    摘要: The present invention relates to a displacement detection method for detecting a displacement from phase singularities before and after the displacement, a displacement detection device, a displacement detection program, a feature point matching method and a feature point matching program. The displacement detection method for detecting the displacement from the phase singularities before and after the displacement acquires predetermined specifies the phase singularities based on predetermined elements by acquiring the elements from a phase structure of the phase singularities, and detects positions of the phase singularities. Hence, it is possible to reliably specify the phase singularities before and after the displacement, and easily and reliably detect the displacement. Various displacements, including rotary displacement, are detectable.
