Attribute Assignment to Point Cloud Data and Its Usage

Abstract

In recent years with the development of laser measurement technology utilization of point cloud data is progressing However since point cloud data does not contain attribute information the usability of the data is low It is possible to consider that by assigning attributes to the nonattribute point cloud data this can lead to the usage of point cloud data in each phase of life cycle of construction design construction and maintenance Therefore in this paper the authors have proposed an attribute assignment method for point cloud data In addition the authors proposed the way to use attributed point cloud data the usage as objects data linkage and visualization by using the attribute assignment method Point cloud data of a dam was used as a case study for the proposed method and the usage
