3D laser range scanners are used in extraction of the 3D data in a scene. Main application areas are architecture, archeology and city planning. Thought the raw scanner data has a gray scale values, the 3D data can be merged with colour camera image values to get textured 3D model of the scene. Also these devices are able to take a reliable copy in 3D form objects, with a high level of accuracy. Therefore, they scanned scenes can be used to validate the experimental results achieved with 3D reconstruction algorithms based on multiple view camera images or image sequences. These applications of the 3D scanners can be achieved via the external calibration of standard cameras with respect to the 3D scanner. For this, multiple images from standard cameras are taken by placing them on the scanner by manual calibration. This project aims to develop methods to efficiently calibrate the cameras that are arbitrary positioned in a scene with the 3D laser range scanner and register the images with the 3D data.
