Problems solved by technology

The algorithm based on the straight line model mainly uses the standard Hough transform and its improved form to detect the straight line on the edge features obtained by image preprocessing. However, the problem is that the detection of the edge has a strong dependence. In many road scenes , due to the existence of vehicl...

Abstract

The invention provides a lane deviation detection method and device. The method comprises the following steps: obtaining a video image of the condition of a road ahead of a running vehicle; obtaining an edge mapping image of the video image; obtaining multiple peak points in the edge mapping image; obtaining lane lines according to the multiple peak points; and detecting the lane deviation according to the lane lines. According to the method provided by the embodiment of the invention, the video image of the condition of the road ahead of the running vehicle is obtained in real time, the lane lines are obtained through computing processing, the lane deviation is detected and early warning is carried out according to the lane lines, the method can adapt to days and nights and various complex road conditions, is low in computation complexity, and good in timeliness, and driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a lane deviation detection method and device. Background technique [0002] With the rapid development of the modern transportation industry and the vehicle industry, the mileage of highways and the number of vehicles are also increasing rapidly. At the same time, the number of traffic accidents that occur when vehicles are driving at high speeds is also increasing rapidly. The direct or indirect causes of traffic accidents include people, vehicles, roads and various environmental factors. Among them, driver's operating errors in fatigue driving, drunk driving and other inattentive situations are the main factors causing major traffic accidents. Furthermore, the proportion of major traffic accidents caused by vehicle deviation from the lane is very large. For example, according to the estimates of the U.S. Federal Highway Administration, 44% of all fatal traffic accidents in th...
