Abstract： In this work, several key techniques for the development of engineering equipment virtual training system are addressed. Firstly the reconstruction method for three views of machine parts is proposed based on rapid 3D surface fitting as well as NURBS composite surface. Then the interactive control techniques for the 3D visualization interactive assembly is studied in detail. The key technology of collision detection is also illuminated in the last. The entire construction machinery support training system, that includes structure expressing, principle demonstration, panoramic roaming, disassembly training as well as maintenance and repair training, is developed.
Key words：virtual training system；engineering equipment；3D model reconstruction；collision detection
