rapid economic development, people's living standards have been greatly improved. They are no longer satisfied with basic food and clothing, and then strive to pursue the quality of life. Nowadays, private cars have almost become the standard equipment of every family, which not only represents the quality of life, but also greatly facilitates people's travel. But while private cars are rapidly popularizing, as a populous country, the ensuing vehicle congestion problem is really a headache. Especially when it comes to work, get off work, and holidays, "difficulty in traveling" has become a common problem in various cities. It is even ...

Problems solved by technology

[0006] In the process of detecting the state of the parking space, it is found that according to the different shooting angles in the actual situation, or the problem that the parking space line is blocked after the parking space is occupied, it will bring great inconvenience to the actual detection of the state of the parking space. The actual detection There will be some deviation in the results
