Japanese Patent JP5915996

B2

PROBLEM TO BE SOLVED: To provide a synthetic image display system for synthesizing a pick up image with a virtual image to display an exact construction completion image without using an AR marker in a portable imaging terminal in a building under construction.SOLUTION: A synthetic image display system is constituted of: a portable imaging terminal; and a data server, a three-dimensional computer graphic image of a building under construction is preliminarily written to be stored in the data server, and the portable imaging terminal includes: an imaging part which picks up an image in the building to be output as a pick up image; a display part which displays the pick up image; a position control part which compares coordinate positions of the same feature point at the same position in the pick up image and a virtual image at the same position and the same imaging direction obtained by picking up the pick up image in the computer graphic image; and an image processing part which performs coordinate conversion that the coordinate positions of the feature point overlap each other by a comparison result of the coordinate positions of the feature point to overlap the virtual image with the pick up image to be displayed on the display part.
