In other words, the thermal imaging camera 110 included in the thermal imaging distal care system 100 of the present invention is disposed above the patient 200 and captures the thermal image 111 of the upper body region of the patient 200, thereby corresponding to the upper body region of the patient 200. The thermal image 111 has temperature information such as a temperature distribution of the upper body region, and the above-described setting of the infrared camera 110 above the patient 200 is only a preferred example of the present invention, and should not be set as the position of the infrared camera 110. limited.

The image processing module 120 is connected (or electrically connected) to the infrared camera 110, and receives the thermal image 111 captured by the infrared camera 110 from the upper body region of the patient 200, and is applied to the thermal image 111 in a time interval. The temperature of each point coordinate in the specific dot area is subjected to rolling average to generate the area rolling average temperature 121.

The analysis module 130 connects (or electrically connects) the image processing module 120 and presets a fever temperature, and the analysis module 130 receives the area rolling average temperature 121 corresponding to the thermal image 111 by the image processing module 120, and compares the fever accordingly.

Fig. 5 is a temperature graph of coordinate pixels of the thermal imaging type distal care system of the present invention; Fig. 6 is a schematic view of a region of interest of the thermal imaging type distal care system of the present invention. As shown, the image processing module 120 can treat the upper body region of the patient 200 as the entire spatial region of interest (SROI _T ) and divide into a plurality of pixel regions in a two-dimensional distribution, for example, The entire thermal image 111 can be divided into L _N x M _N pixel regions by the X axis and the Y axis, and can be analyzed for a specific region (the region of L _i x M _i pixels in the figure); The pixel may have corresponding temperature information and its position coordinate (x ₀ , y ₀ ). The parameters in Figure 3 are defined as follows: L _N x M _N : The complete detection activity area of the L _N line and the M _N column.

L _i x M _j (0<L _i <L _N , 0<M _j <M _N ): A subset of the Li row and the Mj column in the active region is completely detected.

(x ₀ , y ₀ ) pixels: pixels located at coordinates (x ₀ , y ₀ ).

The parameters in Figure 4 are defined as follows: STmax: The maximum temperature in the space between the selected L _i x M _j pixels in a specific time.

STmin: The lowest temperature in the space between the selected L _i x M _j pixels at a particular time.

The region of interest SROI _T mentioned above preferably should include the head of the patient; at the same time, in order to reduce the burden on the system and determine the location of the human body, the analysis module 130 can define the temperature in the predetermined temperature range from the region of interest SROI _T The inner region is the critical region of interest (SROI _C ); and the region with severe temperature change in the critical region of interest SROI _C is defined as the variable region SROI _F (Fluctuate spatial region of interest). The parameters in Figure 6 are defined as follows: SROI _T : The entire area of interest is selected for monitoring by system settings.

SROI _C : A key area of interest that is selected by a particular standard, such as an area above 37 ° C, and may be continuous or discontinuous.

SROI _F : The variable area, which is one of the key areas, whose temperature fluctuation rate is faster than the preset volatility.

Specifically, the TROI in FIG. 5 is an interest time region; t _T is the total time of the TROI; Δt _p is the time interval of each measurement; and the pixel temperature Temp _{pixel of} each _pixel can be expressed as: Where t is time, k is a positive integer greater than 0, n is the time interval Δt _p of the sampling, the total number of detected temperatures, Temp _k (t) is located at the corresponding pixel position (x _i , y _j ) , the detected temperature.

However, according to the pixel temperature Temp _pixel definition, the region rolling average temperature (Temparea) 121 generated by the temperature detection for the specific dot region L _S × M _S can be expressed as Where i, j, k are positive integers greater than 0, L _S ≦ L _N , M _S ≦ M _N , and when L _S = M _S =1, Temp _area = Temp _pixel . In this way, the user can adjust the size of the individual pixels according to the resolution of the thermal image, the number of detections per unit time of the infrared camera and the processing power of the system, so as to further reduce the use of system resources and the burden on the system, and Improve system processing speed.

Wherein, the high temperature point temperature is set to be equal to or higher than the maximum allowable human skin temperature in the room temperature room, for example, 42 °C.

In other words, if the area rolling average temperature 121 is higher than the fever temperature but lower than the high temperature point temperature, the analysis module 130 calculates the area rolling average temperature 121 is higher than the fever temperature and lower than the high temperature point temperature in the preset time period. The number of statistics; further, when the statistical number counted by the analysis module 130 is greater than the preset number of times in the preset time period, it indicates that the patient 200 continues to maintain the body above the fever temperature. The analysis module will generate a confirmation fever alarm 104 to the remote care station 300 to notify the relevant medical staff (such as a caregiver) to go to the location of the patient 200 (such as a ward) for processing, or to record for subsequent reference.
