Projected augmented reality, also called projection mapping or video mapping, is a form of augmented reality that uses projected light to directly augment 3D surfaces, as opposed to using pass-through screens or headsets. The value of projected AR is its ability to add a layer of digital content directly onto physical objects or environments in a way that can be instantaneously viewed by multiple people, unencumbered by a screen or additional setup. Because projected AR typically involves projecting onto non-flat, textured objects (especially those that are conventionally not used as projection surfaces), the digital content needs to be mapped and aligned to precisely fit the physical scene to ensure a compelling experience. Current projected AR techniques require extensive calibration at the time of installation, which is not conducive to iteration or change, whether intentional (the scene is reconfigured) or not (the projector is bumped or settles). The workflows are undefined and fragmented, thus making it confusing and difficult for many to approach projected AR. For example, a digital artist may have the software expertise to create AR content, but could not complete an installation without experience in mounting, blending, and realigning projector(s); the converse is true for many A/V installation teams/professionals. Projection mapping has therefore been limited to high-end event productions, concerts, and films, because it requires expensive, complex tools, and skilled teams ($100K+ budgets). Lightform provides a technology that makes projected AR approachable, practical, intelligent, and robust through integrated hardware and computer-vision software. Lightform brings together and unites a currently fragmented workflow into a single cohesive process that provides users with an approachable and robust method to create and control projected AR experiences.

Lightform：投影 AR 的程序效果

投影增强现实，也称为投影映射或视频映射，是一种增强现实形式，它使用投影光直接增强 3D 表面，而不是使用直通屏幕或耳机。投影 AR 的价值在于它能够以多人即时观看的方式将数字内容直接添加到物理对象或环境中，不受屏幕或其他设置的影响。由于投影 AR 通常涉及投影到非平面、有纹理的对象（尤其是那些通常不用作投影表面的对象），因此需要映射和对齐数字内容以精确适应物理场景，以确保引人入胜的体验。当前的投影 AR 技术需要在安装时进行大量校准，这不利于迭代或更改，无论是有意的（重新配置场景）还是无意的（投影仪颠簸或安顿下来）。工作流程未定义且支离破碎，从而使许多人难以接近投影 AR。例如，数字艺术家可能拥有创建 AR 内容的软件专业知识，但如果没有安装、混合和重新调整投影仪的经验，则无法完成安装；对于许多 A/V 安装团队/专业人士来说，情况正好相反。因此，投影映射仅限于高端活动制作、音乐会和电影，因为它需要昂贵、复杂的工具和熟练的团队（10 万美元以上的预算）。Lightform 提供了一种技术，使投影 AR 平易近人、实用、智能、通过集成的硬件和计算机视觉软件实现强大的功能。Lightform 将当前分散的工作流程整合并整合到一个单一的有凝聚力的过程中，为用户提供一种平易近人且强大的方法来创建和控制投影 AR 体验。
