Intersection multi-lane calibration method based on perspective transformation
Disclosed is an intersection multi-lane calibration method based on perspective transformation. The intersection multi-lane calibration method comprises the following steps that 1, an image with an obvious lane line is selected from a monitor video of an intersection; 2, edge extraction is performed through a Canny operator on the basis of the selected image, and then n straight line segments are extracted by means of Hough transformation; 3, horizontal line segment sets H and vertical line segment sets S are obtained according to slopes; 4, the sets H and S obtained in the step 3 are screened preliminarily; 5, the H and S finally obtained from the step 4 are marked as H' and S', and the line segments are further filtered; 6, a red light line is determined in H'' and S'' is further filtered so as to determine a lane line; 7, the line segment representing the lane line is found out from the set S''' obtained from the step 6.
