Get Rectified Image from Stereo (G Dataflow)

Last Modified: June 25, 2019

Returns the rectified image from the left or the right camera.

connector_pane_image
datatype_icon

interpolation type

Interpolation method used to generate the output image.

Name Value Description
zero order 0

(Default) 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.

datatype_icon

binocular stereo session in

Reference to the binocular stereo vision session on which this node operates.

datatype_icon

image src

Reference to the input image from either the left or right camera in the stereo system.

datatype_icon

image dst

Reference to the image that will contain the rectified image after the node executes.

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

reference coordinate system

Camera from which the image src is acquired.

Name Description
left camera The image is acquired from the left camera.
right camera The image is acquired from the right camera.
datatype_icon

binocular stereo session out

Reference to the stereo vision session on which this node operates.

datatype_icon

image dst out

Reference to the rectified image.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
