“…It solves the problem that the projection picture is not clear due to the limited depth of field range of the traditional projector. Moreover, Wang et al designed the interactive head-mounted display ARSlice, which uses a projector to project CT image sections onto the headmounted display 15 . Users can see clear CT section images when moving within 0.5-2 meters, but this system is designed to project 2D information onto 2D planar objects moving in a 3D space.…”

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.

Dynamic projection mapping is an interactive display technology, which is capable with multiplayers with naked eyes for augmented reality. However, the fixed and shallow depth-of-field of the projector optics limits its potential applications. In this work, a high-speed projection mapping method with a dynamic focal tracking technology based on a variable focus lens will be illustrated. The proposed system included a high-speed variable focus lens, a high-speed camera, and a high- speed projector, so that the depth and rotation information would be detected and then served as feedback to correct the focal length and update the projection information in real time. As a result, the information would be well-focused projected even on a 3D dynamic moving object. The response speed of the high-speed prototype could reach around 5 ms, and the dynamic projection range covered from 0.5 to 2.0 m.
