Human body infrared thermal image processing method and system

Abstract

The invention relates to a human body infrared thermal image processing method and system. The processing method includes the steps of obtaining a minimum temperature Tmin and a maximum temperature Tmax of a human body based on a human body temperature profile; identifying a region with the temperature in a range from Tmin to Tmin+t1 as a first region and a region with the temperature in a range from Tmax-t2 to Tmax as a second region, where t1 is a first preset value, t2 is a second preset value, and Tmin+t1 is less than Tmax-t2; and taking the first region as a low temperature region to be filled with a low temperature color, and taking the second region as a high temperature region to be filled with a high temperature color, the low temperature color being different from the high temperature color. By implementing the invention, the low temperature region and the high temperature region of an infrared thermal image of the human body can be clearly displayed at the same time, withoutcumbersome operations of a user in the past, that is, to first shift the window of the infrared thermal image of the human body toward the low temperature region to obtain a first region image and then shift to the high temperature region to obtain a second region image, with the low temperature region and the high temperature region being unable to be displayed at the same time.

Description

【Technical field】 [0001] The invention relates to image processing, in particular to a processing method and a processing system for infrared thermal images of a human body. 【Background technique】 [0002] In the existing human body infrared thermal image processing process, the system will combine the color allocation scheme to attach colors to the corresponding temperature regions in the human body infrared thermal image, so that human eyes can see it. In the existing color distribution scheme, bright colors such as red are usually used to indicate high temperature, dark colors such as blue are used to indicate low temperature, and there is a gradient between adjacent temperatures. [0003] The disadvantage of the prior art is that, as figure 1 As shown, after the default color distribution scheme is applied to the infrared thermal image of the human body, since the color distribution scheme is a gradual pseudo-color, the performance of the high temperature area and the l...
