<P>PROBLEM TO BE SOLVED: To provide an optical axis direction specification method for solving the problems of prior art and capable of reducing the expense and the installation space without being affected by the presence of a magnetized magnetic field, and to provide optical axis direction specification device and program. <P>SOLUTION: The optical axis direction specification method includes a main image acquisition step for acquiring a main image, a reference image acquisition step for acquiring a reference image, a spatial information acquisition step for acquiring the position and the imaging direction of the reference camera, an image collation step for extracting a main image and a collation part from the reference image, and determining the center point of the main image from the collation part, and an optical axis direction specification step for specifying the optical axis direction of an imaging camera on the basis of the center point of a main image determined by the image collation step, the position of a reference camera and the imaging direction acquired by the spatial information acquisition step. <P>COPYRIGHT: (C)2013,JPO&INPIT |
