- Based on the structured light technology, a new study method and system of concentricity measurement of marine propulsion shafting is researched in this paper. The system is consisted of the image information acquisition, the structured light calibration and three-dimensional 3D scanning point cloud data processing. Image information acquisition function is implemented by the hardware part, this part mainly by CCD camera, laser, mechanical rotary table and computer hardware. Image information acquisition is used by the two-dimensional 2D laser triangulation method. The structured light calibration is based on the internal parameters of the camera and relative external parameters to establish relationship between the image of 2D coordinates and object of the 3D coordinates. The 3D scanning point cloud data processing is included reduction and merging on multi view measurement data. Based on multi view measurement data, an improved ICP algorithm is proposed. This system can provide a new method and a new idea for the concentricity measurement of marine propulsion shafting.
