Ticket-checking monitoring method

Abstract

The invention provides a ticket-checking monitoring method. A side projection width upper-limit value of the knee parts of a person is calculated according to the more easily obtained front head image and side projection of a person checking tickets, the width of the knee parts of the person is cut out from the side projection, and comparison is performed. A gate is controlled to be in an open state if the width, cut out from the projection width, of the knee parts of the person is smaller than the calculated side projection width upper-limit value of the knee parts of the person; the difference value between the width, cut out from the projection width, of the knee parts of the person and the calculated side projection width upper-limit value of the knee parts of the person is further judged if the width, cut out from the projection width, of the knee parts of the person is greater than the calculated side projection width upper-limit value of the knee parts of the person; if the difference value between the width, cut out from the projection width, of the knee parts of the person and the calculated side projection width upper-limit value of the knee parts of the person is greater than a preset threshold value M, it is indicated that two persons pass through the gate in a close proximity mode, the gate is in a closed state at the moment and can perform automatic and accurate identification, prevent the two persons from passing through the gate in the close proximity mode and prevent fare evasion.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a ticket checking monitoring method. Background technique [0002] In rail transit or high-speed rail stations, ticket gates are usually used to check tickets. Existing ticket gates are usually equipped with sensors to sense passing signals of passengers. When only one ticket is checked but two consecutive passengers pass, The sensor will receive two passing signals, at this time, the gate can recognize that someone has escaped, and then send an alarm or close the gate to prevent fare evasion. However, if two people pass through the gate closely next to each other, the sensor will not be able to sense the two signals, and thus will not be able to send an alarm to stop fare evasion. Next to the method of passing through the gates and the automatic ticket checking device. Contents of the invention [0003] Therefore, the technical problem to be solved by the present in...

Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the automatic ticket checking device and method in the prior art cannot accurately prevent fare evasion, especially the defect that two people cannot pass through the gate next to each other, so as to provide a more accurate Deterring fare evasion, especially to prevent two people passing through the gate close to each other
