Embodiment Construction

[0057] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0058] The present application provides a method for reducing false triggering of multi-channel gates, which utilizes the difference in target image frames of the same target collected by an image recognition device to trigger the correct channel.

[0059] see figure 2 as shown, figure 2 It is a schematic flowchart of a method for reducing false triggering of multi-channel gates according to an embodiment of the present application. Including the following steps:

[0060] Step 201, receiving the target image frame from the image recognition device of each channel,

[0061] Step 202, when the same target exists in each target image frame, calculate the offset of the target in each target image frame relative to the center of the target image frame, and / or th...

Abstract

The invention discloses a method for reducing false triggering of a multi-channel gate; the method comprises the steps: receiving a target image frame from an image recognition device of each channel, calculating the offset of a target in each target image frame relative to the center of the target image frame, and / or the ratio of a target image when the same target exists in each target image frame, and comparing the offset of each target image frame and / or the target picture ratio, and taking the channel corresponding to the target image frame with the minimum offset and / or the maximum target picture ratio as a correct channel for triggering. According to the method for reducing false triggering of the multi-channel gate machine, man-machine interaction is not needed, the installation mode of the gate machine does not need to be modified, the method has wide adaptability to application scenes, and the safety of the gate machine and the user experience are improved under the condition that the passing efficiency is not affected.

Description

technical field [0001] The invention relates to the field of access control, in particular to a method for reducing false triggering of multi-channel turnstiles. Background technique [0002] The channel gate is a channel blocking device (channel management equipment), which is mainly used in urban rail transit, scenic spots, residential areas and other scenarios to manage the flow of people and regulate the entry and exit of pedestrians. Its basic core function is to realize the passage of only one person at a time, and it can be used in the entrance and exit channels of various charging and access control occasions. [0003] Existing gates are usually equipped with an image recognition device for a single channel, which is responsible for the authority authentication function of the channel. When the target enters the identification area, the image recognition device starts to work immediately, and the channel is opened after the authority authentication is passed. In com...
