Embodiment Construction
[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0046]The basic hardware condition needed to realize the system structure of the present invention is: a main frequency is 2.4GHZ, and the internal memory is a computer with 1G, and the required software condition is: the programming environment is Visual C++6.0.
[0047] A lane line detection method based on feature point piecewise linear fitting, the specific steps are as follows:
[0048] Step (1): Start, read the image.
[0049] Step (2): Extract the region of interest in the image, and save the image of the region of interest to the corresponding location. Mainly by clipping the image, the effective road area in the structured road image is extracted, that is, the image of the vehicle's drivable area, and the non-road area map is deleted for subsequent processing.
[0050] Step (3): Use Sobel operator to extract the edge image of the extracted re...
