Vehicle lane-changing violation detection method based on video detection technology

Abstract

The invention discloses a vehicle lane-changing violation detection method based on the video detection technology, and the method comprises the steps: judging whether a vehicle passes across a solid lane line where crossing and lane changing are forbidden or not through capturing a continuous single-frame image sequence, so as to detect the lane-changing violation information of the vehicle; employing Hough transformation for line direction for the lane line, and judging whether the lane line is a solid lane line or a virtual lane line according to the number of pixels of the lane line; employing a background difference method and a matching method based on vehicle models to carry out the recognition of the vehicle; recognizing the information of the vehicle when the target vehicle passes across the solid lane line, recording and storing video information, and transmitting the suspected violation video information to a background server for checking and confirmation. The method irons out the defects of a conventional detection mode, achieves the real-time collection and detection of the lane-changing violation information of the vehicle based on the technologies of imaging processing, image recognition and video detection, improves the detection precision, avoids the external interference impact, and reduces the detection cost.

Description

technical field [0001] The invention relates to a detection method for vehicle illegal lane change based on video detection technology. Background technique [0002] With the rapid development of China's economy and the acceleration of urbanization, the number of cars has also increased rapidly, which has brought about a serious problem of serious urban traffic congestion, leading to frequent traffic accidents. According to data, 70% of traffic accidents are caused by abnormal driving behaviors of drivers, including illegal driving and fatigue driving. Among them, changing lanes illegally is a very common traffic violation, and its harm is huge, so the detection of illegal lane changing of vehicles is particularly important. [0003] Illegal lane changing of vehicles means that the vehicle is driving in a certain lane and suddenly changes lanes to the adjacent lane when lane changing is prohibited. The traditional detection methods for illegal lane changes of vehicles main...

Problems solved by technology

[0004] Video surveillance is to install cameras at fixed locations to monitor vehicle driving behavior. This method is costly and inefficient, and is greatly affected by human subjective factors, so the information is not reliable.

[0005] The ground sense coil method is to bury the ground sense coil in some special road sections and mark the forbidden lane change area. When the vehicle passes by, the metal body will cut the magnetic induction line of the ground sense coil, thereby generating induced electromotive force to detect the vehicle's illegal change. However, this method is not only costly, but also has great limitations, such as the need to destroy the existing road surface when installing the ground induction coil, and it is inconvenient to maintain

[0006] Therefore, both video surveillance and ground sensing coils have certain misjudgments and limitations in the detection of vehicle illegal lane changes. The existing technology partially solves the problem of vehicle illegal lane changes, but it cannot detect all vehicles within the video range in real time. Lane change
