摘要:

当前的端到端抓取规划方法提出了在不同的对象集合上获得高抓取成功率的秒级的抓取,但是通常通过将工作空间约束为顶部抓取。在这项工作中,我们提出了一种方法,允许端到端的顶部抓取规划方法,以生成完整的六个自由度的把握使用一个单一的RGB-D视图作为输入。这是通过估计要抓取的物体的完整形状,然后模拟物体的不同视点,将模拟的视点传递到端到端抓取生成方法,并最终执行整体最佳抓取来实现的。该方法通过比较最先进的全卷积抓取质量CNN在模拟和真实相机图像上生成的429次抓取,在Franka Panda上进行了实验验证。结果表明,在统计学上显着的改善,在把握成功率方面,使用模拟图像时,在真实的相机图像,特别是当真实的相机的角度。代码和视频可在https://irobotics.aalto.fi/beyond-top-grasps-through-scene-completion/上获得。

英文摘要:

Current end-to-end grasp planning methods propose grasps in the order of seconds that attain high grasp success rates on a diverse set of objects, but often by constraining the workspace to top-grasps. In this work, we present a method that allows end-to-end top-grasp planning methods to generate full six-degree-of-freedom grasps using a single RGB-D view as input. This is achieved by estimating the complete shape of the object to be grasped, then simulating different viewpoints of the object, passing the simulated viewpoints to an end-to-end grasp generation method, and finally executing the overall best grasp. The method was experimentally validated on a Franka Emika Panda by comparing 429 grasps generated by the state-of-the-art Fully Convolutional Grasp Quality CNN, both on simulated and real camera images. The results show statistically significant improvements in terms of grasp success rate when using simulated images over real camera images, especially when the real camera viewpoint is angled.
