摘要:

随着3D传感变得越来越便宜,能够与人类安全合作的环境感知和视觉引导机器人手臂将变得普遍。然而,需要可靠的校准,无论是相机内部校准,还是眼到手校准,以确保整个系统正常工作。我们提出了一个框架,使用一种新颖的组合,以及证明的方法,允许快速自动校准的集成系统组成的机器人和不同数量的3D相机,通过使用标准的棋盘格校准网格。我们的方法允许在设置发生任何变化后快速进行相机到机器人的重新校准,例如当相机或机器人重新定位时。系统的模块化设计确保了所使用的传感器数量以及不同硬件选择的灵活性。该框架已被证明是工作的实际实验,以分析校准的质量与用于每个校准程序的棋盘的位置的数量。

英文摘要:

With 3D sensing becoming cheaper, environment-aware and visually-guided robot arms capable of safely working in collaboration with humans will become common. However, a reliable calibration is needed, both for camera internal calibration, as well as Eye-to-Hand calibration, to make sure the whole system functions correctly. We present a framework, using a novel combination of well proven methods, allowing a quick automatic calibration for the integration of systems consisting of the robot and a varying number of 3D cameras by using a standard checkerboard calibration grid. Our approach allows a quick camera-to-robot recalibration after any changes to the setup, for example when cameras or robot have been repositioned. Modular design of the system ensures flexibility regarding a number of sensors used as well as different hardware choices. The framework has been proven to work by practical experiments to analyze the quality of the calibration versus the number of positions of the checkerboard used for each of the calibration procedures.
