Body temperature detection method, system and device and thermal infrared image processor

Abstract

The invention discloses a body temperature detection method and device and a thermal infrared image processor. The method comprises the steps of detecting the body surface temperature of a preset partof a target object; determining the body temperature of the target object according to the detected body surface temperature; determining whether the body temperature of the target object is abnormalor not according to the body temperature of the target object and a temperature threshold value, wherein the temperature threshold value is determined through the following operations that a body temperature information set, detected within a previous preset time range, of a historical detection object is obtained; and the temperature threshold is determined according to the body temperature information in the body temperature information set. And the temperature threshold value can be dynamically updated and adjusted continuously according to the change of the environment temperature. In this way, in the process of determining whether the body temperature of the target object is abnormal or not according to the temperature threshold value, individuals who have the body surface temperature lower than the conventional fever temperature but are actually in the fever state can be timely and accurately checked out, and the possibility of large-range infection is greatly reduced.

Description

technical field [0001] The present application relates to the technical field of human body temperature detection, in particular to a body temperature detection method, system, device and thermal infrared image processor. Background technique [0002] With the increasing demand for temperature monitoring of target objects (such as human body) in designated scenes, many temperature measurement systems have appeared on the market for users to use. Most of the current temperature measurement systems detect human body temperature based on thermal infrared images, and judge whether the body temperature of the target object is abnormal according to the detected human body temperature and the preset temperature threshold. However, the detection of human body temperature based on thermal infrared images is easily affected by the ambient temperature. For example, due to the cold outside in the north, the human body surface temperature is greatly affected by the environment and is u...

Problems solved by technology

[0004] The present disclosure provides a body temperature detection method, system, device, and thermal infrared image processor to at least solve the problem existing in the prior art that human body temperature detection based on thermal infrared images is easily affected by the ambient temperature, making people in a state of fever The body surface temperature detected by the human body is still lower than the preset fever temperature, so it is impossible to timely and accurately check the fever individual, which is likely to cause technical problems of large-scale infection
