ABSTRACT:
In the automatic photogrammetric 3D digitization of a body or body part marked e.g. by an envelope provided with photogrammetric target markers, the camera employed for image recording has additional light pattern projectors added thereon which are fastened to the camera body and project geometrically simple structures such as points or lines onto the body. These structures, which are visible optically without the viewing image, facilitate the manual alignment of the camera and the positioning of the camera at the correct distance from the body in obtaining the numerous overlapping individual images required for photogrammetric evaluation. This manually predefined alignment facilitates the automatic association of the photogrammetric markers in the individual image pairs with the aid of image processing methods and allows it to be carried out more reliably on an automated basis. According to a preferred embodiment, the projectors are turned off in the actual image recording process.
