In urban areas, it is expected that the number of businesses such as reconstruction, renewal, and the construction of new structures will be increased in areas where there is a large volume of remarkably deteriorated infrastructure equipment and underground buried objects. However existing structures are usually managed by two-dimensional drawings, it is difficult to determine the position and height of underground objects during construction works.
The purpose of this research is to establish efficient correction system for the existing 2D drawings, by improving the simple 3D model generation method for underground buried objects.In this research, the authors applied a 2-D drawing update method using the system developed for improving the correction efficiency in the realization field, and compared and verified the working time of the conventional method and the devised update method for practicality.As a result, it was confirmed that the image data can be extracted from the generated 3D model and superposed on the existing 2D drawing to correct the drawing quickly.
