Assigns coordinate system information to a calibration template image.
IMAQ Set Calibration Axis Info
Assigns coordinate system information to a calibration template image. Use this instance with a point distance calibration, when the image is not distorted, and the origin of the calibration axis is within the image.
Supported Image Types

Calibration Template Image In is a reference to the template image to use for calibrating your system. |

Calibration Axis Info defines a Reference Coordinate System for the real-world coordinates.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

Calibration Template Image Out is the reference to the output image. |

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

IMAQ Set Calibration Axis Info - Point
Assigns coordinate system information to a calibration template image. Use this instance when the image is calibrated with a perspective, distortion model, or microplanes, and the origin of the calibration axis is within the image.

Note This method is recommended over setting the axis using an angle because it is usually more accurate to specify a point on the X-axis than the angle of the calibration axis, especially if the image is distorted. |
