The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project will be the creation of tools that democratize a new interactive medium called projection mapping. Projection mapping uses video projectors to overlay digital content (images, animations or video) onto 3D physical objects, allowing viewers to experience and interact with digital experiences in an entirely new way. These interactive displays will add value to a wide range of industries where dynamic, 3D presentations are needed to inform, educate, advertise or entertain. Applications include educational experiences at museums or schools, healthcare applications for rehabilitation and visualization, new training and simulation displays, as well as broad uses in advertising and entertainment. For example, a retail end aisle display could more easily attract customers by demonstrating product features with projected light directly on or around the physical product. Alternatively, an interactive diorama in a museum could allow visitors to learn history through an immersive visual experience. This project will bring projection mapping from high budget, niche markets into low budget, mainstream markets. Cost reductions will be realized through technological advances that decrease design, setup and calibration requirements, which in turn will advance technological capabilities and content authoring.This Small Business Innovation Research (SBIR) Phase I project proposes to develop a novel software and hardware system for authoring projection mapping content. The proposed system will greatly simplify a currently complex content authoring process, and will enable entirely new passive and interactive experiences which fuse digital content with the physical environment. The system is comprised of a content authoring software suite and a projector-depth camera hardware unit capable of high-resolution 3D scanning. Research objectives entail novel software algorithms in the areas of 1) automatic calibration of projector-camera systems, 2) optimized structured light scanning of 3D objects, 3) automatic, precise re-alignment and registration of the system in response to movement of the physical model, 4) intuitive authoring tools for creating passive and interactive projection mapping experiences.

这个小企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力将是创造一种工具，使一种称为投影映射的新型互动媒体民主化。投影映射使用视频投影仪将数字内容（图像、动画或视频）覆盖到3D物理对象上，让观众以一种全新的方式体验和互动数字体验。这些交互式显示器将为许多需要动态3D演示来提供信息、教育、广告或娱乐的行业增加价值。应用包括博物馆或学校的教育体验，康复和可视化的医疗保健应用，新的培训和模拟显示，以及广告和娱乐中的广泛应用。例如，通过直接在实体产品上或周围投射灯光来展示产品特征，可以更容易地吸引顾客。另外，博物馆中的交互式立体模型可以让游客通过身临其境的视觉体验来了解历史。这个项目将把投影映射从高预算、小众市场带入低预算、主流市场。通过减少设计、设置和校准需求的技术进步，将实现成本的降低，这反过来又将提高技术能力和内容创作。这个小企业创新研究（SBIR）第一阶段项目建议开发一种新的软件和硬件系统来创作投影映射内容。拟议中的系统将大大简化目前复杂的内容创作过程，并将实现全新的被动和交互式体验，将数字内容与物理环境融合在一起。该系统由一个内容创作软件套件和一个能够进行高分辨率3D扫描的投影仪深度相机硬件单元组成。研究目标包括以下领域的新软件算法：1)投影仪-摄像机系统的自动校准；2)优化3D物体的结构光扫描；3)响应物理模型的运动对系统进行自动、精确的重新对准和配准；4)用于创建被动和交互式投影映射体验的直观创作工具。
