Embodiment Construction
[0037] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0038] The experimental platform is win10, the simulation library is opencv 1.0, and the road environment is part of the Beijing-Shanghai Expressway. Firstly, the image is preprocessed, and the lower 1 / 3 part of the image is taken as the area of sensitivity (AOI); since the road line is normally white, the color information in the image can be removed, and the grayscale image can be extracted to obtain the grayscale image as shown in Fig. figure 2 shown.
[0039] Next, threshold the grayscale image and select the 160×80 road surface window in the AOI area to count its mean and variance, suc...
