Tracking projection mosaicing by synchronized high-speed optical axis control

Abstract

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.
