Problems solved by technology

[0004] However, the existing technology can only realize the video monitoring of the no-stop area, but still needs to manually browse the video or on-site monitoring, and there is still a problem of manpower consumption
Although some literature has conducted some research on the situation of illegal parking on the road, there is still no feasible plan
[0005] In summary, the video surveillance system in the prior art cannot automatically detect illegal parking

Embodiment 1

[0057] The first embodiment of the present invention provides a method for detecting illegal parking, see figure 1 Shown, including steps:

[0058] In step S110, the forbidden area of ​​each frame of the image in the captured video sequence is designated.

[0059] Take the video sequence I n (x, y) is used as the background image, and the forbidden road section or area B (x, y) is pointed out through the area setting; the designation of the forbidden area is the process of obtaining the position information of the boundary of the forbidden area.

[0060] Step S111: Perform foreground detection, and detect the target in the foreground.

[0061] Various related algorithms can be used for foreground detection, such as a mixed Gaussian background model, SACON (SAMPLE CONSENSUS), etc., which are not listed in this embodiment.

[0062] In this embodiment, the first frame of the captured video image sequence is used as the initial background, and the binary image of the foreground target is e...

Embodiment 2

[0070] The second embodiment of the present invention provides a method for detecting illegal parking, see figure 2 Shown, including steps:

[0071] In step S210, the forbidden area of ​​each frame of the image in the captured video sequence is designated.

[0072] Step S211: Perform foreground detection using the difference method, and detect the target in the foreground.

[0073] In this embodiment, the difference method is used to model the background of the forbidden road section or area, and the foreground target entering the forbidden road section or area is extracted.

[0074] Take video image sequence I n The first frame of (x, y) is taken as the initial background, and the current frame P(x, y) and its continuous video image data are subtracted using the difference method. The result is the extracted binary image T(x ,y);

[0075]

[0076] Among them, B (x，y） Is the background frame, and n is the threshold of the distance between the front and rear frames.

[0077] Preferably,...

Embodiment 3

[0124] The third embodiment of the present invention provides an illegal parking detection device, see Figure 4 As shown, it includes a designated module, a foreground detection module, a tracking module, a drawing module, and a judgment module.

[0125] The designation module is used to designate the forbidden area of ​​each frame of the image in the collected video sequence; the foreground detection module is used to perform foreground detection to detect the target in the foreground; the tracking module is used to track and detect To determine whether there is a target entering the prohibited area; the drawing module is used to draw the color histogram in the prohibited area; the judgment module is used to monitor the continuous change of the color histogram Determine whether the duration is greater than the preset time. If yes, it is determined that there is illegal parking in the no-parking area, if not, it is determined that there is no illegal parking in the no-parking ar...

Abstract

The invention provides a detection method of parking against rules. The detection method of the parking against the rules comprises the following steps: appointing a forbidden parking area of each frame of image in a collected video sequence; conducting a prospect detection to detect a goal of the prospect; following the detected goal to judge whether a target enters into the forbidden parking area, if yes, painting a color histogram within the range of the forbidden parking area, if no, conducting the detection continuously;and monitoring the duration of the color histogram after the color histogram changes to judge whether the duration is longer than the preset time, if yes, judging that a car against the rules parks in the forbidden parking area, if no, no car against the rules parks in the forbidden parking area. The invention further provides a detection device of parking against the rules. The detection device comprises an appointing module, a prospect detection module, a following module, a painting module and a judging module. The detection method and the device of parking against the rules can effectively achieve the automatic detection of the parking against the rules.

Description

Technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for detecting illegal parking. Background technique [0002] Because illegal parking is prone to traffic accidents, every country has set up no-parking sections to prohibit random parking. At present, most illegal parking at home and abroad adopts manual monitoring methods, and collects illegal information of illegal vehicles at fixed points, which consumes a lot of manpower, material and financial resources. [0003] With the continuous development of digital image processing technology, video surveillance systems have become an important part of maintaining public order and strengthening social management. Video surveillance systems based on image processing are increasingly used in traffic control. [0004] However, in the prior art, only video surveillance of prohibited areas can be realized, but it still needs to manually browse the video or on-site surv...
