Dynamic projection mapping for moving objects has attracted much attention in recent years. However, conventional approaches have faced some issues, such as the target objects being limited to the moving speed of the objects, the limitation of the narrow depth-of-field optics, and the planar shape objects. This work proposed an adaptive three-dimensional projection prototype, and it could project an always in-focus image on a non-planar object based on liquid lens optics. The location of the non-planar object could be detected, and the mapped projection contents calculated; as a result, a stable “printed” projection mapping should be viewed on a moving object.

具有变焦镜头和视觉反馈的非平面物体的动态投影映射

近年来，运动物体的动态投影映射引起了广泛关注。然而，传统方法面临一些问题，例如目标物体受到物体移动速度的限制、窄景深光学器件的限制以及平面形状物体。这项工作提出了一种自适应三维投影原型，它可以基于液体透镜光学在非平面物体上投影始终对焦的图像。检测非平面物体的位置，并计算映射的投影内容；因此，应该在移动物体上看到稳定的“打印”投影映射。
