Abstract:
Method for detecting road edges in a road of travel for clear path detection. Input images are captured at various time step frames. An illumination intensity image and a yellow image are generated from the captured image. Edge analysis is performed. The line candidates identified in a next frame are tracked. A vanishing point is estimated in the next frame based on the tracked line candidates. Respective line candidates are selected in the next frame. A region of interest is identified in the captured image for each line candidate. Features relating to the line candidate are extracted from the region of interest and input to a classifier. The classifier assigns a confidence value to the line candidate identifying a probability of whether the line candidate is a road edge. The potential line candidate is identified as a reliable road edge if the confidence value is greater than a predetermined value.
