A digital photo studio was built to generate high quality real world input data for various imagebased rendering and vision algorithms. Special attention was paid to carefully control the lighting conditions in order to be able to acquire exact data about the surface properties of objects using readily available digital camera technology. This paper discusses the specific demands and requirements that arise from these goals for the equipment in the photo studio. Furthermore, we describe the typical workflow for one of our current projects, thereby illustrating the interoperation between the different devices. 1 Introduction The need for more realistic input data for various image-based rendering and vision algorithms increases more and more. In addition to traditional multimedia applications, e-Commerce seems to be a driving force for new developments. Before buying a product online shoppers would like to get a visual impression of the product that is at least as good as the impress...

Abstract — This paper presents a new registration algorithm of 2D color images and 3D geometric models for navigation system of surgical robot. A 2D-3D registration procedure is used to superimpose a tumor model on an endoscopic image precisely, and is therefore indispensable for the surgical navigation system. And thus, the performance of the 2D-3D registration procedure influences directly the usability of the surgical robot operating system. One of the typical techniques developed so far is the use of external markers, but the accuracy of this method is getting worse due to the breath, the heart beat, or other unknown factors. For precise registration of 3D models and 2D images without external markers or special measurement devices, the new registration method is proposed which utilizes the 2D images and their distance maps created by the Fast Marching Method. We show some results of fundamental experiments using simulated models and actual images of the endoscopic operation. I.
