3D visualization of measurement data is one of the key approaches in laser tracking measurement data processing. Combining with the development of laser tracking measurement software system, technical characteristics and architecture of VTK are studied in this paper. The classes and interfaces for measurement data processing and displaying are also designed and implemented. Furthermore, based on the platform of Microsoft Visual Studio 2010, a measurement data processing and 3D visualization software is developed using C++ and VTK, achieving functions of point cloud fitting, 3D graphics display and user interaction. The effectiveness and usability of the software are testified by experiments which show that VTK has great application value and potential in the field of industry measurement visualization.
