Abstract
The paper describes a 3-D measuring system for the acquisition of characteristic shape features. It enables an adapted digitising strategy: acquirement of characterising elements - generating a surface topology - surface description. The procedure works on light contours in 2-D images. These light contours assign feature lines to surface characteristics which occur under varying lighting. Because of the given connection of 2-D image data with 3-D surface co-ordinates the feature lines could be founde in the point cloud. Thus, the innovation of the strategy is to be seen in the simultaneously processing of 2-D and 3-D data which allows the context-sensitive acquirement of information in physical models. The range of application of the system will cover styling, concept modelling, product development, rapid prototyping and reverse engineering technologies.
