We describe a technique for using geometric information contained in 2D images to search large databases of 3D models in the special case where the geometric information consists of finite point configurations. This technique exploits certain polynomial relations known as object/image equations between invariant coordinates assigned to 2D and 3D feature sets. The resulting scheme is invariant to changes in scale and perspective. Techniques for constructing indexes based on this technology as well as experimental results on numerical stability will also be described.
