Title:

VEHICLE ILLEGAL LANE CHANGE RECOGNITION METHOD BASED ON TWO STAGES

Document Type and Number:

WIPO Patent Application WO/2023/103204

Kind Code:

A1

Abstract:

Disclosed in the present invention is a vehicle illegal lane change recognition method based on two stages. The method comprises the steps of: starting a vehicle and a camera, and reading a camera image in real time as an input; processing the input image to detect a lane line; comparing the change conditions of base points of the lane line, determining whether a vehicle changes a lane and the lane change direction, if the vehicle does not change a lane, re-reading the image for recognition, and if the vehicle changes a lane, capturing a lane-changing lane line image for the next step; and applying a lane line type prediction model to a device for recognizing a lane-changing lane line, if the recognition result is one of a solid line, solid and dash lines or double solid lines, determining that the vehicle illegally changes the lane, and sending an alarm prompt. According to the present invention, the lane line, the lane change of the vehicle, and the type of the lane-changing lane line can be recognized. A residual module is improved, so that the recognition accuracy of an algorithm is improved; detection and recognition of the lane lines can be rapidly completed, and transplantation of an embedded application is facilitated.
