Co-registration of Time-of-Flight (TOF) camera generated 3d point clouds and thermal infrared images (IR)

This article presents an investigation on the co-registration of a 3d point cloud and intensity image of a near-infrared (NIR) time-of-flight (TOF) camera system and a thermal infrared (TIR) camera. The TIR-camera is relatively oriented to the TOF-camera. As the radiometric behavior of the TIR-camera and the NIR-image of the TOF-camera is different for most pixels, corners are detected in both images and co-registered. The intensity values of TIR-camera are projected into the TOF point cloud and from there in the TOF-camera image plane. The quality of the projection is evaluated comparing the projected TIR image from the view of the TOF-camera and the TOF NIR image.     «
