PROBLEM TO BE SOLVED: To prepare a remote construction supporting image for which a finishing stake is installed. SOLUTION: While using a pair of image pickup machines 5 for applying a pair of stereo operating images Iw of an image pickup object corresponding to a view point V, optical axis O and image angle W, a pair of initial operating images Iw1 of a target having known coordinates are photographed with an initial view point V1 , initial optical axis O1 and fixed image angle Ww and while using a three-dimensional graphic means 30 for preparing a pair of stereo design images Ie at a point designed on certain coordinates corresponding to the view point, optical axis and image angle, paired initial design images Ie1 of the target are prepared at the initial view point V1 , initial optical axis O1 and arbitrary image angle Wx . While superposing the paired initial operating images Iw1 and the paired initial design images Ie1 , the arbitrary image angle Wx is changed and an image angle We of the graphic means 30 corresponding to the image pickup machines is decided so that the images of all correspondent targets 8 can be coincident. The paired operating images Iw of a constructing object 1 is photographed at a prescribed view point Vi , prescribed optical axis Oi and the fixed image angle Ww , paired design images Ie are prepared at the prescribed view point Vi , prescribed optical axis Oi and the image angle We corresponding to image pickup machines, and the paired operating images Iw and the paired design images Ie are superposed so that paired supporting images Ii can be prepared. |
