Vehicle blind area division method based on image processing

According to the content of the invention, a vehicle blind area division method based on image processing is realized, defects of detection of other vehicle blind areas are optimized, visualization of the vehicle blind area is realized, and a foundation is laid for monitoring dangerous conditions of the blind area. According to the specific technical scheme, the method comprises the following four parts: original image preprocessing, road surface region division, road surface region edge point extraction and lane line detection. Original image preprocessing: in order to better divide a blind area subsequently, preprocessing the image, including graying processing, image denoising, image enhancement and other operations; road surface region division: detecting a boundary between a road surface region and a non-road surface region by detecting road vanishing points, and further dividing the road surface region; road surface area edge point detection: extracting feature points of the road surface area through an
