Automatic ticket checking device for performing passage detection based on depth image

Abstract

The invention relates to an automatic ticket checking device which can be arranged at track traffic stations, docks, tourist attractions and the like. A depth image video camera 30 is used for shooting a depth image of a scene of a ticket checking channel 20 of the automatic ticket checking device, and a passer detection unit can judge and track the positions of passers and objects in the ticket checking channel according to the depth image. A master control unit is used for controlling a ticket checking port door 13 to open and close at appropriate time according to the positions of the passers and tracking information which are judged by the passer detection unit. Therefore, the invention provides the automatic ticket checking device which can accurately track the positions of the passers, eliminate error detection or error judgment and realize high reliability.

Description

Technical field [0001] The invention relates to an automatic ticket checking system, and relates to an automatic ticket checking device installed at a rail transit station. Background technique [0002] A variety of automatic ticket checking devices are currently installed in rail transit stations. These automatic ticket checking devices can accept magnetic tickets and RFID tickets, read the recorded information stored in the ticket, and determine whether to allow passers with the ticket to pass through the automatic ticket checking device. If the automatic ticket checking device determines that the passer is not allowed to pass, the pass control device installed on the automatic ticket checking device is in a closed state to prevent the passer from passing. Usually the passage control device is a door device that can automatically open and close. [0003] If the automatic ticket checking device determines that the passer is allowed to pass, the pass control device installed on t...

Problems solved by technology

[0005] Chinese patent 01108925.3 discloses an automatic ticket checking device. The automatic ticket checking device is arranged along a channel with a minimum length, and senses the passers-by traveling along the ticket checking channel through several groups of sensors distributed on the side of the channel. Due to the simple form of the sensor, it cannot Effectively perceive passers-by and accessory luggage, etc., and there are false detections and false judgments

These systems have not solved the problem that the reliability is not high enough, and the volume of the device cannot be reduced due to the limitation of the number of sensors and the distribution interval.
