Abstract: This article gives a new method for the Deluney Triangulation of craniofacial point cloud.By dividing the point cloud into two layers，the points are connected from the upper and lower to generate a set of triangular patches;during the triangulation process，taking into account the certain holes and the difference of curvature of the facial point cloud data，the steps are classfied into four groups（usually，hole，vertebral links，sewing） to process the points separately，by taking the advantage of the smallest diagonal method.Experimental results show that the algorithm maintains a relatively accurate profile of the face and skull.
