Abstract

The invention discloses a pedestrian flow statistics method and a statistics system based on human body HOG characteristics. Wherein, the statistical method includes: setting a database for storing negative samples, setting a detection area, and setting a virtual gate with a preset width in the detection area. The detection area is monitored to obtain a video sequence comprising a plurality of sequentially arranged video images. Extract HOG features of all objects in each of the first N video images, where N≥2. Every time a HOG feature is extracted, it is judged whether the HOG feature matches the negative sample. If the HOG feature matches the negative sample, the target corresponding to the HOG feature is eliminated, otherwise the next HOG feature is matched. After the HOG feature extraction of all video images is completed, all objects in each video image are extracted. The same target is arranged in the order of video images to obtain a positive sample video sequence, so that a set to be determined with multiple positive sample video sequences is obtained.

Description

technical field [0001] The invention relates to the technical fields of video monitoring and image processing and analysis, in particular to a pedestrian flow statistics method and system based on human body HOG characteristics. Background technique [0002] With the continuous progress of society, the application range of video surveillance system is getting wider and wider. The flow of pedestrians entering and exiting places such as roads, squares, shopping malls, bus stations, and subways is of great significance to decision makers in the above places. Therefore, pedestrian flow statistics methods such as artificial statistics, infrared statistics and weight statistics have appeared. However, these statistical methods have defects such as high cost, low accuracy, and narrow application range. With the development of video surveillance technology, there has been a method of tracking pedestrian traffic based on human characteristics. [0003] The patent application numbe...
