AI总结:

本文提出了实例性能差异(IPD)指标,通过配对真实与合成图像实例并评估感知算法性能相似度,度量机器人感知任务的虚实迁移差距,助力构建逼真合成数据集并提升真实世界机器人应用的稳健迁移能力。

摘要:

在本文中,我们引入了实例性能差异(IPD)的概念,这是一种旨在度量机器人感知任务在处理真实图像与合成图像时所经历的差距的指标。通过将图像中的合成实例与真实实例配对,并利用感知算法评估它们的性能相似度,IPD提供了一种与真实世界应用需求紧密契合的针对性指标。我们通过月球地形图像中的岩石检测任务解释并演示了该指标,突出了IPD在识别最逼真图像合成方法方面的有效性。因此,该指标在创建合成图像数据集方面发挥了重要作用,使得这些数据集在感知任务中的表现能够媲美真实世界照片。这反过来又支持了感知算法在真实世界机器人应用中实现稳健的虚实迁移。

英文摘要:

In this contribution, we introduce the concept of Instance Performance Difference (IPD), a metric designed to measure the gap in performance that a robotics perception task experiences when working with real vs. synthetic pictures. By pairing synthetic and real instances in the pictures and evaluating their performance similarity using perception algorithms, IPD provides a targeted metric that closely aligns with the needs of real-world applications. We explain and demonstrate this metric through a rock detection task in lunar terrain images, highlighting the IPD's effectiveness in identifying the most realistic image synthesis method. The metric is thus instrumental in creating synthetic image datasets that perform in perception tasks like real-world photo counterparts. In turn, this supports robust sim-to-real transfer for perception algorithms in real-world robotics applications.
