Paper Abstract:	We present a method of partial matching two shapes aimed to support 3D scanning applications. The degree of matching of two shapes, that is the congruence of their overlapping portions, has been defined by a simple matching index, which should be maximized to attain the right relative placement of the two shapes. Using a simplification of one of the shapes and a sampling strategy in 6D configuration space we achieve matching in an amount of time too long for interactive applications. However, the method does not require the detection of intrinsic or artificial features (or shape descriptors), nor optical markers. By using a simple wireless tracking device attached to the object being scanned, the registration process can be made fast enough for practical, interactive 3D scanning.
