Abstract

The invention relates to a method for detecting a narrow road, which includes calculating the relative height of a point from a distance measuring sensor to the ground based on distance information. The left boundary point and the right boundary point where the relative height difference of adjacent points becomes the largest are obtained. When the relative height difference between the left boundary point and the right boundary point is greater than or equal to the reference value, the road boundary line of the driving road is obtained based on the left boundary point and the right boundary point according to the moving track of the vehicle. The road width of the traveling road is calculated based on the road boundary line. Whether or not the road on which the vehicle is traveling is a narrow road is detected based on the road width.

Description

technical field [0001] The invention relates to a method, device and system for detecting narrow roads. Background technique [0002] Recently, an advanced driver assistance system (ADAS) has attracted the attention of the vehicle industry greatly. The ADAS is a system that senses a dangerous situation occurring while driving a vehicle by using sensors installed in the vehicle, and deals with the dangerous situation to ensure the safety of a driver and provide convenience to the driver. [0003] When driving a vehicle on a protruding narrow road, the driver may not distinguish the boundary of the road well, making it difficult for the driver to steer the vehicle, and the risk of an accident increases. Contents of the invention [0004] Therefore, the present invention serves to solve the above-mentioned problems occurring in the prior art while fully retaining the advantages achieved by the prior art. [0005] One object to be achieved by the present invention is to prov...
