Pedestrian flow counting method and device based on infrared temperature measurement sensor

Abstract

The invention discloses a pedestrian flow counting method and a pedestrian flow counting device based on an infrared temperature measurement sensor. According to the pedestrian flow counting method, 6 paths of temperature data on a same vertical line are acquired through an infrared temperature measurement sensing part which is placed on the side of an access, whether a person passes by is judged through analyzing the temperature data, whether the incoming and outgoing of the person end is judged by detecting a time interval when nobody passes, thus the incoming and outgoing information can be judged, control and measurement units transmit the incoming and outgoing information of people to an upper machine in real time, and the upper machine can record the current time, count number of people passing by an entrance and number of people passing by an exit within a time period and obtain the number of people in a place through difference between the two numbers, thereby achieving the automatic, accurate and reliable detection of number of the incoming and outgoing people. The pedestrian flow counting device comprises the infrared temperature measurement sensing part, a temperature acquisition / analysis part, a network device and a computer or an embedded processing device serving as the upper machine. The pedestrian flow counting improves the pedestrian flow counting stabilizability, precision and speed, and can be widely applied to entrances or public places.

Description

technical field [0001] The invention relates to the field of people flow statistics at exit / entry, in particular to a people flow statistics method and device based on an infrared temperature measurement sensor. Background technique [0002] The problem of people flow statistics is a frontier direction that has attracted much attention in the field of computer vision and intelligent security monitoring in recent years. It can be widely used in public places such as shopping malls, tourist attractions, exhibition halls, etc., to obtain the current flow of people entering and leaving and the density of people in the area in time, and provide data support for management, safety warning, and flow guidance. [0003] The existing people flow statistics methods mainly include blocking judgment detection methods based on infrared and ultrasonic technology and humanoid feature detection methods based on image and video processing. It is often difficult to judge the true and false hu...

AI Technical Summary

Problems solved by technology

It is often difficult to judge the true and false human targets when counting people through blocking judgment based on infrared and ultrasonic technology; it is often difficult to obtain the motion parameters of the human body by modeling the complete human body with the humanoid feature detection method based on image and video processing. And once there is a crowded situation, the situation of the human body in the image will be more complicated, the detection is very difficult, and the accuracy rate is not high. It can only detect the passing humanoid objects, and cannot judge whether it is a real person or a dummy.
