We designed a smart car with the whole intelligence system independently which could run on the grid and capture the specific color cylinder. The crucial problem is to design a robust and real-time line and corner detector on a single-chip microcomputer. To solve it, we implemented the edge detection based on Hough transform, which performed well on the simple background.
