OLD/NEW VIDEO IMAGE COORDINATE INTEGRATION UNIT

PROBLEM TO BE SOLVED: To enable representation with an identical coordinate system by obtaining a corresponding point between a new video image and an old video image even when the camera, climate, imaging condition, visual point direction, etc. are changed. SOLUTION: A video image integration unit includes: a reference video image section 101 for retaining a reference video image; a CV addition section 102 for adding a predetermined CV value to the reference video image; a three-dimensional reference point specification section 103 for obtaining the three-dimensional coordinate of a reference point by specifying the reference point in the reference video image; a comparison video image section 104 for retaining a new video image to be compared with the reference video image; an initial position set section 105 for performing initial setting of the correspondence of common places between the reference video image and the comparison video image; a reference point corresponding section 106 for searching in the comparison video image a corresponding reference point corresponding to the three-dimensional reference point through a plurality of frames from an initially set frame; a corresponding reference point trace section 107 for tracing the corresponding reference point through a plurality of frames; a CV acquisition section 108 for acquiring a CV value of the comparison image by transferring the three-dimensional coordinate of the three-dimensional reference point to a corresponding reference point of the comparison video image; and a coordinate integration section 109 for coordinate-integrating the comparison video image with the same coordinate system as the reference video image.
