Embodiment 1
[0039] figure 1 It shows a schematic flow chart of a phase-consistent Hough transform wear lane line detection system and its implementation method in the preferred embodiment of the present invention. The example of the present invention develops an edge detection platform, and performs normalized stretching transformation and image grayscale transformation on the image , two-dimensional Fourier transform and phase consistency measurement technology; re-develop the signal enhancement platform, select the filter module through the frequency range of the image content, input the filtered image into the developed lane line extraction platform, and perform Hough transform and Set the local maximum value, and finally output the lane line detection.
[0040] The example of the present invention takes images of long-worn lane lines on the road. In the obtained image, due to the shooting angle, the parallel lane lines in the actual road appear to cross in the image. figure 2 A sche...
