Problems solved by technology

The block model-based method detects whether parking occurs by detecting changes in the block image area, and can quickly and accurately detect abnormal parking events in scenes with good light. Due to the complex and changeable weather conditions, the method based on the block model cannot detect abnormal parking events stably and effectively

Embodiment 1

[0039] Embodiment 1, the automatic detection method of parking on the expressway.

[0040] Refer to attached figure 1 .

[0041] The automatic detection method of the present invention is as figure 1 As shown, it specifically includes the following steps:

[0042] step 1:

[0043] In the specified expressway monitoring scene, set the detection area where parking is prohibited and the parking alarm time threshold; multiple closed detection areas can be set, and different parking alarm time thresholds can be set for different detection areas;

[0044] Step 2:

[0045] Target detection, to detect the foreground target in the scene;

[0046] First, establish a Gaussian background model;

[0047] Secondly, compare the current frame image with the background image, and if it conforms to the distribution of the background model, it is considered as the background, otherwise it is the foreground, thereby binarizing the current frame image;

[0048]

[0049] Among them, f t ...

Embodiment 2

[0077] Embodiment 2, an automatic detection device for parking on the expressway.

[0078] Refer to attached figure 2 .

[0079] The automatic detection device of the present invention is used for the above detection method, and specifically includes an image acquisition module 1, a rule setting module 2, a target detection module 3, a target tracking module 4, a trajectory analysis module 5 and a model update module 6, the image acquisition module 1 For collecting images and changes thereof in the monitoring scene on the expressway, the rule setting module 2 is used to set detection rules in step 1 of embodiment 1, and the target detection module 3 is used in step 2 of embodiment 1 Detecting the foreground target in the monitoring scene, the target tracking module 4 is used to track the detected foreground target in step 3 of embodiment 1, and the track analysis module 5 is used to track the detected foreground target in step 4 of embodiment 1 The trajectory of the foregro...

Abstract

The invention provides an automatic highway parking detection method which comprises the following steps: 1) range setting; 2) target detection; 3) target tracking; 4) trajectory analysis; and 5) monitoring scene background update. By analyzing the track of a vehicle target, three kinds of events, which are abnormal parking event, abnormal parking relieving event and normal driving event, are obtained through classification, and thus behaviors of a vehicle can be tracked and analyzed better. Through trajectory analysis of the vehicle target, different background model update strategies and update rates are adopted for happening regions of different kinds of events, thereby improving accuracy of target detection, improving accuracy of abnormal events and reducing false alarm rate.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to an automatic detection method and device for parking on expressways. Background technique [0002] With the development of social economy and the improvement of people's living standards, the number of urban motor vehicles has grown rapidly and is still growing. Infrastructures such as highways and urban roads are correspondingly on the fast-growing channel. At present, my country’s highways have exceeded 100,000 kilometers. However, due to the backwardness of management technology and supervision methods, traffic accidents occur frequently. Such reasons are important illegal acts that lead to accidents. Once these acts occur, and the danger signal cannot be quickly and effectively transmitted to the car behind, and the speed of the vehicle is reduced, it will easily lead to serious traffic accidents and threaten the safety of people's lives and property. Therefore, how to qui...
