Anti-tailing system using multi-person detection algorithm based on gait pattern tracking

Abstract

The invention discloses an anti-tailing system using a multi-person detection algorithm based on gait pattern tracking, which comprises a central control module, a data processing module, an information prompting module, an anti-tailing channel, an infrared correlation sensor and blocking devices at an outlet and an inlet of the anti-tailing channel, wherein the anti-tailing channel comprises the inlet and the outlet, and the blocking devices for blocking people from entering and passing are arranged at the inlet and the outlet of the anti-tailing channel. The anti-tailing system using the multi-person detection algorithm based on the gait pattern tracking can carry out accurate and timely judgment on the tailing phenomenon and reduce and even avoid the intervention of staff on duty, and has the advantages of high accuracy, low increased cost and capability of reducing maintenance cost.

Description

technical field [0001] The invention relates to a system for measuring people passing through a target passage, in particular to an anti-tailgating system based on a multi-person detection algorithm based on gait pattern tracking that can automatically judge whether people passing through a certain passage appear to be trailing. Background technique [0002] In some special industries such as roads, railways, and air passenger transport, in order to ensure the safety of vehicles, or in some special departments, passengers or personnel entering need to pass through the security inspection channel equipped with special inspection instruments. At the same time, in order to ensure the effect of security inspection, or to facilitate the automatic statistics and counting of passing personnel, a special anti-tailgating passage is usually set up in front of the security inspection passage. The entrance and exit of the long and narrow channel space are respectively provided with a do...

[0002] In some special industries such as roads, railways, and air passenger transport, in order to ensure the safety of vehicles, or in some special departments, passengers or personnel entering need to pass through the security inspection channel equipped with special inspection instruments. At the same time, in order to ensure the effect of security inspection, or to facilitate the automatic statistics and counting of passing personnel, a special anti-tailgating passage is usually set up in front of the security inspection passage. The entrance and exit of the long and narrow channel space are respectively provided with a door (or bar) to prevent people from passing. The door at the entrance and exit of the anti-tailgating channel is usually in a normally closed state. When the entrance of the passage is going to pass through the anti-tailgating passage, the door at the entrance of the anti-tailgating passage is opened first, and after the passers-by alone or with luggage pass through the entrance of the anti-tailgating passage and completely enter the anti-tailgating passage, the door at the entrance is closed, and the passers-by Through the channel space of the anti-tailgating channel, the infrared probes set in the channel space sense and generate induction signals.
