Numerous trackers have been proposed in recent years with considerable success. But few trackers can cope with all scenarios without failures. It is very difficult to design a tracker robust enough to keep off tracking failure. As failure is inevitable, we propose a framework to correct tracker, verify failure, predict object position and re-detect object. The original model of the first frame is...
Dual parallel mechanism as a novel accurate positioning device with large workspace is promising in the field of macro/micro manipulator. To construct spatial dual parallel mechanisms for given tasks, a mechanics definition and a systematic procedure for the synthesis of the overconstrained dual parallel mechanisms based on the screw theory are presented. As examples, the synthesis procedures of 3-DOF...
