Document Type and Number:
Japanese Patent JPH10513288
Kind Code:
A
Abstract:
A method and apparatus defines boundaries of the roadway and the lanes therein from images provided by video. The images of the roadway are analyzed by measuring motion between images and detecting edges within motion images to locate edges moving parallel to the motion of the objects, such as vehicles, thereby defining the approximate boundaries of a lane or roadway. A curve is then generated based on the approximate boundaries to define the boundaries of the lane or roadway.
