摘要

The present invention relates to a method detection and recognition of a traffic light based on feature extraction of a traffic light for processing an image received from the imaging unit mounted on the vehicle to determine the location and color of a traffic light in the image, a frame from the video image photographing device attention specifying the area according to the received input in sequence predetermined criteria by region of interest region setting step, noise and binarization to convert the color space, and filter the signal color, and black color within the region of interest, present in the filter frame a When the lights present in the correction step, the color of the signal, location of the signal of interest from the traffic light determination step and said light determination step of using the shape of the form and the traffic light to determine the light existence in the area of interest of the signal to the region to eliminate having a value of in the region of interest setting step, the light does not exist in the area of interest If directed to a method of detecting and recognizing a traffic light based on feature extraction of a traffic light, characterized in that to release formed by a region of interest comprises a region of interest comprising: reset performed from the region of interest setting step again.;
