Embodiment Construction

[0014] see figure 1 and figure 2 , figure 1 is a schematic diagram of the temperature sensing device 10 of the present invention, figure 2 for use figure 2 The schematic diagram of the temperature sensing device 10 sensing the surface temperature image of the target object is shown. The temperature sensing device 10 of the present invention includes an image capture unit 20 , an image processing unit 30 , an image database 40 and a comparison unit 50 . The temperature sensing device 10 is used for sensing whether an image area whose surface temperature exceeds a predetermined value in a surface temperature image 12 of a target object is an important area. In this embodiment, the target object is a person's head. see figure 1 and figure 2 . The image capturing unit 20 utilizes an infrared image sensing technology to capture the surface temperature image 12 of the target object. exist figure 2 In the example shown, the surface temperature image 12 of the target ob...

Abstract

This invention provides a temp sensing device for sensing if the region with a mark object temp surpassing a preset value is a major region. The device includes an image pick up unit, an image database and a comparing unit, among which the image pick up unit is for extracting a surface temperature image of the mark object, the image process unit is for labeling the region with the temperature of the surface temperature image surpassing the preset valure with a preset method. The image database stores multiple surface major region images for defining the major regions of the surface temp images, the comparing unit carries out an image discriminating technology.

Description

technical field [0001] The present invention relates to a temperature sensing device (Temperature Sensor), in particular to a temperature sensing device capable of automatically sensing whether an area where the temperature of a target object exceeds a predetermined value is a critical area. Background technique [0002] Existing temperature sensing devices for sensing human body temperature are various, such as various mercury thermometers, thermistor thermometers, liquid crystal thermometers and infrared sensing thermometers. These thermometers are the most convenient to use with infrared sensing thermometers, and generally do not need to touch the body of the measured object during use. According to the difference in the performance of different infrared sensing thermometers, the temperature measurement results of the part or the whole of the object under test can be obtained within a few seconds by only a few centimeters to several meters a...
