Recognizable mark-based parking position detecting method

Abstract

The invention discloses a recognizable mark-based parking position detecting method. The method comprises the following steps: (1) setting a recognizable mark uniquely representing the parking position in each parking region, wherein the recognizable mark is characters or patterns, when the parking position is occupied, the mark can be completely covered by a vehicle rather than being acquired; (2) acquiring a image in the parking position region, and converting the image into a digital image; (3) searching and identifying the recognizable mark; (4) considering the parking position is in spare sate when the recognizable mark in the corresponding parking position is detected from the digital image, otherwise considering the parking position is occupied; and (5) outputting the parking position information of the spare parking position. By using the recognizable mark-based parking position detecting method, automatic acquisition, panoramic scanning, automatic focusing, spare parking position automatic positioning acquisition and other complicated functions on the image in the whole or partial region of the parking lot can be realized, and the method has excellent technical effect relative to the conventional detecting method.

Description

technical field [0001] The invention relates to a method for detecting a parking space based on an identifiable mark, more specifically, to a method for detecting a parking space in a parking lot information management system or a parking guidance system. Background technique [0002] At present, with the improvement of people's living standards, the number of cars is increasing. At the same time, due to population and urban growth, there are fewer and fewer places to park. "It is easy to buy a car and difficult to park". Not only the number of parking spaces is far from meeting the parking needs of the owners, but also, even inside the parking lot, since the parking spaces are constantly changing, it is difficult to find and search for parking spaces manually. Very time wasting. [0003] Therefore, in order to better discover and grasp the real-time conditions of the parking lot, in the parking lot information management system or parking guidance system, people have adop...

Problems solved by technology

[0007] However, the application of these two parking space detection systems has its limitations or shortcomings. The former must install instruments above the parking space, and an ultrasonic device can only monitor one parking space, and is generally only used in underground parking lots; The road surface must be damaged during installation, which will cause relatively large losses, and it is not conducive to upgrading or maintenance once the installation is completed. Therefore, these two technical solutions have their own shortcomings
