Abstract: Format processing of 3-D body scan data is carried out through analyzing the data file structure,and then key data points of each hierarchical level are extracted.The improved Delaunay triangulation algorithm is used to these key points construct these key points into triangular plane and determine the relationship between the key points,and construct the OBJ file format model which can be recognized by commonly used 3-D modeling software,thus the corresponding human body virtual model is obtained.The experimental results show that this data processing method is simple,rapid and suitable to the establishment of massive individuality manikin models.
