Get Tracking Object Information (G Dataflow)

Last Modified: June 25, 2019

Returns information about the object being tracked.

You can also use this node to change tracking information and pass the changes to the Track Objects node.

connector_pane_image
datatype_icon

tracking session in

Reference to the object tracking session.

datatype_icon

image in

Image containing an object to track.

datatype_icon

object index

Index of the object to remove.

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

tracking session out

Reference to the object tracking session.

datatype_icon

image out

Reference to the destination image containing the object being tracked.

datatype_icon

label

Label of the object in the tracking session.

datatype_icon

position

x- and y-coordinates of the object being tracked, in pixels.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

datatype_icon

angle

Angle to rotate.

Default: 0 degrees
