Problems solved by technology
As far as the traditional technology using image processing technology for lane recognition is concerned, it needs to go through the problem of setting the region of interest and multiple stages of image processing, and its computational load is relatively increased
Moreover, if the unrecognized or misrecognized lanes are strengthened by forming multiple filters, even if one lane is recognized, the filtering level of the lanes on both sides will be improved, resulting in a decrease in the lane recognition rate.

The present invention proposes a method and device for identifying lanes using unequal weighted values in the method for identifying lanes using unequal weighted values to improve the lane recognition rate by using multiple filters, and a method and device for controlling a lane keeping assist system using the method and device. The device for identifying lanes using unequal weighted values of the present invention is a device for identifying lanes using unequal weighted values from the lane recognition method using multiple filters, including: an image recognition unit that recognizes left and right lanes and calculates the left and right lanes. The offset and reliability of the right lane; the recognition judgment part judges whether there is unrecognized or misrecognized information in the identified left and right lane information; the main filter, based on whether it is unrecognized Or in the judgment of misrecognition, the weighted values of several low-pass filters (LPF, Low Pass Filler) are changed, and a corrected lane is generated by using the signals of the low-pass filters to which the changed weighted values are applied.
Description
technical field [0001] The present invention relates to a method and device for identifying lanes using unequal weighted values and a control method and device for a lane keeping assist system using the method and device, in particular to using unequal weighted values in the lane recognition method using multiple filters to improve the lane recognition rate A lane recognition method and device using unequal weighted values, and a lane keeping assist system control method and device using the method and device. Background technique [0002] Lane Keeping Assist System (LKAS: Lane Keeping Assistance System) is a technology that uses cameras to identify lanes and implement automatic steering. Based on camera image processing, it measures the width of the lane, the lateral position of the vehicle on the lane, the distance from the lanes on both sides, and the shape of the lane. The radius of curvature is used to control the vehicle using the obtained vehicle position and road...
