[0058] Compared with the first embodiment, the second embodiment has a video monitor 8 and a memory 9 added, and the camera face recognition head tracking unit 1 has the function of storing the images of the subject captured by the camera.

[0059] Specifically, on the basis of the first embodiment, the CPU 2 instructs the camera face recognition head tracking unit 1 to capture images of subjects whose temperature exceeds the threshold. The camera face recognition head tracking unit 1 stores the image of the subject whose temperature exceeds the threshold captured by the camera not shown in the memory 9, so as to further deploy and control through the image of the subject.

[0060] In addition, the CPU2 controls the camera face recognition head tracking unit 1 to output the video signal including the image of the subject and its temperature to the optional video monitor 8 for display.

[0061] Those skilled in the art will understand that the above-mentioned video monitor 8 ma...

[0066] Compared with the first embodiment and the second embodiment, the third embodiment of the present invention does not have the fast mechanical servo 4, and other constitutions are the same as those of the first embodiment or the second embodiment.

[0067] The operation of the third embodiment will be described below.

[0068] In the third embodiment, the infrared thermometer 5 does not move, but only monitors a temperature measurement control line (when using a point thermometer) or controls a control column (such as using a surface infrared thermal image). instrument). And the subject enters the control range according to the predetermined straight line drawn. And when the forehead above the eyes of the subject touches the temperature measurement control line or the control column, the infrared thermometer 5 detects the temperature of the forehead at this moment.

[0069] The camera face recognition head tracking unit 1 calculates the distance from the forehead when ...

[0073] Compared with the third embodiment, the fourth embodiment is applicable to the case of performing high-precision measurement and detection. The functions of the CPU unit of the fourth embodiment are different from those of the third embodiment.

[0074] In the fourth embodiment, the infrared thermometer 5 does not move, but only monitors a temperature measurement control line (when using a point-type thermometer) or controls a control column (such as using a surface infrared thermal image). instrument). And the subject enters the control range according to the predetermined straight line drawn.

[0075] Due to the high precision measurement, the person also has to move the head slightly to precisely align the position. At this time, the camera face recognition head tracking unit 1 provides parameters such as the distance and center deviation from the forehead position above the eyes of the subject to the infrared thermometer 5 and the center deviation, and provides th...

Abstract

Temperature measuring equipment and method thereof are disclosed, wherein the positions of privileged sites of a target to be measured are positioned; the thermo-detector is moved to aim at the positions of the determined privileged sites mentioned above; measuring the temperature of said privileged sites; correcting the measured temperature by the thermo-detector, according to the position relation between the target to be measured and the thermo-detector. The present invention can obtain positioning information of accurate sites, with improved temperature measurement accuracy.

Description

technical field [0001] The invention relates to a temperature measuring method and a temperature measuring device, in particular to a temperature measuring method and a temperature measuring device capable of automatic positioning and correction of measured temperature. Background technique [0002] Currently, there are two types of known temperature measurement technologies: contact temperature measurement technology and non-contact temperature measurement technology. Whether it is contact temperature measurement technology or non-contact temperature measurement technology, if the temperature is measured accurately, human intervention is required to locate the temperature measurement site. For activity targets such as people who do not strictly restrict their physical activities, it is difficult to accurately locate the temperature measurement site. [0003] For non-contact temperature measurement technology such as infrared temperature measurement technology, factors such...
