Displacement method of detection, and displacement detection device, displacement detection program, and feature point matching processing method, feature point matching program

摘要

This invention being the displacement method of detection which detects displacement from the phase singularity of displacement front and back displacement method of detection, and the displacement detection device which detect displacement from the phase singularity of displacement front and back, the displacement detection program, and feature point matching processing method, in regard to the feature point matching program, to acquire the specified element from phase structure of the phase singularity, the phase singularity specify on the basis of the element, the phase singularity of displacement front and back specify securely by detecting the position of the phase singularity after the displacing, that displacement easy, at the same time, certaintyFurthermore, the various displacements which include revolution displacement it features that it makes detection possible.
