Various filtering techniques exist to obtain the ground from laser radar data to use when building digital terrain models. This paper develops an active shape model approach to estimate the ground surface from laser radar data. The active shape model acts like a rubber cloth with elasticity and rigidity. With constraint forces the model is formed to an estimate of the ground surface. The model is glued against the measured points from underneath, forming the envelope of the point cloud. Even in… CONTINUE READING
