论文摘要
复古反射标记可以在挑战性的视觉环境中显着帮助摄影测量任务。已证明它们是ITER中远程处理的姿势估计的关键推动者。但是，ITER环境的严格要求以前明显限制了此类元素的设计并限制了其性能。在这项工作中，我们根据猫的眼睛原理确定了几种复古反射器设计，这些设计适用于ITER USECASE，并提出了一种优化其性能的方法。我们通过更改曲率半径和距离向反射表面的距离来规避一些环境限制。我们建模，制造和测试一个满足所有应用程序要求的标记，同时在目标工作范围内的先前解决方案中获得了约100％的性能增长。
Retro reflective markers can remarkably aid photogrammetry tasks in challenging visual environments. They have been demonstrated to be key enablers of pose estimation for remote handling in ITER. However, the strict requirements of the ITER environment have previously markedly constrained the design of such elements and limited their performance. In this work, we identify several retro reflector designs based on the cat's eye principle that are applicable to the ITER usecase and propose a methodology for optimizing their performance. We circumvent some of the environmental constraints by changing the curvature radius and distance to the reflective surface. We model, manufacture and test a marker that fulfils all the application requirements while achieving a gain of around 100\% in performance over the previous solution in the targeted working range.
