Abstract
Due to the spread of three dimensional measurement devices such as MMS, ground based laser scanner and camera mounted UAV, the technology concerning practical use of the measured point cloud data has attracted attention. In addition, as a part of the measures of “i-Construction” promoted by the Ministry of Land, Infrastructure, Transport and Tourism, the as-built management, and the supervision and inspection guidelines using point cloud data are published, and it is expected to increase the utilization scene of point cloud data in future. In order to effectively utilize point cloud data, it is necessary to extract road objects from them. Therefore, many previous researches analyze the shape and position information to extract objects. But it is difficult to extract road objects comprehensively. Thus in this research, we propose a method to extract road objects from point cloud data referring to the road completion drawing on the road construction completion reports.
