Abstract:
After calibration of the projector, the control circuit obtains a first position-data indicating the position of a feature point in the screen and a second position-data indicating the position of a feature point in a test image projected onto the screen. After acquisition of the first position-data and the second position-data, the control circuit obtains a third position-data indicating the position of a feature point in the screen and a fourth position-data indicating the position of a feature point in the test image projected onto the screen. Based on a difference between the first position-data and the third position-data, the control circuit corrects the position of a feature point in the test image contained in the fourth position-data to create a fifth position-data. Based on a difference between the second position-data and the fifth position-data, the control circuit recalibrates the projector.

Claim (Index 1):
A calibration device comprising:\n a controller for calibrating at least one projection display device that projects an image on a projection plane, wherein, the controller causes an imaging device to capture an image of the projection plane, the controller obtaining from the captured image a first position-data that indicating a set of positions of plural feature points in the projection plane, the controller causes the at least one projection display device to project a test image on the projection plane and then causes the imaging device to capture an image of the test image, the controller obtaining from the captured image a second position-data that indicating a set of positions of plural feature points in the test image, and then, the controller causes the imaging device to capture an image of the projection plane, the controller obtaining from the captured image a third position-data that indicating a set of positions of the feature points in the projection plane, the controller causes the at least one projection display device to project the test image on the projection plane and then causes the imaging device to capture an image of the test image, the controller obtaining from the captured image a fourth position-data that indicating a set of positions of the feature points in the test image, based on a difference between the first position-data and the third position-data, the controller obtains a first deviation-data that indicates a deviation in a relative position between the imaging device and the projection plane, and based on the first deviation-data, the controller corrects the set of positions of the feature points in the test image contained in the fourth position-data to create a fifth position-data, and based on a difference between the second position-data and the fifth position-data, the controller obtains a second deviation-data that indicates a deviation in a relative position between the at least one projection display device and the projection plane, and based on the second deviation-data, the controller calibrates the at least one projection display device.
