[0049]In order to further understand the content, features and effects of the present invention, the implementation method and principle of the present invention will be further described below in conjunction with examples and accompanying drawings.
[0050] According to the lane detection method implemented in the present invention, such as figure 1 As shown, it includes the following steps:
[0051] Step 1, using the vehicle-mounted camera to acquire road images;
[0052] Step 2, image preprocessing is carried out to the image that step 1 acquires: first intercept the lower half area of road image (the road image is divided into two from the middle, and the lower half is the ROI area, such as Figure 11 Shown in (a) and (b)) as the initial region of interest (Region of Interest, ROI), and then perform grayscale processing, color space transformation, gradient threshold filtering, and color space threshold filtering on the region, and finally obtain multi-thresholding Fil...
