Micro aerial vehicles equipped with high-resolution cameras can be used to create aerial reconstructions of an area of interest. In that context automatic flight path planning and autonomous flying is often applied but so far cannot fully replace the human in the loop, supervising the flight on-site to assure that there are no collisions with obstacles. Unfortunately, this workflow yields several issues, such as the need to mentally transfer the aerial vehicles position between 2D map positions and the physical environment, and the complicated depth perception of objects flying in the distance. Augmented Reality can address these issues by bringing the flight planning process on-site and visualizing the spatial relationship between the planned or current positions of the vehicle and the physical environment. In this paper, we present Augmented Reality supported navigation and flight planning of micro aerial vehicles by augmenting the users view with relevant information for flight planning and live feedback for flight supervision. Furthermore, we introduce additional depth hints supporting the user in understanding the spatial relationship of virtual waypoints in the physical world and investigate the effect of these visualization techniques on the spatial understanding.
配备高分辨率相机的微型飞行器可用于创建感兴趣区域的空中重建。在这种情况下,通常会应用自动飞行路径规划和自主飞行,但到目前为止,它还不能完全取代人工,需要人工在现场监督飞行,以确保不会与障碍物发生碰撞。不幸的是,这种工作流程存在几个问题,例如需要在 2D 地图位置和物理环境之间在心理上转换飞行器的位置,以及对远处飞行物体的复杂深度感知。通过将飞行规划过程带到现场,并可视化车辆的计划或当前位置与物理环境之间的空间关系,增强现实可以解决这些问题。在本文中,我们通过使用相关信息来增强用户的视图,为飞行规划提供支持,并为飞行监督提供实时反馈,从而展示了增强现实支持的微型飞行器的导航和飞行规划。此外,我们还引入了其他深度提示,以帮助用户理解虚拟航点在物理世界中的空间关系,并研究这些可视化技术对空间理解的影响。
