Improved Reach Zone and View Scope Algorithm of Software Jack

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.
