Embodiment Construction
[0046] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0047] A method for detecting an empty parking space. First, a small number of cameras are used to capture images of the parking lot. Considering that most of the existing parking spaces are outlined with brighter colors (for example, white), the image is segmented using the threshold method. Find multiple connected regions by segmenting the results. In the present invention, each parking space can be regarded as a connected area. Firs...

The invention discloses a detection method and a detection system for a vacant parking space. The detection method comprises the following realization process: firstly, obtaining a parking lot image by using a camera; then processing the whole image and segmenting all parking spaces into corresponding communicating areas; from the beginning of the parking space in the first communicating area, judging whether the parking space is a vacant parking space or not and calculating included area information of the parking space; calculating adjacent communicating areas of the first communicating areato obtain the included area information of the adjacent communicating areas; judging whether the parking space is the vacant parking space or not by taking a difference value between the first communicating area and the adjacent communicating areas; iteratively judging all the connecting areas and outputting judging results. Compared with the prior art, the detection method and the detection system for the vacant parking space, disclosed by the invention, have the advantages of being simple, easy to implement, broad in application prospect, high in practicability and wide in application range; the vacant parking space can be found out accurately in real time, so that the problem of difficulty in parking in public places can be effectively alleviated.
Description
technical field [0001] The invention relates to the technical field of parking space detection, in particular to an empty parking space detection method and system. Background technique [0002] With the continuous development of science and technology economy, people's living standards continue to improve, and the number of motor vehicles is also increasing year by year, resulting in serious parking problems, the most serious problem is the difficulty of parking, therefore, smart parking is the future of parking development trend. Most of the existing smart parking lots are underground parking lots, which are realized by installing a large number of geomagnetic induction devices. However, it is relatively high to install a large number of ground stimulation devices, and it is not easy to realize for the above-ground parking lot. [0003] Therefore, how to complete the detection of empty parking spaces in the above-ground parking lot at a lower cost is of great significanc...
