Paper Abstract

Recent work on the task of automating sensor placement for inspection has focussed primarily on deriving a single view of a set of object features that will satisfy a set of basic inspection requirements. From a single view, however, accurate dimensional inspection cannot be carried out. This goal can only be achieved through the use of multi-station sensor configuration in combination with the method of optical triangulation. In this paper, fundamental issues regarding the design of multi-station configurations are addressed. Firstly, the bundle method is introduced as a powerful and flexible mathematical tool for the estimation of object feature coordinates and analysis of the quality (precision and reliability) of these estimates. Secondly, basic considerations leading to the design of configurations which satisfy accuracy specifications are reviewed. The impact of these considerations on the placement of individual sensor stations is examined. Finally, development of an expert system being built on the expertise of photogrammetrists and design considerations knowledge for automating the design of multi-station configurations task is outlined.
