<p><P>PROBLEM TO BE SOLVED: To provide the sketch figure creation/recording support system of an exposure stratum and an exposure base rock for achieving power saving, high accuracy and high operation of the power saving of a sketch operation, and for communicating records with high practical use in which a technical opinion is incorporated in an image to the following generations without deteriorating it, and for prolonging the lifetime of the structure, and for storing basic data whose additional value is high in the case of achieving maintenance management. <P>SOLUTION: Members for reference scale plotting are arranged into a grid-like structure in a photographic object area, so that a grid-shaped reference scale can be formed; the three-dimensional coordinate values of at least three cross points of the grid-shaped reference scale are measured, and are defined as reference points on the same plane; the reference points are projected by using a digital camera whose internal locating elements are already known so that a photographic object area can be photographed; and image processing is carried out by using the photographed image information and the three-dimensional coordinate information of the three reference points and the values of the internal locating elements of the camera so that the orthographic projection figure of the photographic object area can be created, and a sketch figure based on a digital image is created. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
