Embodiment Construction

[0017] Please refer to figure 1 , which shows a schematic block diagram of a thermal imager with a function of temperature compensation for distance according to a preferred embodiment of the present invention.

[0018] As shown in the figure, the thermal imager with the function of temperature compensation to the distance of the present invention includes: a matrix type distance sensor 10; a matrix type far infrared sensor 20; a control unit 30; and a combination of a display device 40 made.

[0019] Wherein, the matrix distance sensor 10 is composed of a plurality of distance sensors for sensing the distance information of an object 100 to be measured. Wherein, the matrix distance sensor 10 is, for example but not limited to, a matrix optical sensor. Wherein, the object to be tested 100 is for example but not limited thereto.

[0020] The matrix far-infrared sensor 20 is composed of a plurality of far-infrared band sensors capable of detecting object radiation, and is use...

Abstract

The present invention provides a thermal imager with a function of temperature compensation for distance, comprising: a matrix type distance sensor for sensing distance information of an object to be measured; a matrix type far-infrared sensor for sensing the distance information of an object to be measured far-infrared radiation information of the object to be measured; a control unit, respectively coupled to the matrix-type distance sensor and the matrix-type far-infrared sensor, has a temperature compensation table, which can compensate the temperature according to the distance information and the far-infrared radiation information The table looks up the table to obtain an uncompensated temperature value and a compensated correct temperature value; and a display device coupled to the control unit for displaying the compensated correct temperature value of the object to be measured. In addition, the present invention also provides a method for temperature compensation of the thermal imager.

Description

technical field [0001] The present invention relates to a thermal imager with the function of temperature compensation for distance and its temperature compensation method, especially to a temperature compensation table that can be looked up according to distance information and far-infrared radiation information to obtain a temperature compensation value. A thermal imager with a function of temperature compensation for distance and a temperature compensation method for compensating the temperature of the object to be measured according to the temperature compensation value. Background technique [0002] Nowadays, it is more and more popular to use infrared thermal imaging to sense the temperature of the target object. For example, airports, public places or government agencies, etc., all use infrared thermal imaging cameras to sense the body temperature of passengers or tourists to avoid body temperature Abnormal passengers or tourists enter the country to improve the effec...
