[0043] Using the method of the present invention, first use the C++ language to write lane detection software; then install the camera inside the front window of the car, calibrate various parameters of the camera, and collect the front image during the driving of the vehicle; The captured original image of the vehicle is input into the lane detection software as source data for processing; the experiment collects hundreds of source images under several driving conditions. When the driving is relatively stable, the success rate of the lane detection algorithm of the present invention is greater than 90 %, when the image is severely blurred due to violent bumps, the lane detection success rate can also reach more than 60%. For a higher resolution original image with a size of 656×491, the average processing time for each image is about 0.3s, and the operating environment is WinXP 2GHz, the compiler is Visual Studio 2005C++.
[0044] To sum up, the method of the present invention ma...
