Embodiment Construction

[0018] like figure 1 , figure 2 As shown, a scanning method for measuring the radiation temperature of the human body surface includes a process of collecting the distribution of the radiation temperature of the human body surface by using an infrared thermal imaging detector, which is characterized in that: Body surface radiation temperature distribution In the process of generating the human body surface radiation temperature distribution image, an infrared thermal imaging detector 1 is placed in a plane, and in a state of being stationary relative to the measured object, using the infrared thermal imaging The detector collects the first image of the radiation temperature distribution on the human body surface, and then translates or vertically moves the infrared thermal imaging detector in the plane, and the entire distance of the translation or vertical movement is equal to or close to the first image of the human body surface radiation The width or height of the tempera...

Abstract

Provided is a scanning method for measuring the radiation temperature of a human body surface. An infrared thermal imaging detector is used to perform one-by-one pixel translation or vertical movementwith respect to a measured object, human body surface radiation temperature distribution images are collected continuously, the radiation temperature of a pixel corresponding to any fixed point in the measured object is extracted one by one from all the collected human body surface radiation temperature distribution images according to the movement direction, the adding cumulative calculation isperformed to obtain the average radiation temperature of any fixed point of the measured object and the average radiation temperature is taken as a credible temperature, finally the credible temperature values of all the fixed points of the measured object form a credible infrared thermal imaging temperature distribution image of the human body surface through image reproduction software accordingto original coordinates. A device for implementing the method includes the infrared thermal imaging detector, a two-axis moving mechanism, a moving mechanism control system and a computer. Accordingto the method and device, the influence caused by dead pixels of the infrared thermal imaging detector is solved, and measured data is more accurate.

Description

technical field [0001] The invention relates to the field of physics, in particular to temperature measurement technology, in particular to a scanning method and device for measuring the radiation temperature of the human body surface. Background technique [0002] Medical infrared functional imaging equipment is widely used in medical treatment. It adopts the method of whole-frame shooting to record the body surface radiation temperature hot spots of the human body. The matrix point pixels of each detector correspond to a body surface temperature hot spot of a certain part of the human body. However, in the prior art, pixels of infrared thermal imaging detectors often have dead pixels. Therefore, before the detector leaves the factory, the manufacturer will do some processing to shield the dead pixel. In medical applications, the body surface radiation temperature hotspot data corresponding to the dead pixel pixel is not true, which will cause misjudgment and error. Cont...
