How well performs free-form 3D object recognition from range images ?

Hügli, Heinz ; Schütz, Christian L.

In: Photonics East (Proceedings of SPIE), 1996, vol. 2904, no. 9, p. 66-74

This paper investigates the recognition performance of a geometric matching approach to the recognition of free-form objects obtained from range images. The heart of this approach is a closest point matching algorithm which, starting from an initial configuration of two rigid objects, iteratively finds their best correspondence. While the effective performance of this algorithm is known to depend...

Towards the recognition of 3D free-form objects

Schütz, Christian L. ; Hügli, Heinz

In: 3D Pattern Recognition for Intelligent Robots, Intelligent Robots and Computer Vision XIV : Algorithms, Techniques Active Vision and Material Handling (Proceedings of SPIE), 1995, vol. 2588, p. 476-484

This paper investigates a new approach for the recognition of 3D objects of arbitrary shape. The proposed solution follows the principle of model-based recognition using geometric 3D models and geometric matching. It is an alternative to the classical segmentation and primitive extraction approach and provides a perspective to escape some of its difficulties to deal with free-form shapes. The...
