Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing:
[0029] With the increasing improvement of the road monitoring system, a large number of complex traffic videos have increased the work pressure of the traffic police department. Therefore, the establishment of an intelligent traffic monitoring model has become the key to the automation of road condition monitoring.
[0030] The present invention first extracts the background image and the foreground image of the video based on the improved Gaussian mixture model method and the background frame difference method. Secondly, in the traffic environment under natural light, vehicle shadows affect vehicle detection, which can easily cause missed and multiple detections of vehicles. A shadow elimination algorithm based on lab color space transformation is used. Next, in order to get the double yellow line area in the video, use the background Figure II Value, morphological proce...

The invention provides an automatic detection method for pressing double yellow lines by a vehicle. The method comprises the following steps: S1, obtaining a road monitoring video image; S2, based on a Gaussian mixture model method and a background frame difference method, extracting road background and foreground moving targets; S3, removing the shadow of the foreground moving target based on an LAB color space image shadow detection and removal method; S4, distinguishing a person from a vehicle target; S5, extracting a double-yellow-line area in the road background; and S6, detecting that the vehicle presses the double yellow lines. The invention is suitable for detecting that the vehicle presses the double yellow lines under the road monitoring video, the position information of the vehicle and the yellow lines is obtained through operations such as background modeling, vehicle and pedestrian distinguishing and double yellow line position extraction, and real-time detection on the traffic accident that the vehicle suddenly presses the double yellow lines on the road is achieved. The invention is strong in anti-interference capability and good in robustness, and can realize the automatic detection of the vehicle pressing the double yellow lines in a natural scene.
Description
technical field [0001] The invention belongs to the field of image processing, and in particular relates to an automatic detection method for double yellow lines on a vehicle. Background technique [0002] In the process of building a safe city, safety is an important task in the daily management of the government. With the construction of urban alarm and monitoring systems, the analysis of monitoring data is becoming increasingly important. Violating the regulations and crossing the yellow line in the center of the road is a key cause of traffic safety accidents. It not only easily causes the danger of vehicle collision or friction, but also easily causes road congestion. Once a traffic safety accident occurs, it is a major traffic safety accident. great. [0003] In traffic safety, vehicles pressing double yellow lines is one of traffic violations. Real-time and accurate detection of vehicles pressing double yellow lines is of great significance to intelligent transporta...
