MOVING OBJECT MEASURING APPARATUS, MOVING OBJECT MEASURING SYSTEM AND MOVING OBJECT MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a moving object measuring apparatus that can easily acquire a three-dimensional trajectory of a moving object. SOLUTION: The moving object measuring apparatus comprises: a movement trajectory information acquisition part that obtains movement trajectory information indicating a movement trajectory of a moving object from images included in two or more video sequences that are stored, for each of the two or more video sequences separately; a three-dimensional trajectory information acquisition part that obtains three-dimensional trajectory information that is information on a three-dimensional trajectory of the moving object by using a visual hull method, based on the movement trajectory information obtained by the movement trajectory information acquisition part for each of the two or more video sequences separately and two or more camera parameters that are stored; and a three-dimensional trajectory information output part that outputs the three-dimensional trajectory information. The three-dimensional trajectory of the moving object can thus be measured easily. COPYRIGHT: (C)2007,JPO&INPIT
