Abstract

We present a focal surface projection to solve the narrow depth-of-field problem in projection mapping applications. We apply a phase-only spatial light modulator to realize nonuniform focusing distances, whereby the projected contents appear focused on a surface with considerable depth variations. The feasibility of the proposed technique was validated through a physical experiment.

焦面投影:使用纯相位空间光调制器来扩展投影仪的景深

为了解决投影映射应用中景深较窄的问题，提出了一种焦面投影。我们采用纯相位空间光调制器来实现非均匀聚焦距离，从而使投影内容看起来聚焦在具有相当深度变化的表面上。通过物理实验验证了该技术的可行性。
