PROBLEM TO BE SOLVED: To correct a positional deviation occurring when a perspective image of a building scheduled for construction and a photographed image of the planned site for the building are synthesized on a real time basis.SOLUTION: An information processing device comprises; a memory in which three-dimensional data representing planned position coordinates of a building scheduled for construction and the pertinent building and topographic data including the heights in different positions in a prescribed range covering the planned position coordinates are stored; a camera; a position sensor; a direction sensor; a display unit; and a control unit. The control unit draws a perspective image of the building from the viewpoint of the camera on the basis of the three-dimensional data, the planned position coordinates, current position coordinates and the direction, causes a synthesized image resulting from superposing the perspective image over the photographed image to be displayed on the display unit, and can use, for drawing the perspective image, a value resulting from adding the average height of a human viewpoint to a height in the topographic data as the correcting value in the perpendicular direction of the current position coordinates.SELECTED DRAWING: Figure 5 |
