Embodiment 1

[0054] This embodiment provides a monitoring method, including the following steps:

[0055] S1: Obtain the frontal head image of the person checking the ticket at the gate entrance;

[0056] S2: Calculate the upper limit of the lateral projection width of the human buttocks according to the obtained frontal head image;

[0057]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;

[0058] S4: Intercept the width of the human hip from the side projection;

[0059] S5: Comparing the width of the person's buttocks intercepted from the side projection with the calculated upper limit value of the side projection width of the person's buttocks;

[0060] If the width of the person's buttocks intercepted from the projection width is less than the calculated upper limit value of the side projection width of the person's buttocks, then the control gate is in the open state;

[0061] If the width of ...

Embodiment 2

[0088] This embodiment provides a monitoring method, which is a modification on the basis of Embodiment 1, and includes the following steps:

[0089] The difference between this embodiment and embodiment 1 is that

[0090] 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;

[0091] So that the side projections are all infrared images.

[0092] 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 objects and clothes carried is not much different from the room temperature, so it can be more accurately viewed from the side. The actual width of the human body is recognized in the projection.

[0093] In addition, in the conversion formula, since the infrared image obtained by t...

Embodiment 3

[0095] This embodiment provides a monitoring method, which is a modification on the basis of Embodiment 1. The method uses a monitoring device, and the monitoring device includes, for example figure 1 as shown,

[0096] Gate 1, which has a gate and a ticket inspection channel that is opened or closed under the control of the gate;

[0097] 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;

[0098] Camera 2, for taking frontal head images;

[0099] The alarm device is used to issue a fare evasion alarm signal;

[0100] Processor 3 receives the frontal head image captured by the camera, and calculates the upper limit of the width of the person's side projection according to the obtained frontal head image, and then calculates the width of the person's buttocks intercepted from the side projection. Obtain the upper limit value of the lateral projection width of the human buttocks for c...

Abstract

The video monitoring method provided by the present invention calculates the upper limit of the side projection width of the human buttocks through the easily obtained frontal head image and side projection of the person who is checking the ticket, and then calculates the upper limit value of the side projection width of the person's buttocks through the obtained frontal head image. Only the projection width If the width of the buttocks of the intercepted person is greater than the calculated upper limit of the lateral projection width of the buttocks of the person, it means that there are two people passing through the gate next to each other, which can automatically and accurately identify and prevent two people from passing through the gate next to each other. Prevent fare evasion. In addition, the buttocks are the widest part of the 0.50-0.75H from the ground. Since this height range is defined as the buttocks, gender differences between men and women can be taken into account, thereby achieving better monitoring accuracy.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video monitoring method 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...
