Abstract

We introduce a new probing problem: what is the minimum number of cameras at fixed positions necessary and sufficient to reconstruct any strictly convex polygon contained in a disk of radius 1 if cameras only see the silhouette of the polygon? The optimal number only depends on the largest angle α of the polygon. If no two camera tangents overlap, \(\lceil \frac{3\pi}{\pi-\alpha} \rceil\) cameras are necessary and sufficient. Otherwise, approximately \(\lceil \frac{4\pi}{\pi-\alpha} \rceil\) cameras are sufficient. Reconstruction only takes time linear in the number of cameras. We also give results for the 3D case.
