IMAQ Correct Calibrated Image VI

Owning Palette: CalibrationInstalled With: NI Vision Development Module

Corrects a calibrated image by applying a calibration to create a spatially correct image.

Examples

IMAQ Correct Calibrated Image

Color Replace Value is the value used to replace pixels in a corrected color image that were not part of the original image.

cgenclasstagrefflat.gif

Image Src is a reference to the source image.

cgenclasstagrefflat.gif

Image Dst is a reference to the destination image.

ccclst.gif

ROI Descriptor is the ROI to be corrected.

c1di32.gif

Global Rectangle contains the coordinates of the bounding rectangle.

c1dcclst.gif

Contours are each of the individual shapes that define an ROI.

cenum.gif

ID refers to whether the contour is the external or internal edge of an ROI.

cu32.gif

Type is the shape type of the contour.

c1di32.gif

Coordinates indicates the relative position of the contour.

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.

cbool.gif

status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.

ci32.gif

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

cstr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

csgl.gif

Replace Value is the value that the VI uses to fill pixels in the corrected image that the VI could not correct in Image Src. The default is 0.

cu32.gif

Interpolation Type specifies the interpolation method used to obtain the corrected image. The default is Zero Order. The following options are valid:

Zero Order (0)

Rounds to the nearest integral pixel location

Bi-Linear (1)

Uses linear interpolation in both the x- and y-directions to compute the pixel location

Quadratic (2)

Uses the quadratic formula to compute the pixel location

Cubic Spline (3)

Uses cubic splines to compute the pixel location

Corrected Image is the reference to the corrected destination (output) image. If the Image Dst is connected, then Corrected Image is the same as Image Dst. Otherwise, Corrected Image refers to the image referenced by Image Src.

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.

ibool.gif

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

ii32.gif

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

istr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
