Abstract

This paper explores the theory and algorithm for the measurement and reconstruction of line industrial objects based on CAD representation, and proposes a mathematical model for line photogrammetry. In the model, the geometric elements based on CAD representation describing industrial objects are considered as unknowns and match directly from image to object. Furthermore, this paper presents an application prototype which includes the system configuration and the method of system calibration. Finally, the measurement results and a discussion are put afterwards.
