Abstract:
The present invention relates to an interactive three-dimensional imaging device comprising an output unit which alternately outputs a right image corresponding to the right eye of a user and a left image corresponding to the left eye of the user on a screen; a stereoscopic image delivery unit which delivers the outputted right image and the left image to recognize a stereoscopic image; a retroreflector which reflects incident light in a direction of the light; and a half-mirror which is disposed between the stereoscopic image delivery unit and the retroreflector, transmits and delivers the image delivered from the stereoscopic image delivery unit, and delivers the image reflected from the retroreflector by reflecting the image. Therefore, the stereoscopic image can be recognized from the close distance so that the interaction by experiencing realistic images and touching the images by hand at the same time is possible.

홀로그래픽 프린터 및 그의 홀로그래픽 프린팅 방법이 제공된다. 본 발명의 실시예에 따른 홀로그래픽 프린터는, 물체의 특정 부분에 대한 홀로그래픽 프린지 패턴이 디스플레이되어 입사파를 회절시키는 광변조부 및 광변조부에서 출사되는 회절된 웨이브 필드 중 일부 성분을 차단하여 홀로그래픽 기록매질의 특정 영역으로 전달하는 필터링부를 포함한다. 이에 의해, 홀로그래픽 프린지 패턴을 호겔 단위로 일부분씩 홀로그래픽 기록매질에 기록할 수 있어 보다 실감적인 홀로그램 기록이 가능하고, 홀로그래픽 프린지 패턴에서 출사되는 회절된 웨이브 필드를 필터링하여 부적합한 성분들을 제거하면서 기록할 수 있게 되어 홀로그램의 타일화 현상을 없앨 수 있게 된다.
Abstract:
Provided are an apparatus for converting a two-dimensional image into a hologram image and a method thereof. The apparatus for converting a two-dimensional image into a hologram image includes a selected-image matching unit for searching an object pattern, which is the most similar to a two-dimensional image to be converted into a hologram image, for an object pattern database which stores classified object patterns; an object image extracting unit for rotating a three-dimensional object pattern according to a preset rotation angle to extract two-dimensional images at each viewing point according to an angular velocity after the two-dimensional image is restored to the three-dimensional object in a virtual space based on information about the searched object pattern by the selected-image matching unit; and a hologram generating unit for extracting information about a hogel having a three-dimensional depth in each directions based on the two-dimensional extracted image according to the rotation angle and for rearranging the extracted hogel information to generate a hologram corresponding to the two-dimensional image. As described above, the apparatus for converting a two-dimensional image into a hologram image may provide an effect of a real hologram based on a two-dimensional image, thereby allowing everyone to easily enjoy 3D images.
