Abstract: Disclosed herein is a real-time dynamic non-planar projection apparatus and method, which can reduce visual errors, such as distortion of a screen image or deviation from a border area, upon projecting screen images from a projector onto the surface of a non-planar object that is moved in real time. The presented real-time dynamic non-planar projection apparatus includes a preprocessing unit for preprocessing data related to a static part of a screen image to be projected onto a non-planar surface. A real-time projection unit classifies non-planar objects in the screen image to be projected onto the non-planar surface into a rigid body and a non-rigid body using data output from the preprocessing unit, respectively renders the rigid body and the non-rigid body depending on a viewer's current viewpoint, and projects rendered results onto the non-planar surface via projection mapping.

Abstract: An interactive content control apparatus and method includes a depth information acquisition unit for acquiring an image that includes depth information by capturing a static background object and a dynamic foreground object, and for calculating depth maps based on respective depth values of the static background object and the dynamic foreground object from the image, a display unit for projecting image content including a background image and an object image on a surface of the static background object captured by the depth information acquisition unit, and an image mapping unit for recognizing the dynamic foreground object depending on the depth maps based on the depth values calculated by the depth information acquisition unit, and controlling the display unit so that an object image projected on the surface of the static background object is transferred to and projected on a surface of the dynamic foreground object.
