CAMERA MOTION INFORMATION ACQUIRING APPARATUS, CAMERA MOTION INFORMATION ACQUIRING METHOD, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a camera motion information acquiring apparatus for automatically finding a three-dimensional position and a posture of a camera in all images of a long image sequence taken by a time-series image inputting apparatus such as a video camera when the images are taken.;SOLUTION: The camera motion information acquiring apparatus is provided with a moving/observed image sequence acquiring means 11 for acquiring the image sequence observed by the moving image inputting apparatus, a moving/observed image sequence dividing means 12 for dividing the acquired moving/observed image sequence into a plurality of sub-image sequences as a plurality of the images are overlapped between the sub-image sequences, a coordinate system integrating means 13 for integrating different coordinate systems between the sub-image sequences into a common global coordinate system, and a camera motion re-estimating means 14 for re-estimating a camera motion in the common global coordinate system.;COPYRIGHT: (C)2008,JPO&INPIT
