Problems solved by technology

[0004] Traditional coping strategies are based on rough predictions based on past experience data. It is impossible to understand the current number of people at the current crowded point and the key data such as the number of people flocking to the crowded point and the speed of people in real time. The response is poor.

Embodiment approach

[0033] This patent is a human flow video detection and analysis system, an implementation of the system is as follows:

[0034] 1. Human figure judgment: Human figure basic template combined with human motion posture template to distinguish human from objects and animals;

[0035] Specifically, this system selects 10 adult men and women, and 10 underage children. A total of 40 men and women of different ages, heights, and widths are selected as the basic humanoid template. The template is not real. The human form is a set of geometric feature data of the human form; at the same time, this system divides the human body into 8 parts, and for each part of the body, 12 typical human postures are produced, and a total of 96 typical human shapes are generated. Movement posture, then combining human figure and movement posture, a total of 3840 standard human figure posture templates are generated, such as figure 1 ; Thereafter, the captured moving objects are automatically applied t...

Abstract

The invention discloses a people flow video detection and analysis system. The people flow video detection and analysis system comprises hardware equipment, a software engine and a template database, wherein the hardware equipment comprises a computer, video input equipment and network equipment; the software engine comprises a recognition and capture engine, a framing engine, a projection engine, and a 3D trajectory tracking engine; and the template database comprises a human shape foundation template and a human motion attitude template. The people flow video detection and analysis system provided by the invention calculates the people flow volume, the people flow density, the direction of travel of the people flow, and the average speed of the people flow by making a statistic of the above mentioned data of each person.

Description

technical field [0001] The invention relates to a computer-aided biological feature recognition and analysis system, more specifically, a human flow video detection and analysis system. Background technique [0002] With the development of modern society, the flow of people is becoming more and more dense. There are more and more cities with a population of tens of millions, which leads to a particularly dense flow of people in these cities at specific times and specific locations every day, especially transportation hubs, subway transfer stations, and tourist attractions. [0003] The gathering of people will inevitably lead to an increase in various risks. For example, it is recorded in "Risk Analysis and Prevention and Control of Crowd Stampede Accidents": When the crowd density exceeds 5 people / m 2 When it is time, it can be regarded as a continuous medium. Disturbances in the crowd, such as sudden power outages, entering narrow entrances and exits from a spacious space...
