摘要： Disclosed herein are an image matting apparatus using multiple cameras and a method of generating alpha maps. The apparatus includes a multi-camera unit, a depth estimation unit, an alpha map estimation unit, and an image matting unit. The multi-camera unit acquires a main image generated when a main camera captures an object at a specific camera angle, and acquires a plurality of sub-images generated when a sub-camera captures the object at different camera angles. The depth estimation unit estimates a depth value, corresponding to a distance between the main camera and the object, for each cluster. The alpha map estimation unit estimates an alpha map of the main image using the depth value estimated by the depth estimation unit. The image matting unit extracts a foreground from the main image using the alpha map, and performs image matting using the extracted foreground.

摘要： Provided are a geometric calibration apparatus for correcting image distortions of a curved screen, and a calibration control system and method using the same. In the calibration control system for correcting the image distortions of the curved screen, a high resolution camera including a pan-and-tilt controller is installed at a center portion of a front direction of a hemispherical screen in order to well correct the distortion of the images projected from multi-projectors to a hemispherical screen. The calibration control system compares a partially photographed image with a reference image to generate a new coordinate map. Therefore, an offset between unit images projected on the hemispherical screen is removed to efficiently display an extra large image.
