PROJECTION APPARATUS AND IMAGE CALIBRATION METHOD THEREOF |
| 摘要 |
A projection apparatus and an image calibration method thereof are provided. The image calibration method of the projection apparatus includes: transmitting N optical pulse signals to N calibration reference points on a projection plane respectively, wherein N is greater than or equal to 2; receiving N reflected optical pulse signals that are generated by reflecting the optical pulse signals; and respectively calculating time intervals between pulse waves of the optical pulse signals and the corresponding reflected optical pulse signals to obtain N time differences, thereby performing an image calibration. |

1. An image calibration method for a projection apparatus adapted to generate an image on a projection plane, the image calibration method comprising:
respectively transmitting N optical pulse signals to N calibration reference points on the projection plane, wherein N is greater than or equal to 2; receiving N reflected optical pulse signals generated by reflecting the optical pulse signals; respectively calculating time intervals between pulse waves of the optical pulse signals and the corresponding reflected optical pulse signals to obtain N time differences; and performing an image calibration based on the time differences. |
