<P>PROBLEM TO BE SOLVED: To provide a CAD working drawing checking method capable of appropriately checking a CAD working drawing and improving work efficiency. <P>SOLUTION: A leveling rod of a standard length is installed to the checking object cross section of an execution site, the photographed image of the checking object cross section of the execution site photographed including the leveling rod is fetched (S21), and the inclination of the image surface of the photographed image and the checking object cross section is detected on the basis of the photographed leveling rod included in the photographed image (S22). The inclinations of the CAD working drawing and photographed image of the checking object cross section are matched on the basis of the detected inclination (S26), the CAD working drawing and the photographed image whose inclinations match are superimposed (S27) and the superimposed image of the CAD working drawing and the photographed image is outputted (S28). Thus, the need of an adjusting operation for matching the inclination of the CAD working drawing with the inclination of the photographed image is eliminated. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
