Tracking projection mosaicing by synchronized high-speed optical axis control
Masashi Nitta, Tomohiro Sueishi, Masatoshi Ishikawa · 2018
Projectors, as information display devices, have improved substantially and to achieve both the wide range and high resolution is desired for the dynamic human gaze. However, a fixed projector has a trade-off between the angle of projection and a resolution with limited pixels. Conventional methods with dynamic optical axis control lack the potential speed of the devices. We propose a tracking projection mosaicing with a high-speed projector and a high-speed optical axis controller for a randomly moving position, such as the gaze. We also propose a synchronization strategy by queuing and alternating operations to reduce motion-based artifacts, which realize a high-quality static image projection during the dynamic optical axis control. We have experimentally validated the geometric and temporal consistency of the proposed synchronization method and have attempted a demonstration of the tracking projection mosaicing for the dynamically moving bright spot of a laser pointer.
