DEVELOPMENT OF CORRECTION SYSTEM ON THE TWO-DIMENSIONAL DRAWINGS OF THE UNDERGROUND BURIED OBJECTS USING THREE-DIMENSIONAL MODEL BASED ON A SIMPLIFIED MEASUREMENT DATA

Abstract

 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 using a simple 3D model generation method for underground buried objects. In this research, the authors have developed an existing 2D drawing correction system, applied a 2D drawing correction method using a 3D model in the realization field, and verified the accuracy of a 3D model and the 2D drawing correction method. As a result, the authors extracted image data from the generated 3D model, and confirmed that the drawings can be corrected quickly by combining the extracted image data and the existing 2D drawings.
