在攀岩运动中，与他人讨论攀岩技术以掌握特定的路线，并从更有经验的攀岩者那里获得实用的建议是这项运动文化和传统的固有组成部分。空间信息，比如握把的位置，以及学习复杂的身体姿势，在这个过程中起着重要作用。在建议过程中出现的一个典型问题是，当试图描绘特定方向的知识时，例如向他人解释如何执行某种自我攀登动作时，会出现对齐效应。我们提出betaCube，一种自校准相机投影单元，具有3D跟踪和无失真投影功能。该系统可以使用增强现实技术进行真人大小的视频回放和攀岩路线创建。我们提供了一个用于自动设置移动无扭曲投影的接口，用于攀爬点的斑点检测，以及从人工攀岩壁中提取平面可追踪物的自动方法。
In rock climbing, discussing climbing techniques with others to master a specific route and getting practical advice from more experienced climbers is an inherent part of the culture and tradition of the sport. Spatial information, such as the position of holds, as well as learning complex body postures plays a major role in this process. A typical problem that occurs during advising is an alignment effect when trying to picture orientation-specific knowledge, e.g. explaining how to perform a certain self-climbed move to others. We propose betaCube, a self-calibrating camera-projection unit that features 3D tracking and distortion-free projection. The system enables a life-sized video replay and climbing route creation using augmented reality. We contribute an interface for automatic setup of mobile distortion-free projection, blob detection for climbing holds, as well as an automatic method for extracting planar trackables from artificial climbing walls.
