<P>PROBLEM TO BE SOLVED: To create and obtain high-precision position information by performing calibration, giving the absolute coordinates to be obtained by a GPS or the like to a camera vector that represent the position and the rotational angle of a camera. <P>SOLUTION: This arithmetic unit is provided with a mobile unit measuring portion 10 for performing measurement for position measured data of a mobile unit, along with obtaining the video image of the periphery of the mobile unit, a data generating portion 20 for acquiring the measured position measured data, along with generating CV data representing the three-axis rotational position and triaxial rotational position of the camera from the obtained video image, a time base matching portion 30 for generating the CV data and the positional measured data into time synchronized CV data and time synchronization measured data related by reference time, a CV-correction portion 40 for generating a CV-correction signal for performing complementation correction mutually by relating the time synchronized CV data and the time synchronization measured data by the same time axis and comparing them, and a high-precision CV data output portion 50 for outputting the high-precision CV value corrected by the CV correction signal, corresponding to each frame of the obtained video image. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
