Research on Measurement Technology of Large-scale Hull Curved Plate Based on Depth Camera
A measurement system of hull curved plate based on depth camera was designed.The system combined depth camera with servo drive,and used computer to control the acquisition process to ob-tain multiple groups of small-range point clouds at designated positions.An improved region growing segmentation method based on hyper-voxel clustering was used to extract the surface point cloud of curved plate from the original point cloud data.Through the relative position of camera installation and the return parameter value of servo system,the complete three-dimensional point cloud of hull curved plate was spliced.The system was used to measure the curved hull plate in the range of 3000 mm× 3000 mm.The average error of non-edge point cloud is 0.61mm,which meets the expected ac-curacy requirements.
