Method for hidden surfaces attitude analysis based on photogrammetric technique

For many applications it is important to know how two adjacent parts of a system are located. Measuring outer parameters of parts is relatively simple task. But it is a problem to determine relative attitude of inner surfaces of adjacent parts and to measure given parameters of conjunction. Such applications as manufacturing, dentistry have a need for a solution this problem. A photogrammetric method for hidden surfaces attitude analysis is developed. It uses original photogrammetric system for parts’ surface reconstruction, 3D model alignment in the position according real parts joint and 3D model joint attitude analysis. The developed technology is demonstrated for dentistry application (jaws occlusion analysis).
