PURPOSE:To rationalize Y design work by estimating an image pickup parameter and superposing a photographed video over a forecasted picture on the screen of a collation display means. CONSTITUTION:An image pickup parameter calculating means 13 calculates the image pickup parameter by ten image pickup magnifications and the relative position of a photographing means 10 to a measuring means 11 for collation between the object of the video in each image pickup magnification and that of the forecasted image. This calculation is repeated, and the image pickup parameter obtained at the time of coincidence between differences of vertical and horizontal relative positions of the photographing means 10 to the measuring means 11 of two objects for estimation is transferred to a storage means 6. When relative positions and attitudes of the measuring means 11 and the photographing means 10, image pickup magnifications, and the position of the optical axis of the photographing means 10 on the screen of the display means are calculated, a forecasted screen generating means 15 generates the forecasted screen of the object by the position and the attitude of the object and the image pickup parameter. The video of the photographing means 10 and the forecasted picture are outputted while superposing then on the screen. An operator inputs a signal to an information correcting means 17 to measure the position of the object. |
