Optimal camera placement for an active-vision system

Image-analysis in an industrial environment can be simplified by premarking the objects using artificial markers and active vision to acquire prespecified views of these objects. In this context, a problem addressed is the determination of the initial locations of the cameras (including one mobile camera) such that marker(s) can be efficiently detected. A method for determining the optimal number of cameras and their best locations is presented, given the objects' geometries and the positions of markers on them. Such an optimal camera arrangement would yield maximum detectability of markers and also satisfy a user given threshold on the probability of detecting at least one marker. Analytic-geometry, probability theory and CAD databases are used in solving this problem.>
