Abstract

The invention discloses an early warning and diversion method and system for intelligent anti-crowding stamping. The method comprises: collecting images on each road segment in the venue at a preset acquisition rate by using a distributed camera and uploading the images to a server; performing gridding division on the images and performing personal flow detection through object center identification in the grid set, and calibrating the number and position information of the images; obtaining a current crowd speed threshold of the venue according to the load information; calculating the path and the speed of the image in the position; generating a personal flow model of each road segment scene, and generating a personal flow density map of the venue; obtaining the crowd speed of the currentcrowd in each road segment scene from the personal flow density map, and automatically generating an alarm signal for early warning and diversion of the crowding stamping when the crowd speed reachesor exceeds the current crowd speed threshold. According to the early warning and diversion method and system for intelligent anti-crowding stamping, the traffic efficiency is greatly improved, and the occurrence of crowding and stamping events is prevented.

Description

technical field [0001] The present invention relates to the technical field of anti-crowding stampede, and more specifically, to an intelligent anti-crowding stampede warning and diversion method and system. Background technique [0002] With the rapid development of social economy, people's living standards are constantly improving, and people go to and from public places more and more frequently, which may cause crowding and stampede incidents. Stampede accidents refer to places where people are relatively dense, such as stadiums, theaters, schools, narrow streets, stairs and other public places. Due to the loss of control of the scene order, crowding and chaos occur, resulting in a large number of people being crushed, suffocated or trampled to death. accident. Stampede accidents on primary and secondary school campuses are likely to cause mass deaths and injuries, and most of the victims are students. They have received widespread attention from the society and are high...
