Description

Crowd estimation device

Technical Field

The utility model belongs to the image equipment field, especially, crowded estimation device of crowd.

Background

The traditional approach for guaranteeing the crowd safety is mainly that people monitor a certain scene through videos, the crowd state is judged subjectively, when the crowd density exceeds a certain degree, early warning is carried out, and meanwhile field workers are informed to close the entrance where the crowd is rushing out a large number of people. At present, the crowding degree can be automatically judged by using images shot by video monitoring, and quantitative scientific management of people is realized. However, such camera chips have high power consumption and high heat generation, and the service life of the camera is shortened if the heat cannot be effectively conducted.
