Temperature measuring method, device and system

Abstract

The embodiment of the invention discloses a temperature measurement method, device and system, and belongs to the field of computer vision research. The method comprises the steps that a first visible light image and a first thermal infrared image are acquired, target object detection processing is carried out on the first visible light image, first position information is obtained, and the first position information is used for indicating the position of a target object in the first visible light image; and performing image interception processing on the first visible light image and the first thermal infrared image based on the first position information to obtain a local image, inputting the first position information and the local image into a parallax estimation network model to obtain a target binocular parallax, determining second position information according to the first position information and the target binocular parallax, and outputting the second position information. And determining the temperature of the target object from the first thermal infrared image according to the second position information. Thus, according to the target binocular parallax and the first position information, the position of the target object can be determined in the first thermal infrared image, and then the temperature of the target object is determined.

Description

technical field [0001] The embodiments of the present application relate to the field of computer vision research, and in particular to a temperature measurement method, device and system. Background technique [0002] Public places with a large flow of people, such as stations, airports, hospitals, ports, and schools, often require temperature measurement to find out people with fever, especially in the case of an epidemic. Temperature measurement is even more important. [0003] Usually, temperature measurement in public places generally adopts non-contact temperature measurement methods. Commonly used temperature measurement systems include handheld temperature measurement guns and uncooled infrared temperature measurement systems. Since the handheld temperature measurement gun can only measure a single person at a time, And it often happens that each person needs to take repeated measurements to complete the temperature measurement, which is inefficient and less accurate...

Problems solved by technology

[0004] However, using thermal infrared images to locate the position of the target may cause the target object to be mixed with the background and other objects due to the low original resolution of the thermal infrared image and easy loss of texture details. The target object is identified, and then the temperature of the target object cannot be determined, resulting in temperature measurement failure
