SYSTEM FOR PERFORMING DISTORTION CORRECTION AND CALIBRATION USING PATTERN PROJECTION, AND METHOD USING THE SAME |
摘要 |
Disclosed are a system and method for performing distortion correction and calibration using a pattern projected by a projector. The system for performing distortion correction and calibration includes a projector that projects a pattern, at least one camera that generates a photographed pattern image by photographing an image onto which the pattern is projected, and an image processing device that calculates a calibration parameter by comparing an original pattern image projected by the projector and the photographed pattern image. Thus, it is possible to obtain an accurate depth image by easily utilizing an image for the pattern projected by the projector. In addition, when obtaining the depth image, the calibration parameter for correcting image distortion according to camera lens and a calibration state of cameras may be efficiently obtained using the pattern projected by the projector. |

1. A system for performing distortion correction and calibration using pattern projection, comprising:
a projector that projects a pattern; at least one camera that generates a photographed pattern image by photographing an image onto which the pattern is projected; and an image processing device that calculates a calibration parameter by comparing an original pattern image projected by the projector and the photographed pattern image. |
