Embodiment

[0035] like figure 1 Shown, a kind of lane departure detection method, this detection method comprises the following steps:

[0036] Step 1) Use the four cameras installed on the vehicle body to detect lane lines, and the vehicle speed sensor collects the vehicle speed at the same time.

[0037] Carrying out lane line detection using four cameras arranged on the vehicle body includes the following steps: step 11) multiple cameras take images; step 12) segment the images taken by each camera into perception areas respectively, and intercept road surface information images; step 13) according to The gray value difference between the lane line and the road surface, processing each road surface information image to obtain the corresponding lane line information respectively; step 14) adopts confidence calculation, and selects the lane line information with the highest confidence level as the most accurate lane line information. Confidence calculations specifically include the fo...

Abstract

The invention relates to a novel lane line deviation detection method and a novel lane line deviation detection device. The method comprises the following steps of: detecting a lane line by using a plurality of cameras arranged on a vehicle body, and simultaneously, acquiring the running speed of a vehicle by using a vehicle speed sensor; acquiring state information of the vehicle in a lane according to calibration results of the cameras arranged on the side of the vehicle body and the positions of the lane line in images; and performing lane deviation evaluation, and judging whether the vehicle can deviate from the lane. The device comprises a plurality of cameras, the vehicle speed sensor and a processor, wherein a plurality of cameras are arranged on the vehicle body; and a plurality of cameras and the vehicle speed sensor are respectively connected with the processor. Compared with the prior art, the method and the device have the advantages that the method and the device are wide in application range, the lane line detection accuracy and the vehicle state detection accuracy are high, and the real-time performance is high.

Description

technical field [0001] The invention relates to a lane deviation detection method and device, in particular to a lane deviation detection method and device. Background technique [0002] Lane departure detection refers to knowing the route through on-board sensors, judging the vehicle's own position in the lane, and predicting whether the vehicle is in danger of deviating from the lane. Most of the lane departure detection systems use a single forward-looking camera as the sensor for data collection. [0003] For example: Chinese invention patent application number 201010253424.0 discloses a lane deviation recognition method, the method includes the following steps: using a camera to capture images; segmenting the captured images into regions of interest, and intercepting the road information at the bottom of the images image; preprocessing the road information image; detecting the lane line; tracking the lane line; detecting whether the vehicle deviates from the lane line ...
