无影投影仪是一种投影映射系统，其中阴影（更具体地说，本影）不会影响投影结果。典型的阴影去除技术使用多重重叠投影系统。在本文中，我们提出了一种单投影仪的无阴影投影方法。受到临床实践中不会在患者身体上投射阴影的手术照明系统的启发，我们应用了一种特殊的光学系统，该系统由有序定位的垂直镜子组成。该光学系统作为大光圈透镜工作，不可能阻挡诸如手之类的小物体的所有投射光线。因此，仅产生半影，从而产生无阴影投影。
Shadowless Projector is projection mapping system in which a shadow (more specifically, umbra) does not suffer the projected result. A typical shadow removal technique used a multiple overlapping projection system. In this paper, we propose a shadow-less projection method with single projector. Inspired by a surgical light system that does not cast shadows on patients' bodies in clinical practice, we apply a special optical system that consists of methodically positioned vertical mirrors. This optical system works as a large aperture lens, it is impossible to block all projected ray by a small object such as a hand. Consequently, only penumbra is caused, which leads to a shadow-less projection.
