3D Object Recognition by Surface Registration of Interest Segments

An object recognition system Based on registering repeatable interest segments from 3D surfaces is presented. The strength of this approach lies in its independence of local features, which can be unreliable when corrupted by noise, and indistinct for certain objects and surfaces. The proposed framework is Based on recent advances in segmenting 3D data into repeatable interest segments, followed by efficient surface registration of model and scene segments, where pose clustering returns the best pose candidates. A quality measure Based on reprojection of the model points and pose refinement are then used to select the best pose. The proposed method is demonstrated experimentally to be both accurate and robust when tested against a variety of partially occluded free-form objects in cluttered scenes, achieving an average accuracy of 93% on an accurate and high resolution LiDAR data set, and 81% on a noisy and low resolution Kinect data set.
