Problems solved by technology

[0005] This method is to count the number of people in the entire area, and it is difficult to accurately make a crowded stampede warning, because for an area, some people in this area may be overcrowded, but due to the number of people in the entire area If the number does not reach the threshold and no stampede warning is issued, it is likely to lead to a stampede event

Abstract

The invention discloses a mesh generation-based crowded stampede pre-warning method and device. The method comprises the following steps of: determining a to-be-monitored target area; carrying out mesh generation on the target area according to a preset mesh generation rule; determining a body posture dip angle warning value of each mesh; judging a size relationship between a body posture dip angle of a staff in each mesh and the body posture dip angle pre-warning value of the mesh in a process of monitoring the target area; and determining whether to output crowding pre-warning information according to a judging result. By applying the technical scheme provided by embodiments of the invention, crowded stampede pre-warning can be carried out timely and correctly, so that the crowded stampede events are avoided.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a method and device for early warning of crowding and stampede based on grid division. Background technique [0002] During large-scale activities such as festival celebrations, sports events, and religious activities, crowding and stampede incidents are likely to occur in many crowded areas due to the large passenger flow and high passenger flow density, causing casualties. [0003] For example, on December 31, 2014, a large number of tourists and citizens gathered in the Bund area of ​​Huangpu District, Shanghai to welcome the New Year. Due to the hedging of the flow of people entering and exiting on the north and south steps of the path leading to the viewing platform from Chen Yi Square, some people fell and occurred. The stampede caused 36 deaths and 49 injuries. On February 5, 2004, during the Lantern Festival Lantern Festival in Mihong Park in Miyun County, Beijing, du...
