Stealth Projection: Visually Removing Projectors from Dynamic Projection Mapping

In the present study, we propose a stealth projection method that visually removes the ProCam system in dynamic projection mapping (DPM). In recent years, DPM has been actively studied to change the appearance of moving and deforming objects by image projection. Various objects, such as an object held by the user, clothes, a human body, and a face, are projection targets, and the possibility of expressing these objects has continuously evolved. However, in order to realize this, high-speed and multiplexed special projection systems are needed, and objects are being closely enclosed by the systems. In DPM that seamlessly connects the real world and the virtual world, a complex device is an unnecessarily visually disturbing factor and should be removed in order to further exploit the potential effects of DPM. Therefore, in the present research, we propose a stealth projection method using a ProCam system that cannot be seen by combining a method that is capable of high-speed tracking with a single IR camera and all-around projection technology applying aerial image display technology.
