| Abstract: | Based on the laser three-dimensional(3-D)digitization system with light stripe method,a grouping and deleting method is proposed to delete the stray points in the original data set,and a coordinates averaging method is proposed to splice the data sets obtained by two adjacent sensors.The principles and procedures of the two methods are described in detail.Two 3D sensors are used to measure the garment model at different position,and the measurement results are processed by the two methods.Processing results show that the final model has a smooth surface and a uniform data distribution,which truly reflects the geometry characteristics of the object. |
