Embodiment 1

[0057] This embodiment provides a video surveillance method for preventing fare evasion, including the following steps:

[0058] S1: Obtain the frontal head image of the person checking the ticket at the gate entrance;

[0059] S2: Calculate the upper limit of the lateral projection width of the chest and knees of the person according to the obtained frontal head image;

[0060] S3: Use the ordinary width sensor on the gate to obtain the side projection of the person checking the ticket at the entrance of the gate;

[0061] S4: Intercept the width of the human chest and knees from the side projection;

[0062] S5: Comparing the widths of the chest and knees of the person intercepted from the side projection with the calculated upper limit values ​​of the widths of the side projections of the hips, chest and knees of the person;

[0063] If at least one of the widths of the chest and knees of the person intercepted from the projection width is smaller than the calculated uppe...

Embodiment 2

[0094] This embodiment provides a video surveillance method for preventing fare evasion, which is a modification based on Embodiment 1 and includes the following steps:

[0095] The difference between this embodiment and embodiment 1 is that

[0096] In step S3, the infrared sensor on the gate is used to acquire the side projection of the infrared image of the person who is checking the ticket at the entrance of the gate;

[0097] Make the side projections are all infrared images;

[0098] If the widths of the person's buttocks, chest and knees intercepted from the projection width are all greater than the calculated upper limit of the side projection width of the person's chest and knees, then the control gate is in the closed state.

[0099] Because the side projection of the person who is checking the ticket is obtained by the infrared sensor, the infrared image is obtained. The human body of the person who is checking the ticket will emit heat, and the temperature of the ...

Embodiment 3

[0102] The present embodiment provides that the present invention also provides an anti-fare evasion video monitoring device, comprising

[0103] Gate 1, which has a gate and a ticket inspection channel that is opened or closed under the control of the gate;

[0104] The width sensor is arranged on the gate 1, and is used to obtain the side projection width of people and / or objects to pass through the gate;

[0105] Camera 2, for taking frontal head images;

[0106] The alarm device is used to issue a fare evasion alarm signal;

[0107] Processor 3 receives the frontal head image taken by the camera, calculates the upper limit of the width of the side projection of the person according to the obtained frontal head image, and then takes the chest and knees of the person intercepted from the side projection The width is compared with the calculated upper limit of the side projection width of the chest and knees of the person; and the opening or closing of the gate and the alar...

Abstract

The invention provides a fare evasion preventing method and a fare evasion preventing device. The fare evasion preventing method comprises the steps of acquiring a front head image and a side projection of a person in fare evasion; calculating a side projection width upper limit values of the chest part and knee part of the person through the acquired front head image; acquiring the widths of the chest part and the knee part of the person from the side projection; comparing the side projection width upper limit values of the chest and knee of the person with the widths of the chest part and the knee part; and when the acquired widths of the chest part and the knee part of the person are larger than the calculated side projection width upper limit values of the chest part and the knee part of the person, determining a fact that two close persons pass through a brake machine. The fare evasion preventing method and the fare evasion preventing device can identify and prevent the fact that two close persons pass through the brake machine.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a method and device for preventing fare evasion. 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 ...
