%X To meet the needs of identification through stereo bare footprint,this paper proposed a method for comparability determination of 3D surface based on LIM(Lorentz Information Measure).Taking gauss curvatures and normal vectors as random variables,Lorentz Curve was extended to 3D Lorentz Surface.Reflecting the difference of information measure of two 3D surfaces,the volume between two Lorentz Surfaces was used to determinate the comparability of the two 3D surfaces.The experiment on stereo bare footprint surface indicates that our method is valid.
