Problems solved by technology

[0003] However, these methods are time-consuming, laborious, and inefficient, especially in scenes with a large flow of people, and it is easy to miss the target when the observer is tired.
For the use of image recognition technology to identify pedestrians wearing masks, it is easily affected by the external lighting environment and has low reliability.

Embodiment 1

[0032] see figure 1 , figure 1 It is a schematic flow chart of a high-precision mask-wearing identification method disclosed in the embodiment of the present invention. in, figure 1 The described method can be applied to a public place monitoring system, and the public place monitoring system includes a plurality of cameras and an algorithm server, and other monitoring systems also belong to the protection scope of the present invention, and the embodiments of the present invention are not limited. Such as figure 1 As shown, the high-precision mask wearing recognition method may include the following operations:

[0033] Step S101: Obtain video stream data through multiple cameras.

[0034] In this application, the camera device in a common public place can be directly used to collect video stream data through the camera device. Therefore, there is no need to install additional outdoor equipment, which greatly reduces the time and material costs required for supporting equ...

Embodiment 2

[0048] see figure 2 , figure 2 It is a schematic flow chart of another high-precision mask wearing identification method disclosed in the embodiment of the present invention. in, figure 2 The described method can be applied to a public place monitoring system, and the public place monitoring system includes a plurality of cameras and an algorithm server, and other monitoring systems also belong to the protection scope of the present invention, and the embodiments of the present invention are not limited. Such as figure 2 As shown, the high-precision mask wearing recognition method may include the following operations:

[0049] Step S201: Obtain video stream data through multiple cameras.

[0050] In this application, the camera device in a common public place can be directly used to collect video stream data through the camera device. Therefore, there is no need to install additional outdoor equipment, which greatly reduces the time and material costs required for supp...

Embodiment 3

[0067] see image 3 , image 3 Described is a high-precision wearing mask recognition system, and the system includes:

[0068] A plurality of cameras 1 acquire video stream data.

[0069] The algorithm server 2 is used to extract feature data according to the video stream data.

[0070] The calculation module 3 is used to input the characteristic data into the constructed mask recognition model to perform confidence calculation and generate a confidence value.

[0071] Judgment module 4 is used to judge whether the feature data wears a mask according to the preset confidence threshold and confidence value, if the confidence value is greater than the preset confidence value, then it is judged that the feature data does not wear a mask, and an alarm message is output.

[0072] The decoding module 5 is used to carry out the image decoding operation to the video stream data, and generates the image data in the RGB format and transmits it to the algorithm server 2.

Abstract

The invention discloses a high-precision mask wearing identification method and system, the method is applied to a public place monitoring system, the public place monitoring system comprises a plurality of cameras and an algorithm server, and the method comprises the following steps: obtaining video stream data through the plurality of cameras; extracting feature data according to the video stream data; inputting the feature data into a constructed mask recognition model for confidence calculation, and generating a confidence value; and judging whether the feature data wears the mask or not according to a preset confidence threshold value and the confidence value, if the confidence value is greater than the preset confidence value, judging that the feature data does not wear the mask, andgenerating alarm information to be output. Therefore, the pedestrian position can be more accurately positioned through the deep learning technology, the reliability and anti-interference performanceof identification are greatly improved, manpower and material resources are saved, and the improvement of the labor efficiency is facilitated.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a high-precision mask-wearing recognition method and system. Background technique [0002] At present, whether people entering and exiting wear masks is more subjectively judged by manual on-site observation, observing multiple scenes in the monitoring room, and using simple image recognition technology to assist the monitoring of staff. [0003] However, these methods are time-consuming, labor-intensive, and inefficient, especially in scenes with a large flow of people, and it is easy to miss the target when the observer is tired. For the use of image recognition technology to identify pedestrians wearing masks, it is easily affected by the external lighting environment, and the reliability is low. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a high-precision mask wearing recognition method and system, ...
