NeRF 方法提升航天器姿态估计和三维重建能力

研究人员开发了新的基于神经辐射场(NeRF)的方法,以提高从图像中进行航天器姿态估计和三维重建的性能。一种方法利用基于 NeRF 的增强技术,用更少的图像训练姿态估计器,克服了传统基于 CAD 的训练的局限性。另一种方法通过引入每张图像的外观嵌入和姿态校正来增强 NeRF,使其在重建过程中对光照变化和不准确的姿态数据更加鲁棒。 AI

影响 新的基于 NeRF 的技术有望为太空任务提供更鲁棒、数据效率更高的航天器姿态估计和三维重建。

    通过 NeRF 增强实现航天器姿态估计器的无 CAD 学习

    Spacecraft pose estimation networks require tens of thousands of CAD-rendered images to be trained. This reliance on synthetic CAD data (i) limits applicability to targets with reliable geometry prior, excluding uncooperative or poorly documented spacecraft, and (ii) causes poor …

    基于NeRF的航天器近距离单目图像重建,应对光照变化和姿态不确定性

    Autonomous rendezvous and proximity operations around uncooperative, unknown spacecraft are critical for active debris removal and on-orbit servicing missions. A key component of such operations is the offline reconstruction of a 3D model of the target from a set of 2D images. Th…
