Improved Reach Zone and View Scope Algorithm of Software Jack

Abstract

In order to get reach zone and view scope with complete geometric information to facilitate research of collision detection, a point by point scanning algorithm was brought up to generate the spatial surface of human's reach and view area. The method to set scanning point's motion path in the beginning based on the major degrees of freedom of human's arm and the range of human's eye joints in horizontal and vertical direction. Then obtained each point's coordinates by a certain frequency. At last a curved surface was formed by these discrete points to represent human's reach zone and view scope. The surface's geometry information was stored to a file at the same time. In the algorithm the freedom of human's arm and eye was optimized especially. This can solve a variety of reach zone and view scope with arbitrary joint angles. The work facilitated the future study of collision detection and engineering analysis.
