Abstract:
1. A three-dimensional image display apparatus comprising: a stereo image data storage section for storing stereo images, photographed in different angles from each other, of a measuring object; a corresponding point designating section for designating corresponding points on the stereo images; an orientation section for finding a relationship as to corresponding points in the stereo images based on a position and a tilt at which the stereo images are photographed, using the designated corresponding points; a three-dimensional coordinate data section for obtaining three-dimensional coordinate data on the corresponding points of the measuring object based on the relationship as to the corresponding points found by the orientation section; a model forming section for forming a model of the measuring object based on the three-dimensional coordinate data on the corresponding points; an image correlating section for correlating the stereo images of the measuring object stored in the stereo image data storage section and the model formed by the model forming section, using the relationship as to the corresponding points found by the orientation section; and a model display section for displaying an image of the measuring object to which stereoscopic texture is applied, using the stereo image correlated with the model by the image correlating section, wherein the corresponding point designating section is configured to pull in a point, which is designated by an operator on each of the stereo images, to a characteristic point in a vicinity of the point designated by the operator, and to indicate the characteristic point in each of the stereo images displayed on a display device, and to make the designated corresponding point of the characteristic point, the designated corresponding point to be used by the orientation section, wherein the characteristic point is a gravity center position of a target given on the measuring object or a corner characteristic point, and an area where the target or the corner characteristic point lies is decided based on the point designated by the operator, and the gravity center position of the target or the corner characteristic point is calculated in the area.
