摘要:

本文提出了一种自监督的单目图像到深度预测框架,该框架使用端到端的光度损失进行训练,不仅可以处理6-DOF相机运动,还可以处理6-DOF移动对象实例。通过使用包括对象实例的深度和场景运动在视频序列上扭曲图像来执行自我监督。所提出的方法的一个新颖之处是使用多头注意力的Transformer网络,匹配移动对象跨时间和模型的相互作用和动态。这使得能够对每个对象实例进行准确且鲁棒的姿态估计。大多数图像到深度预测框架都假设场景是刚性的,这在很大程度上降低了它们对动态对象的性能。只有少数SOTA论文考虑了动态对象。所提出的方法优于这些方法的标准基准和暴露的动态运动对这些基准的影响。此外,所提出的图像到深度预测框架也被证明是具有竞争力的SOTA视频到深度预测框架。

英文摘要:

This paper proposes a self-supervised monocular image-to-depth prediction framework that is trained with an end-to-end photometric loss that handles not only 6-DOF camera motion but also 6-DOF moving object instances. Self-supervision is performed by warping the images across a video sequence using depth and scene motion including object instances. One novelty of the proposed method is the use of the multi-head attention of the transformer network that matches moving objects across time and models their interaction and dynamics. This enables accurate and robust pose estimation for each object instance. Most image-to-depth predication frameworks make the assumption of rigid scenes, which largely degrades their performance with respect to dynamic objects. Only a few SOTA papers have accounted for dynamic objects. The proposed method is shown to outperform these methods on standard benchmarks and the impact of the dynamic motion on these benchmarks is exposed. Furthermore, the proposed image-to-depth prediction framework is also shown to be competitive with SOTA video-to-depth prediction frameworks.
