The method of recording damage information on a two-dimensional (2D) exploded view, in general, has the advantage of allowing an inspection record to be easily prepared. On the other hand, it has issues in terms of the fidelity of damage positions recorded on the exploded view and the precision of ex-post analyses of damaged regions. As such, technology for saving inspection records as three-dimensional (3D) digital information is sought after. Mitsubishi Heavy Industries, Ltd. (MHI) has developed technology for obtaining and recording the areas and photograph textures of damaged regions by reproducing the position/orientation of the photo (camera) of an object to be inspected on a 3D CG (Computer Graphics) space and projecting the damaged regions indicated on the photo and the photo on the target 3D CAD (Computer Aided Design) model. This technology allows preparation of a 3D digital inspection record with the same workload and equipment as those required for preparation of a 2D inspection record, thereby improving quality control.
