Title:
IMAGE PROCESSOR AND ITS METHOD AS WELL AS PROGRAM CODE AND STORAGE MEDIUM
Document Type and Number:
Japanese Patent JP3486613
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To correct the measuring errors of an attitude sensor at a camera eye point and achieve MR with no dislocation by correcting accumulative errors in a sight direction caused with the lapse of time, in particular.
SOLUTION: Firstly, a template image is drawn (S501). Then, an image It is photographed (S502). The output of a sensor is also acquired at this time (S503). A model view matrix Mt is calculated in accordance with the output of the sensor (S504). A correlation matrix ΔMt is calculated (S505). The model view matrix Mt is corrected by using the calculated correction matrix ΔMt (S506) and CG is plotted and displayed by using the corrected model view matrix (S507).
