提出一种由无人机和LED灯带构成的LightBender系统,用于在空中照明线条图和字母,通过算法优化编队、Blender插件和SVG导入实现创作与部署,实验表明10.1毫米偏差在感知上可接受。

摘要:

本研究提出了一种变革性系统的硬件和软件架构,用于照明线条图和字母形式。这些空中照明在室内进行,并且可以动画化。硬件贡献是一架配备伺服驱动杆关节和密集可寻址LED灯带的无人机,能够实现任意方向,即LightBender。软件贡献有三方面。首先,系统实现了算法和启发式方法,用于估计渲染线条图或字母形式所需的最小LightBender数量,交错编队以减轻LightBender的下洗气流,生成Swarm Flight and Lighting (SFL)文件,并使用LightBender群执行这些文件以照明线条图和字母形式。其次,一个Blender插件使用户能够注册LightBender,创作由LightBender群表示的图形和动画,并通过一键功能部署群进行照明。第三,用户可以将SVG文件导入Blender插件或独立的LB-Author工具,直接从矢量图形照明线条图。我们展示了一项IRB批准的人体受试者研究(n=21)的结果,以评估LightBender未对准对感知照明的影响。获得的结果表明,系统最大10.1毫米的未对准在测试的照明中在感知上是可接受的,中位质量评分为8(0-10分制)。

英文摘要:

This study presents the hardware and software architecture of a transformative system for illuminating line drawings and letterforms. These mid-air illuminations are indoors and might be animated. The hardware contribution is a drone equipped with servo-actuated rod joints and a dense, addressable LED strip that enables arbitrary orientation, a LightBender. The software contributions are threefold. First, the system implements algorithms and heuristics to estimate the minimum number of LightBenders required to render a line drawing or letterform, stagger swarm formations to mitigate LightBender downwash, generate Swarm Flight and Lighting (SFL) files, and execute these files using a swarm of LightBenders to illuminate line drawings and letterforms. Second, a Blender add-on enables users to register LightBenders, author graphics and animations represented by swarms of LightBenders, and deploy the swarm for illumination through one-click functions. Third, users may import SVG files into either the Blender add-on or a standalone LB-Author tool to illuminate line drawings directly from vector graphics. We present results from an IRB-approved human subject study (n=21) to evaluate the impact of LightBender misalignment on the perceived illuminations. Obtained results demonstrate that the system's 10.1 mm maximum misalignment is perceptually acceptable across tested illuminations, with a median quality rating of 8 on a 0-10 scale.
