Abstract

The invention provides a method for quickly detecting a human head, and the method comprises the steps: calculating a resolution image and the minimum and maximum radius images of a human head according to a calibration line; calculating edge point images and edge gradient vector images of the images; obtaining a Hough space image according to Hough voting; extracting candidate points of the human head; calculating the radius and confidence of candidate human heads, and obtaining candidate human head regions; carrying out the candidate human head regions; enabling the residual candidate human head regions to serve as human head detection regions, and outputting the residual candidate human head regions. The method achieves the quick detection of the human head, and can be used in pedestrian counting.

Description

technical field [0001] The invention relates to image processing and video monitoring, in particular to a method and device for head detection. Background technique [0002] Using pedestrian counting technology, it is possible to predict the pedestrian flow at a certain time in the future by analyzing the historical data of pedestrian flow. Therefore, pedestrian counting has various important applications in shopping malls, supermarkets, parks, buses and subways. The basic technology of pedestrian counting is to identify individual people in the crowd. In a crowded environment, due to mutual occlusion between people, it becomes difficult to accurately identify the entire human body. However, as long as the camera is installed at an appropriate angle, there is less occlusion between heads. Therefore, head detection technology has great practical value in the research of pedestrian counting. [0003] The Chinese invention patent application with the publication number CN10532...
