Pose Normalization of 3-D Mesh Model Based on Rotation Transformation

A novel method for pose normalization of 3-D mesh models was put forward based on rotation transformation. Via the theory of analytic geometry,this paper analyzed the rotation transformation of a plane,a projection transformation revolving about a basis vector,and developed the computational formula of rotation angle. We also achieved the computable rotation matrix for mesh models through further research integrating with computational graphics and probability theory. As a result,a mesh model with arbitrary...
