Abstract: By the 3D body measurement system developed by our team, the 3D body scan line point cloud can be acquired. For the complexity of the human body surface, if directly construct the body surface model, it may cause arms with torso, left leg with right legs together as one, or big errors in the head-shoulder with the arms and the torso and the torso with legs. So the paper first partitions the human body surface into six parts based on the shape of the human body, and constructs the triangular mesh for each part, then put forward a new method that divides the single contour into multi-contour to triangularize the head-shoulder with the arms and the torso and the torso with legs, eventually, the triangular mesh surface model of the entire human body is constructed.

Key words: 3-D body measurement, scan line point cloud, partitioning of body, single contour, multi contour, triangular mesh model
