[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings. The method flow of the present invention is as follows: figure 1 As shown, the specific speed control process is as follows figure 2 shown.
[0038] 1. If image 3 As shown, traffic sign detection and recognition:
[0039] The first step: Affected by factors such as weather and actual road environment, the picture is prone to color blur and distortion after taking the frame. First, it is preprocessed to eliminate the influence of lighting, motion blur and noise (Wiener filter, histogram equalization) , and then based on the front vehicle and the driving situation of the collected image, the edge detection operator is used to detect the position L of the edge line of the right lane. 1 (Very effective in small traffic), and a simple template matching to roughly find the approximate position L of the left vehicle 2 (mainly for sections with large traffic flow...
