Title:
LANE MARKING RECOGNITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/109999
Kind Code:
A1
Abstract:
The present invention implements a lane marking recognition device which is capable of determining, with high accuracy, a line type of a lane marking on a road surface. In step 301, a feature amount is extracted from an image captured by each camera. This corresponds to a process of a feature point extraction unit. In the next step 302, the extracted feature amount is transformed to that of overhead coordinates that are common coordinates. This corresponds to a process of a coordinate transformation unit. Next, in step 303, a camera to be selected is determined. This is a process of a camera determination unit. Next, in step 304, a state transition is determined at an appearance position of the feature point on the overhead coordinates by using feature point coordinates of the camera selected in step 303. This is a process of a state transition determination unit. Finally, in step 305, a line type is determined. This is a process of a line type determination unit.
