    摘要: An automatic calibration method for a projector-camera system including a semi-transparent screen is disclosed herein. An image sequence is caused to be captured from the semi-transparent screen and through the semi-transparent screen while a calibration pattern having features is displayed and not displayed in an alternating succession on the semi-transparent screen. A temporal correlation image is created from the image sequence and a discrete binary signal. Peaks are identified in a spatial cross correlation image generated from the temporal correlation image, where a pattern of the identified peaks corresponds to a pattern of the features in the calibration pattern. The peaks are transformed to coordinates of corrected feature points. A comparison of the corrected feature points and a ground truth set of coordinates for the features is used to determine whether the projector-camera system is calibrated.
