DEVICE AND METHOD FOR MEASURING THEREE-DIMENSIONAL POSITION AND RECORDING MEDIUM RECORDING THREE- DIMENSIONAL POSITION MEASURING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for measuring a three-dimensional position and a recording medium recording a three-dimensional position measuring program capable of correctly measuring a marker position thereafter by correcting the position of a marker and the position of a measuring window in real time in the case that the proximity or crossing of the marker is generated. ;SOLUTION: Data for resetting the position of the measuring window from relative position relation with the other marker are calculated and stored for the respective markers and a prediction range to set the measuring window is calculated based on a measured result at the time of initialization. In the case of measuring that the marker is on the outside of the prediction range exceeding fixed time, the measuring window is reset from the position relation with the other marker based on the stored data.;COPYRIGHT: (C)2001,JPO
