Correct Calibrated Image (G Dataflow)

Last Modified: June 25, 2019

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

datatype_icon

U32 color replace value

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

datatype_icon

image src

Reference to the source image.

datatype_icon

image dst

Reference to the destination image.

datatype_icon

ROI descriptor

ROI to be corrected.

datatype_icon

global rectangle

Coordinates of the bounding rectangle.

datatype_icon

contours

Individual shapes that define an ROI.

datatype_icon

ID

Object specifying if contour is the external or internal edge of an ROI.

datatype_icon

Type

Shape type of the contour.

datatype_icon

Coordinates

Relative position of the contour.

datatype_icon

replace value

Value the node uses to fill pixels in the corrected image that the node could not correct in image.

Default: 0

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

interpolation type

Interpolation method used to obtain the corrected image.

Name Value Description
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

Default: zero order

datatype_icon

image dst out

Reference to the corrected destination image.

If image dst is connected, then image dst out is the same as image dst. Otherwise, image dst out refers to the image referenced by image.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
