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.
