Object-oriented Loading and Organization on Points Cloud Data of Urban Building

Three dimensional points cloud data are analyzed by using object-oriented programmer,and the computer-based realization,which is organized by points cloud data of urban building captured by laser scanning,is studied based on image process on the exploration platform of Visual C++6.0.The unique global indexes of valid target points are determined by scanning relationship between points.The image range corresponding to the global indexes is fixed on by taking points cloud data as a range image.The points cloud data are classified and organized by calculating the normals of all corresponding points by using the image ranges obtained before.The experimental results indicate that loading and organizing three dimensional points cloud data can be implemented easily and quickly by using object-oriented image technique.
