Provided is a system for displaying a 3D thermal image by using two thermal imaging cameras and extracting distance/depth data in the thermal images. The system includes two thermal imaging cameras where one thermal imaging camera is used as a master camera serving as a reference and the other is used as a slave camera to correct gain and offset of the thermal images and ensure uniformity. In addition, provided is an apparatus and method for correcting gain and offset of the thermal images to be identical to each other and ensuring uniformity by using a process module separately from two thermal imaging cameras. Therefore, since temperature data is overlaid on the 3D thermal image or the thermal imaging data from which disparity from two cameras is extracted, it is possible to provide more accurate and diverse subject recognition information in comparison to an existing device which provides just a 3D image or an infrared image solely. In addition, since temperature data is overlaid on a 3D thermal image or the thermal imaging data from which disparity from two cameras is extracted by processing only data about a partial area of interest (temperature area, image area) among the entire thermal image for the purpose of high-speed frame processing, it is possible to rapidly provide more accurate and diverse subject recognition information in comparison to an existing device which provides just a 3D image or an infrared image solely.
