JIG FOR SYNTHESIZING IMAGE OF COLOR CAMERA AND THERMAL CAMERA

摘要

The present invention relates to a jig for synthesizing images of a typical color camera and a thermal camera, capable of correcting a viewing angle and a distortion degree according to a physical position relationship between an image of the typical color camera and an image of the thermal camera to synthesize the images into one image. The jig for synthesizing the images according to the present invention, which provides a reference position in order to synthesize images of the typical color camera and the thermal camera into one image, includes: a white background plate (10) formed therein with rectangular holes or circular holes spaced at a predetermined distance in longitudinal and transverse directions; and a black inner plate (20) detachably coupled to a rear surface of the white background plate (10) to express the holes formed in the white background plate (10) in black. When the white background plate and the black inner plate are photographed by the thermal camera after the white background plate and the black inner plate are stored in a normal-temperature state and a cooling state and coupled to each other, the black rectangular or circular patterns can be extracted according to the temperature difference between the white background plate and the black inner plate.
