Abstract

The invention provides a people counting method based on video flowing image processing. The method comprises the following steps of: S1, acquiring a video flowing image of a monitoring region to be used as an input image; S2, removing noises in the input image by using median filter processing, and carrying out histogram equalization processing to improve the contrast of the input image obtained in the step S1; S3, segmenting a motion target region through using a Gaussian background modeling method according to the input image (obtained in the step S2) with the high contrast; S4, carrying out erosion smoothing operation on the segmented motion target region through an erosion smoothing operator to obtain a motion target outline; S5, scanning the motion target outline obtained in the step S4 by using a plurality of ring modules, carrying out concyclic overlap ratio HO calculation to extract human head outlines; and S6, counting the human head outlines to obtain the number of people. By using people counting method based on the video flowing image processing, the efficiency and the accuracy degree of counting the number of the people in real time in a public area are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of video image processing and recognition, in particular to a method for counting people based on video stream image processing. Background technique [0002] People counting is an important application of moving target detection and tracking technology, and it is also a very active new field in today's intelligent vision system research. The traditional people counting method is to use manual counting or artificial electronic equipment to trigger counting. With the advent of the information age, it is very necessary to develop an intelligent people counting method. [0003] Intelligent people counting technology is to use computer vision and image processing methods to establish an intelligent management system, and to realize pedestrian counting by analyzing the video sequence recorded by the camera without human intervention or with little intervention. Positioning, tracking and accurate counting of ...
