Fast 3D point cloud ear identification by slice curve matching

Current 3D ear identification methods require capturing ear range image data to work. In this work, based on slice curve matching, a new 3D point cloud ear identification approach is presented. Aiming to acquire 3D point cloud ear data in a low cost way, line structure light data sampling system is also introduced in this work. Experimental results and some comparisons show the comparable advantages in recognition speed and performance of the proposed method over existing range image data ways.
