Hereinafter, a thermal image overlay monitoring apparatus according to an embodiment of the present invention will be described with reference to FIG. 1, with reference to FIGS. 2 to 11. FIG.

1, the thermal image overlay monitoring apparatus includes a first infrared ray detecting sensor unit 10, a second infrared ray sensor unit 20, a camera unit 30, a data processing unit 40, and a monitor unit 50 .

The first infrared detection sensor unit 10 and the second infrared detection sensor unit 20 respectively detect the infrared radiation energy generated in the subject. For example, the first infrared detection sensor unit 10 and the second infrared detection sensor unit 20 detect energy by a device sensitive to infrared radiation energy, It can be converted into an electric signal through calculation.

In particular, as shown in FIGS. 2 and 3, the first infrared detection sensor unit 10 and the second infrared detection sensor unit 20 include a pair of sensor types ≪ / RTI > At this time, the first infrared detection sensor unit 10 and the second infrared detection sensor unit 20 may be arranged so that the infrared detection regions overlap each other. That is, the directing directions of the first infrared detecting sensor unit 10 and the second infrared detecting sensor unit 20 can be set so that the infrared detecting areas overlap each other.

For example, as shown in FIG. 4, the first infrared detection sensor unit 10 and the second infrared detection sensor unit 20 may be arranged so that a part of the infrared detection area overlaps with each other. 5, each of the first infrared sensor portion 10 and the second infrared sensor portion 20 may have a horizontal and vertical viewing angle of 60 degrees * 15 degrees, and the first infrared sensor portion The infrared detection area of the first infrared sensor 10 and the second infrared sensor 20 may be an area corresponding to a viewing angle of 60 degrees * 30 degrees.

Accordingly, the thermal imaging overlay monitoring apparatus according to the embodiment of the present invention uses a pair of infrared ray detection sensors in which the infrared ray detection regions overlap each other, and determines which portion of the object and its surrounding objects has a higher or lower temperature It is possible to obtain a thermal image overlay image which can be accurately grasped.

The camera unit 30 acquires an actual image in a direction that the first infrared detection sensor unit 10 and the second infrared detection sensor unit 20 are oriented. For example, the viewing angle of the camera unit 30 may be greater than the viewing angle of the first infrared ray sensor unit 10 and the second infrared ray sensor unit 20, The image may include an infrared detection area by the first infrared detection sensor unit 10 and the second infrared detection sensor unit 20. [

The data processing unit 40 calculates the intensity of infrared radiation energy detected from each of the first infrared sensor unit 10 and the second infrared sensor unit 20, Create a thermal overlay image.

That is, the data processing unit 40 receives the electric signals generated according to the calculation of the intensity of the infrared radiation energy detected from the first infrared detection sensor unit 10 and the second infrared detection sensor unit 20, The thermal image is generated so as to be expressed by the thermal value and the thermal value, and the thermal image sensing region according to the temperature change is detected in the generated thermal image. The data processing unit 30 may display a thermal image sensing area on the actual image obtained by the camera unit 30 to generate a thermal image overlay image.

On the contrary, a thermal image overlay image will be described below with reference to Figs.

Referring to FIG. 6, the data processing unit 30 displays the infrared detection area of the first infrared detection sensor unit 10 and / or the second infrared detection sensor unit 20 on the actual image regardless of the temperature Create a thermal overlay image. At this time, as shown in FIG. 6, the infrared sensing area displayed on the actual image may be displayed in a rectangular shape having a semi-transparent or opaque frame.

Assuming that the horizontal and vertical viewing angles of the infrared ray detecting sensor units 10 and 20 are 60 degrees and 15 degrees and the horizontal viewing angle of the camera unit 30 is 120 degrees, the two infrared ray detecting sensors 10 and 20, The data processing unit 30 may be configured such that at the center of the actual image obtained by the camera unit 30 as shown in Figure 7, It is possible to generate a thermal image overlay image in which the sensing area is displayed. 8, when the first and second infrared detection sensor units 10 and 20 are both used, the data processing unit 30 may be configured to detect the position of the second infrared ray sensor unit 20, It is possible to generate a thermal image overlay image in the center of the actual image, in which an infrared detection area corresponding to a viewing angle of 60 degrees * 30 degrees in the horizontal and vertical directions is displayed. As described above, the size of the infrared detection area displayed on the actual image may be varied depending on whether one or both of the first infrared detection sensor unit 10 and the second infrared detection sensor unit 20 is used.

Referring to FIG. 9, the infrared sensing area displayed on the actual image may be moved in the actual image according to the user setting. For example, the infrared detection area can be basically located at the center of the actual image and can be moved in the horizontal and vertical directions in the actual image by user operation. However, the infrared sensing area that is moved by user operation can move within a range that does not deviate from the real image area.

Next, the data processing unit 30 determines whether a temperature change occurs in the infrared detection area of the first infrared detection sensor unit 10 and / or the second infrared detection sensor unit 20 (for example, If a thermal image sensing area is detected, a thermal image overlay image may be generated in which the thermal image sensing area is displayed in the infrared sensing area.

For example, the thermal image sensing area may be displayed in a rectangular shape having an opaque border of a specific color and a translucent inner portion, as shown in Figs. 10 and 11. Fig. That is, the thermal image sensing area may be displayed in yellow as a warning level as shown in FIG. 10 according to a set temperature reference value, and may be displayed in red as a warning level as shown in FIG. Here, the attention level is a stage in which a fire does not occur but needs to be inspected, and a warning level may be defined as a stage in which an emergency inspection is required because a fire is likely to occur. Accordingly, the temperature reference value of the path level can be set higher than the temperature reference value of the attention level.

And, depending on the setting, a caution or warning level can be selectively used. In other words, if only the caution level is used, the area can be displayed only in yellow if it exceeds the temperature reference value of the caution level. If only the warning level is used, . Caution If both the level and warning level are used, if the temperature level is above the warning level and below the temperature level of the warning level, the corresponding area will be displayed in yellow. If the temperature level is above the warning level, the corresponding area will be displayed in red have.

In accordance with the thermal image event popup interlocking setting, a pop-up may be generated to notify the user when an abnormal temperature reference value of the warning or warning level occurs.

Additionally, a mask may be applied to monitor only a specific region of the infrared sensing area. For example, when the mask is not applied, a thermal image sensing area is detected in the entire infrared sensing area of the first infrared sensing sensor part 10 and / or the second infrared sensing sensor part 20, , It is possible to detect the thermal image sensing area in the area set by the mask.

The monitor unit 50 outputs a thermal image overlay image in which the thermal image sensing area corresponding to the temperature change generated by the data processing unit 30 is displayed on the actual image. This thermal overlay image allows the user to more accurately determine which temperature distribution each of the subject and its surrounding objects has, and which portions of the subject have higher and lower temperatures.
