Embodiment Construction
[0046] In order to enable those skilled in the art to further understand the structure, characteristics and other purposes of the present invention, now in conjunction with the attached preferred embodiments in detail as follows, the described preferred embodiments are only used to illustrate the technical solutions of the present invention, not limit the invention.
[0047] figure 1 A flow chart of the video-based high-position roadside parking detection method according to the present invention is given. Such as figure 1 Shown, according to the high position roadside parking detection method based on video of the present invention comprises:
[0048] The first step S1 is to obtain a video image through a camera installed at a high position, and draw a quadrilateral area as a parking space area according to the parking space line in the video image;
[0049] The second step S2 is to collect the current frame video image, perform license plate recognition, and obtain the po...

The invention provides a video-based high-position roadside parking detection method, which comprises the steps of acquiring a video image through a high-position camera, and marking out a parking space area; obtaining a license plate area and a character recognition result; obtaining a matching area of the license plate; obtaining a search area of the matching area; if the license plate is identified in the parking space area of the previous frame and the same license plate is not identified in the parking space area of the next frame, or the parking space area of the previous frame has a matching area and the license plate is not recognized in the current frame of parking space area, searching a candidate matching area with the maximum matching value with the matching area in the searcharea, updating the matching area as the candidate matching area when the maximum matching value is not smaller than the matching threshold value, and otherwise, updating the state of the parking spacearea as null; and detecting the parking space state of the parking space area in the current frame of video image. Compared with the prior art, the method can quickly and effectively detect the stateof the roadside parking space.
Description
technical field [0001] The invention relates to image processing, video monitoring and security protection, in particular to a roadside parking detection method and device. Background technique [0002] With the rapid increase in the number of motor vehicles in recent years, the number of supporting parking lots has grown slowly. When there is not enough space to park motor vehicles, motor vehicles begin to turn to the sides of the road to park. Because the number of motor vehicles is too large, and because there are no relevant departments to reasonably regulate and restrict roadside parking, there has been chaos in roadside parking, which will affect dynamic traffic in severe cases, making the speed of motor vehicles on urban roads Generally low, and sometimes serious traffic jams occur. How to make full use of the existing idle resources on the road, and reasonably and scientifically regulate the parking order on the roadside, and at the same time ensure 24-hour uninter...
