【Abstract】 Based on the scattered 3D data obtained by optical tracking localizer, an approach of linear approximation was applied in a triangular mesh approximation for an unknown surface. The empirical formula of neighborhood values of the space point was introduced and used in the surface reconstruction of joint navigation. The results of the simulation on a cadaver show that this method is more effective and can realize a quick real-time visualization in the surgery and avoid the error in linear interpolation.更多还原
