METHOD FOR HIGH-SPEED PRODUCTION OF HOLOGRAM VIDEO FOR THREE-DIMENSIONAL OBJECT IN STATE OF FREE MOTION ACCORDING TO CURVED HOLOGRAM-BASED ROTATIONAL-MOTION COMPENSATION METHOD ON BASIS OF CONCEPT OF ROTATION-INVARIANCE OF CURVED SURFACE HOLOGRAM

摘要

The present invention relates to a method for high-speed production of a hologram video for a three-dimensional object in a state of free motion according to a curved hologram-based rotational-motion compensation method on the basis of a concept of the rotation-invariance of a curved surface hologram, that is, a curved hologram-based rotational-motion compensation (CH-RMC) method on the basis of a concept of the rotation-invariance of a curved surface hologram in order to produce at a high speed a hologram video for a three-dimensional object in a state of free motion, wherein all rotation motions of a three-dimensional object made on every arc can be directly compensated by the rotation of local curved holograms on curved surfaces matched with the trajectories on which the object moves, and thus most hologram patterns of the three-dimensional object in rotational motion can be directly generated without any additional calculation process. Therefore, the overall calculation time of the hologram video can be greatly reduced. The present invention is highly advantageous in that the cost in time to calculate a hologram video is greatly reduced and thus a hologram for a three-dimensional object can be produced in real time.
