CalibrateImage

Associates a calibration with an image.CalibrateImage associates a Calib data structure with an Image data structure, to create a new Image data structure. The resulting data structure can be referenced by other vision tool functions, in order to display their results in the world coordinates defined by the referenced calibration.

For example, a sensor is calibrated using a Calibrate function. Next, a CalibrateImage function is inserted, with the Calib parameter set as Cell References to the recently created Calib structure of the Calibrate function. Then, another vision tool, such as DetectBlobs, sets its Image parameter as a cell reference to the CalibrateImage data structure, causing the DetectBlobs coordinate results in the world coordinates of the calibrated image.

Note: The output of any vision tool that reports in real-world coordinates cannot be used as a fixture or region input to another vision tool.

CalibrateImage Inputs

Parameters Description

Image

This argument must reference a spreadsheet cell that contains a valid Image data structure.
This parameter must reference a spreadsheet cell that contains an Image data structure; by default, this parameter references A0, the cell containing the Image data structure returned by AcquireImage function. This parameter can also reference other Image data structures, such as those returned by the Vision Tool Image Functions or Coordinate Transforms Functions.

Calib

This argument must reference a spreadsheet cell that contains a valid Calib data structure.

CalibrateImage Outputs

Returns

An Image data structure containing the processed image, or #ERR if any of the input parameters are invalid.
