Abstract: In the face of a large number of accurate measurement of human body, a complete
automatic measurement method based on mesh model is constructed in this paper. Firstly, The point
cloud is modeled to generate the mesh model. Secondly, a cutting direction and slice thickness
adaptive slicing are proposed to deal with the mesh model, and a series of two-dimensional cross
sections are obtained. Thirdly, the analysis method of convex analysis and cross section within the
containment section automatically find the characteristics of the human body landmarks. Finally, the
accuracy and repeatability of real male model and female mode are tested, and the results show that
the method is effective.

Key words: anthropometry, triangulation mesh, slice, human boundary
