3D Dynamic Thermography System for Biomedical Applications

Abstract

In this work we present a system for 3D dynamic thermography that consists of two FLIR thermal cameras and two off-the-shelf depth sensors. To generate a single 3D thermogram, the data obtained from the depth sensors is registered with the images from the thermal cameras. The process of generating a 3D thermogram is repeated several times while thermally stimulating the surface of the subject to produce a series of 3D thermograms. The advantage of this system is presence of 3D geometric data that is used to register the thermograms in the series to compensate for any movement of the subject and select regions of interest based on the subject's anatomy and easy segmentation of the body from the background.
