specific Embodiment
[0072] A specific embodiment of the present invention is as follows:
[0073] S1, using the camera to obtain a real-time image with effective pixels of 320×240 when the vehicle is driving;
[0074] S2. After the real-time image is processed in the preset effective area of 320×160, a binarized image of the real-time image in the effective area is obtained:
[0075] S21. Refer to figure 1 As shown, the real-time image is intercepted in the area image within the effective area of 320×160; here, the effective area refers to the part of the image in the real-time image that contains lane information;
[0076] S22. Carrying out a median filter operation on the regional image to remove noise brought about during image acquisition and transmission:
[0077] f(x,y)=median{S f(x,y)}
[0078] In the above formula, S f(x,y) It is a 3×3 small area near the point f(x, y), and the median filter is to use the pixel average value of the 3×3 small area where a certain point is located ...
