Document Type and Number:
Japanese Patent JP7287563
Kind Code:
B2
Abstract:
A projection transformation parameter for guaranteeing a deformation to a convex quadrilateral can be calculated even when one or more of correspondence points are errors. A projection transformation parameter estimation device according to an embodiment includes a correspondence point detection unit (1) configured to detect information about a correspondence between two pieces of input data, a quadratic surface calculation unit (2) configured to fit a quadratic surface to the information about the correspondence for one or both of the two pieces of the input data, and a projection transformation matrix calculation unit (3) configured to calculate a projection transformation parameter between the two pieces of the input data by using the information about the correspondence with a constraint condition specifying that a property of the quadratic surface is maintained even after projection transformation.
