摘要:

我们提出了一个通用的自监督学习方法的空间感知任务,如估计一个物体相对于机器人的姿态,从板载传感器读数。该模型从训练片段中学习,依赖于:连续状态估计,可能不准确并受里程漂移影响;以及检测器,偶尔提供关于目标姿势的监督。我们在三个不同的具体场景中展示了一般方法:一个模拟的机器人手臂,视觉上估计感兴趣的对象的姿态;一个小的差分驱动机器人使用7个红外传感器来定位附近的墙壁;一个全向移动机器人,定位自己在环境中从相机图像。定量结果表明,该方法在所有三种情况下都能很好地工作,并且明确地考虑不确定性会产生统计上显着的性能改善。

英文摘要:

We propose a general self-supervised learning approach for spatial perception tasks, such as estimating the pose of an object relative to the robot, from onboard sensor readings. The model is learned from training episodes, by relying on: a continuous state estimate, possibly inaccurate and affected by odometry drift; and a detector, that sporadically provides supervision about the target pose. We demonstrate the general approach in three different concrete scenarios: a simulated robot arm that visually estimates the pose of an object of interest; a small differential drive robot using 7 infrared sensors to localize a nearby wall; an omnidirectional mobile robot that localizes itself in an environment from camera images. Quantitative results show that the approach works well in all three scenarios, and that explicitly accounting for uncertainty yields statistically significant performance improvements.
