摘要:

自主性是机器人手术研究的前沿,其目的是提高未来手术过程的质量。自主性的一个基本要求是通过视觉传感器实现先进的感知能力。在本文中,我们提出了一种新的校准技术与达芬奇机器人的手术场景。摄像机和机器人的校准对于工具的精确定位是必要的,以便模仿高性能的外科医生。我们的校准技术是为RGB-D相机量身定制的。对手术相关用例进行的不同测试证明,我们在外科尺寸设置上显著提高了类似器械的最新解决方案的精度和准确度。此外,我们的校准方法可以很容易地扩展到标准手术内窥镜,以促进其在实际手术场景中的使用。

英文摘要:

Autonomy is the frontier of research in robotic surgery and its aim is to improve the quality of surgical procedures in the next future. One fundamental requirement for autonomy is advanced perception capability through vision sensors. In this paper, we propose a novel calibration technique for a surgical scenario with da Vinci robot. Calibration of the camera and the robot is necessary for precise positioning of the tools in order to emulate the high performance surgeons. Our calibration technique is tailored for RGB-D camera. Different tests performed on relevant use cases for surgery prove that we significantly improve precision and accuracy with respect to the state of the art solutions for similar devices on a surgical-size setup. Moreover, our calibration method can be easily extended to standard surgical endoscope to prompt its use in real surgical scenario.
