PROBLEM TO BE SOLVED: To provide a method for positioning an actual image and superimposition information on the image by a simple operation through the use of a comparatively simple computer. SOLUTION: The three points of marks O, A and B are respectively displayed on the image which is photographed by a terminal 1 in a jot site. As far as a segment OA is not in parallel with a segment OB when a point P is newly written on the image, a formula is expressed as ↓OP=1*↓OA+m*↓OB (an arrow is a vector and l and m are actual numbers) so as to calculate l and m. When the position and the posture of a camera are changed to obtain the three point of marks O', A' and B' on the image, P' is obtained by calculation through the use of ↓O'P'=1*↓O'A'+m*↓O'B'. |
