Recently, robotic technologies, from industrial machines to commercial entertainment products, are increasingly influential in our lives. There is continual development of robots for domestic, medical, and industrial purposes under way in corporate and university research labs. In efforts to make robots more intelligent and cognitive, robots have been developed to obtain much useful information including scene understanding and spatial relationship from a machine vision system. TRecently, robotic technologies, from industrial machines to commercial entertainment products, are increasingly influential in our lives. There is continual development of robots for domestic, medical, and industrial purposes under way in corporate and university research labs. In efforts to make robots more intelligent and cognitive, robots have been developed to obtain much useful information including scene understanding and spatial relationship from a machine vision system. Finally, we demonstrate two grasping scenarios with a dexterous arm, ADAM, where an object in front of ADAM can be grasped. This demonstration shows our robot arm can robustly and autonomously grasp a randomly rotative rigid object detected by SIFT in 3D space.
中文摘要:
本論文目的旨在發展機器人對於人臉辨識的方法以及對於物件姿態估測的演算法以利於機器人自主抓取,所提出的人臉辨識方法是利用AAM來取出人臉特徵,再利用人臉的形狀描述子來辨識人臉。並且在假設已知物件的3維幾何形狀前提下,藉由SIFT所追蹤到物件上的點以及立體視覺估測到物體的3維點雲,我們所提出的姿態估測演算法能正確地估測出物件的姿態。同時我們也建立了一個整合物件偵測、物件定位、姿態估測、軌跡規劃以及真實機器手臂的視覺導引架構,利用視覺導引機器手臂到達目標物。 最後本論文藉由一個靈巧的機器手臂亞當展示了2個抓握方案,它必須抓取它面前所能抓到的物件,此展示顯示我們的機器手臂能在3維空間中強健且自主地抓取一個任意轉動且被SIFT偵測到的物件。 |
