An active triangulation 3D scanner was developed at the Budapest University of Technology and Economics, Departament of Automation. In the first part of this paper the configuration of 3D scanner system will be presented. Then the edge tracking part of model extraction algorithm will be described, especially focusing on the handing of noise. Accuracy of the generated CAD model depends of configuration parameters and the noise of the frame buffer image can be taken into consideration. The last part of the paper presents a workflow for the adequate handling of accuracy, as a function of a certain noise model. Since the development is focused on the accuracy of method instead of expensive hardware elements, it is essential to know the theoretical capabilities of the system. The focus of the paper is finding the initial point of edge tracking, the accuracy of angle calculation and the accuracy of line tracking supposing a noise model. Finally some experiment results are demonstrated.
