摘要

在典型的机器人辅助训练课程中,患者需要在机器人的帮助下执行任务,同时接收2D显示器上的反馈。这种类型的三维任务需要采用立体视觉来实现正确的视觉-运动-本体感觉对齐。立体视术常引起恶心和疲劳等副作用,并可能以不明确的方式影响患者大脑的恢复和皮层重组过程。因此,机器人辅助的神经康复治疗最好在包含真实物体的真实3D环境中工作,而不是使用虚拟现实。在本文中,我们提出了一个机器人辅助神经康复场景的新系统,该系统允许患者通过操纵真实的、通用的3D物体来执行治疗。该系统基于一种新的识别和跟踪通用物体的算法,该算法有效地利用了微软Kinect传感器。为了测试跟踪算法的鲁棒性、准确性和速度以及集成系统的可行性,我们讨论了几个实验的结果。

A new Kinect-based guidance mode for upper limb robot-aided neurorehabilitation
During typical robot-assisted training sessions, patients are required to execute tasks with the assistance of a robot while receiving feedback on a 2D display. Three-dimensional tasks of this sort require the adoption of stereoscopy to achieve correct visuo-motor-proprioceptive alignment. Stereoscopy often causes side-effects as sickness and tiredness, and it may affect the processes of recovery and cortical reorganization of the patients' brain in an unclear way. It follows that it is preferrable for a robot-assisted neurorehabilitation therapy to work in a real 3D setup containing real objects rather than using virtual reality. In this paper, we propose a new system for robot-assisted neurorehabilitation scenarios which allows patients to execute therapy by manipulating real, generic 3D objects. The proposed system is based on a new algorithm for identification and tracking of generic objects which makes efficient use of a Microsoft Kinect sensor. We discuss the results of several experiments conducted in order to test robustness, accuracy and speed of the tracking algorithm and the feasibility of the integrated system.
