The splicing and three-dimensional measurement of the hydraulic turbine blade is achieved in this paper. The large size of hydraulic turbine blades makes it impossible to take a complete picture of the entire blade. Multiple images of various segments must be obtained and then spliced together at later stages. Landmarks are installed in public area of the adjacent segments of hydraulic turbine blades, which are used when splicing segmental images together using least squares method, to obtain three-dimensional surface information ofthe entire blade. Based on the principles of the structure light measurement, a three-dimensional measurement system is designed, its parameters are also defined, and mathematical models of the three-dimensional measurement are established. The hydraulic turbine blade is simulated by using software package “3ds max” to build a hydraulic turbine blade model. Simulation of splicing and three-dimensional measurement of the hydraulic turbine blade shape is achieved. The reconstruction of the three-dimensional Hydraulic turbine blade is then obtained based on the measured data.
