Multispectrum-based person movement track determination method

Abstract

The invention provides a multispectrum-based person movement track determination method. The method comprises the following steps: obtaining an infrared image of a to-be-identified person through an infrared camera; determining a body temperature value of the to-be-recognized person according to the infrared image, and when the body temperature value is greater than a preset temperature value, obtaining a face image of the to-be-recognized person based on a visible light camera; identifying identity information of the to-be-identified person through the face image; and determining a movement track of the to-be-recognized person based on the identity information. An infrared image of a person entering the field of view of the camera can be quickly captured through the infrared camera, and the person with abnormal body temperature can be accurately determined after image denoising processing. Meanwhile, for a person with abnormal body temperature, the identity and the movement track of the person are determined through the face recognition technology, so that response is made quickly, and further expansion of the epidemic situation range is avoided.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a multispectral-based method for determining a person's action trajectory. Background technique [0002] With the spread of the epidemic around the world, it is imperative to measure the body temperature of people entering public places. However, due to the high flow of people in public places during certain periods of time, such as subway peak hours, supermarket entrances, office building peak hours, etc., temperature checks are performed one by one for entering personnel, which will inevitably affect the normal order of various places. In addition, it is also very necessary to accurately identify the person who detects abnormal temperature and determine their action trajectory. At present, there is no technical method that can efficiently solve the above technical problems. Contents of the invention [0003] The object of the present invention is to provide ...

Problems solved by technology

However, due to the high flow of people in public places during certain periods of time, such as subway peak hours, supermarket entrances, office building peak hours, etc., temperature checks are carried out on the people who enter one by one, which will inevitably affect the normal order of each place.

In addition, it is also very necessary to accurately identify the person who detects abnormal temperature and determine their trajectory. At present, there is no technical means that can efficiently solve the above technical problems
