다양한홀로그래픽스테레오그램설계요소들간의상관관계를명확히하여, 특정관찰자위치에서보여지는홀로그래픽스테레오그램콘텐츠를용이하게생성할수 있는방법및 그장치가개시된다. 본발명에따르면, 특정관찰자위치에서관찰가능한홀로그래픽스테레오그램콘텐츠를획득하기위해, 컴퓨터 3D 모델의위치및 크기설정등과같은작업을직접하지않아도된다. 또한, 원통형또는구형홀로그래픽스테레오그램의상관관계가정의되어있기때문에, 이를위한제작시스템을설계하는데이용할수 있다.
Abstract:
An apparatus for providing a laparoscopic surgery simulation using computer graphics comprises multiple laparoscopic surgery tools; a manipulation part in which the multiple laparoscopic surgery tools are inserted; at least one camera taking a photograph of the laparoscopic surgery tools inserted into the manipulation part; and a computing device extracting the movement of each laparoscopic surgery tool based on the image of the laparoscopic surgery tool obtained from the camera and at least one camera and displaying the movement of each laparoscopic surgery tool in the human phantom computer graphics.
Abstract:
Provided are a holographic printer and a holographic printing method. The holographic printer according to an embodiment of the present invention comprises: an optical modulation unit for displaying a holographic fringe pattern for a certain portion of an object and diffracting an incident wave; and a filtering unit for shielding a component in the diffracted wave field outputted from the optical modulation unit to be transmitted to a certain area of a holographic recording medium. The holographic printer can partially record the holographic fringe pattern in the holographic recording medium in a hogel unit so that the more realistic hologram can be recorded. Furthermore, the holographic printer filters the diffracted wave field outputted from the holographic fringe pattern to record the holographic fringe pattern while removing the unconformable components, thereby eliminating a tiling phenomenon of the hologram.
Abstract:
PURPOSE: Multiple camera based experience contents motion recognition interaction log system is provided to judge existence of interaction of experience contents, region and coordinate by recognizing plane user interaction plane operation and depth operation. CONSTITUTION: An image acquisition module (210) acquires a red-green-blue (RGB) image from a front camera (100) and a vertical camera (100). A user object detection module (240) removes a background image from a user image and extracts a valid user object. An interaction existence judgment module (220) judges whether occurrence of interaction by a contents indication region is included in an interaction detection region. An interaction log data accumulation module (260) stores frame unit interaction information in a database.
