CameraXYU Result

Runtime Only

Applies To

Vision Objects: Blob, Correlation, Edge, Geometric, Point, Polar

Description

Returns the CameraX, CameraY and Angle position coordinates of the found part's position in the camera
coordinate frame.

Usage

VGet Sequence.Object.CameraXYU [(result)], found, xVar, yVar, uVar

Sequence Name of a sequence or string variable containing a sequence name.

Object

Name of an object or string variable containing an object name. The object must exist in the
specified sequence.

found

Boolean variable representing whether or not the part you are looking for was found.

xVar

Real variable that will contain the X coordinate position of the part.

yVar

Real variable that will contain the Y coordinate position of the part.

uVar

Real variable that will contain the angular position (rotation) of the part with respect to the
camera coordinate system

result

Optional result number. If omitted, the result number is the CurrentResult. Used for objects
that return multiple results.

Values

found

Boolean value which is either True or False

xVar

Real number in millimeters

yVar

Real number in millimeters

uVar

Real number in degrees

Remarks

The xVar and yVar values are returned in millimeters since the Camera Coordinate Frame is calibrated in
millimeters. The uVar value is returned in degrees.

It should be noted that the CameraXYU result can only be calculated for vision sequences which have been
associated with a calibration. If no calibration has been assigned to the vision sequence then if VGet is
used to retrieve the CameraXYU result, an error will occur.

The CameraXYU result is available at runtime only.
