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.

小型企业创新研究(SBIR)第一阶段项目的更广泛影响/商业潜力将是创造工具，使一种名为投影地图的新交互媒介民主化。投影地图使用视频投影仪将数字内容(图像、动画或视频)覆盖到3D实物上，允许观众以一种全新的方式体验数字体验并与之互动。这些互动展示将为需要动态3D演示以提供信息、教育、广告或娱乐的广泛行业增加价值。应用包括在博物馆或学校的教育体验，康复和可视化的医疗应用，新的培训和模拟展示，以及在广告和娱乐中的广泛应用。例如，零售端的过道陈列可以通过直接在实体产品上或周围投射光线来展示产品功能，从而更容易吸引客户。或者，博物馆里的互动立体图可以让参观者通过身临其境的视觉体验来学习历史。该项目将把投影地图从高预算，利基市场，到低预算，主流市场。成本的降低将通过减少设计、设置和校准要求的技术进步来实现，这反过来又将提高技术能力和内容创作。这个小型企业创新研究(SBIR)第一阶段项目建议开发一个用于创作投影地图内容的新型软件和硬件系统。拟议的系统将极大地简化目前复杂的内容创作过程，并将实现将数字内容与物理环境相融合的全新的被动和互动体验。该系统由内容创作软件套件和能够进行高分辨率3D扫描的投影仪深度相机硬件单元组成。研究目标涉及以下领域的新软件算法：1)投影仪-相机系统的自动校准；2)3D对象的优化结构光扫描；3)响应物理模型的移动自动、精确地重新对准和配准系统；4)用于创建被动和交互式投影映射体验的直观创作工具。
