Sommario/riassunto

Due to the continuing progress of sensor technology, the availability of 3-D cameras is already foreseeable. These cameras are capable of generating a large set of measurement points within a very short time. There are a variety of 3-D camera applications in the fields of robotics, rapid product development and digital factories. In order to not only visualize the point cloud but also to recognize 3-D object models from the point cloud and then further process them in CAD systems, efficient



and stable algorithms for 3-D information processing are required. For the automatic segmentation and recognition of such geometric primitives as plane, sphere, cylinder, cone and torus in a 3-D point cloud, efficient software has recently been developed at the Fraunhofer IPA by Sung Joon Ahn. This book describes in detail the complete set of ‘best-fit’ algorithms for general curves and surfaces in space which are employed in the Fraunhofer software.

Sommario/riassunto

The concept of "centring" is used to mean "ordering the world," and Baker links this to ideas in chaos theory, which views order and disorder as mutually generative phenomena rather than static antinomies. Thus strategies to control disorder and create and maintain order may suddenly precipitate change. Baker's application of these



theories to an island nation that has received little detailed attention in the past makes this a highly original work, as does his holistic, post-modern perspective. In addition to presenting a sensitive historical analysis, he confronts the dilemma of meaning in peripheral situations and the experience of dependency in the world system. Centring the Periphery is germane to understanding the majority of the world's people and makes a significant contribution to the study of society in developing nations.
