License plate location method based on integral channel features

The invention relates to the field of computer vision, and particularly relates to a license plate location method based on integral channel features. For license plate location recognition in intelligent video monitoring, the license plate location method comprises the steps of license plate sample feature extraction training and feature organization, and license plate detection location. According to the first step, the original license plate image is manually pulled out; the integral channel features are extracted; and a detector is trained based on an Adaboost algorithm. According to the second step, a sliding window method is used to scan a target image to acquire an initially located license plate image; tilt correction based on Hough transform is carried out on the initially located result of the image which is output by the detector and undergoes non-maximum value suppression processing; and an output license plate after secondary location is input into the detector to acquire a final license plate lo
