Pre-processing method of point cloud data by using filtering in UG secondary development and its implementation

LUO Yu,QIU Wang-biao(School of Mechanical Engineering,Guizhou University,Guiyang 550003,China)  
By means of combining UG and Matlab,a new way of point cloud data pretreatment in reverse engineering was proposed to deal with the case that,beside UG,other softwares were needed to help pre-process the point cloud data by using filtering,etc.The pretreatment was divided into three steps as ordering,reduction,and smooth filtering.Then a feasible algorithm was designed for each step,and the whole algorithmic function was implemented with the interfaces developed by using UG/OpenAPI.In the meantime,the restriction to data format displaying in UG was broke through,and the result of de-noising and filtering could be displayed in real time.The result of experiment showed that this technique could offer an application prospect of UG in reverse engineering.
