Abstract
3D point cloud data is used widely and applications of the data are studied actively in many research fields. In our previous paper, we illustrate an analysis method to set data the attribute of the st ructure which is located roadside. However it is very difficult to distinguish to an electric pole and a signal only using positional information of data.
This paper studies an analysis method of setting data attribution of structures using color informa tion. We describe a method to sort data in a hue(H) and saturation(S), and as an example ,show the result of sorting for attribution of point cloud data which are measured national road. Since each point has a color and position information, positions are automatically identified.
