Abstract

The invention provides a method and a device for detecting a road dividing object. The method comprises the steps of: acquiring an image including a road region; detecting a road dividing object region in the image; detecting feature points of the road dividing object in the road dividing object region in the image; and determining the road dividing object according to the detected feature points of the road dividing object in the road dividing object region. The method and the device for detecting the road dividing object can reduce the complexity of lane line modeling and post-processing algorithms, and can enhance the accuracy degree of lane line detection.

Description

technical field [0001] The present invention relates to the field of object detection, and more particularly to a method and device for detecting road segment objects. Background technique [0002] The application of driver assistance systems is becoming more and more popular. The road or lane warning system (Lane / Roaddetection warning, LDW / RDW) is a subsystem of the driving assistance system, which can avoid collisions and determine the driving direction more accurately. Road or lane detection is very critical for LDW / RDW systems, and further processing, such as warning, is possible only on the basis of knowing the road information. Generally, roads or lanes are detected by detecting road dividers. [0003] Road dividers include lane lines, shoulder stones, fences, and other objects that can identify road areas and lanes, and lane lines can include white lines, yellow lines, and so on. [0004] In existing methods, when detecting lane lines, the specific position of the ...
