摘要：

Reverse engineering (RE) is widely used on the aspects about designing of advanced products, software or images. The 3D Geometric modeling method is composed of measurement equipment and RE software. The three-dimensional digital measurement equipment is used to collect the model's point cloud data and reconstruct CAD model. Geomagic Studio is widely used to process data and repair models, while Geomagic Qualify is widely used in testing of reconstruction model. The point cloud data of a turbine blade is collected and processed, some technologies and steps including pre-processing of point cloud data, polygon processing, surface fitting, triangular mesh, model smoothing and polygon mesh optimization are conducted. Finally, it is being demonstrated that 3D Geometric modeling method in Reverse Engineering is successful.
