Visual analysis visitors flow rate statistical method and visual analysis visitors flow rate statistical equipment based on laser detection lines

Abstract

The invention discloses a visual analysis visitors flow rate statistical method and visual analysis visitors flow rate statistical equipment based on laser detection lines. The visual analysis visitors flow rate statistical method comprises the following steps of acquiring visitors access videos, which comprise two laser lines, of a certain passageway from a position above the head of a user by using a network camera; extracting the left laser line and the right laser line and using the left laser line and the right laser line as a left detection line and a right detection line to generate a height contour line; judging whether visitors pass through the passageway or not; counting the flow rate of the visitors who come in and go out from the passageway after information about access of the visitors is confirmed in a matched manner; and recording current time so as to count the number of the visitors of the certain passageway in a certain period and obtain the number of the visitors in a place through the difference between the number of the visitors of the beginning of the period and the number of the visitors of the ending of the period. By the visual analysis visitors flow rate statistical method, the number of the visitors who come in and go out from the certain passageway can be detected automatically and accurately. The visual analysis visitors flow rate statistical equipment consists of a plurality of detection units; and each detection unit comprises video acquiring equipment, laser equipment, network equipment, a computer or embedded processing equipment. By the visual analysis visitors flow rate statistical equipment, the visitors flow rate statistical precision is improved, the visitors flow rate statistical speed is increased, and walking directions of the visitors can be detected. The visual analysis visitors flow rate statistical equipment can be widely used for various entrances or public places.

Description

technical field

[0001] The invention relates to the field of people flow statistics at exits / entrances, in particular to a laser detection line-based visual analysis people flow statistics method and equipment. Background technique

[0002] The problem of people flow statistics is a frontier direction that has attracted much attention in the fields 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 the area and the flow density of people in the area in a timely manner, and provide data support for management, safety warning, and flow guidance.

[0003] Existing methods for counting people flow 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 judg...

[0048] The technical scheme that realizes the object of the present invention:

[0049] A method for visually analyzing people flow statistics based on laser detection lines, comprising the following steps:

[0050] 1) Collect video, use two inline lasers to project the left laser line and right laser line from the top of the head on the ground, and collect the video of people entering and exiting a certain entrance including the two laser lines through the network camera from the top of the head;

[0051] 2) Extract the detection line, and extract the left and right laser lines as the left and right two detection lines by performing video analysis on the collected video;

[0052] 3) To generate a height contour line, the detection line will break and deform during the process of people entering and leaving. Through video analysis, from the beginning of the detection line break to the end of the detection line break, that is, the entire process of people entering and exiting, ...
