Automated camera flat fielding and alignment |
| 摘要 |
In an example, a method for automated camera flat fielding and alignment may include determining a magnification of a camera relative to a first camera axis that is generally parallel to a first print media axis by evaluating first and second magnifications between transitions from a first color to a second color on a setup plot. The method may further include determining, by a processor, a rotation of the camera relative to the first camera axis such that the first magnification is approximately equal to the second magnification. |

1. A method for automated camera flat fielding and alignment, the method comprising:
determining a magnification of a camera relative to a first camera axis that is generally parallel to a first print media axis by evaluating first and second magnifications between transitions from a first color to a second color on a setup plot; and determining, by a processor, a rotation of the camera relative to the first camera axis such that the first magnification is approximately equal to the second magnification. |
