Task

Define a set of constraints for the generation of a matrix of targets.

Description

The method SetTargetMatrixInPlane allows you to define a set of constraints for the generation of a matrix of targets contained in a selected working plane.

The rotation of the targets is randomly selected from a range.

To define a specific value for a constraint, set the minimum and the maximum to the same value.

The following is an example of matrix generation of targets:

Targets generation order, according to the selected working plane

Targets generation order, according to the selected working plane and the value of i_stMatrixElementsStep

Interface

Input	Data type	Description
i_udiNumberOfRows	UDINT	Number of rows of the matrix of targets.
i_udiNumberOfColumns	UDINT	Number of columns of the matrix of targets.
i_etPlane	ET_WorkingPlane	Used to select a working plane (for example, XY, XZ, YZ). The value of this input cannot be ROB.ET_WorkingPlane.None. While a specific working plane is selected, any generated pose describes a position contained in the plane (the position along the third 3D axis is set to 0) and a rotation about a vector normal to the plane.
i_stMatrixOriginPosition	PDL.ST_Vector3D	Position of the matrix origin. The targets are generated starting from this position. It must be contained in the selected working plane.
i_stMatrixElementStep	PDL.ST_Vector3D	Position steps along the X, Y and Z axes, used for the generation of the positions in the matrix. The value provided here must be compliant with the selected working plane.
i_lrMinRotation	LREAL	Minimum rotation angle used to generate the pose of a target.
i_lrMaxRotation	LREAL	Maximum rotation angle used to generate the pose of a target.
i_etOrientationConvention	ROB.ET_OrientationConvention	Convention for the rotation angles of the orientation.
i_alrTargetTypeProbabilityList	ARRAY [1...Gc_uiMaxNumberOfTargetTypes] OF LREAL	Every index of this array is linked to a specific target type and every element contains a value that affects the probability that a target with a certain target type is randomly generated. The probability of each target type is evaluated as the ratio between the value assigned to each element of the array and the total sum of the listed values. Example: A value in the field [1] of the array is linked to the generation of targets of type 1, field [2] is linked to type 2, and so on.

Output	Data type	Description

q_sMsg	STRING[80]	Event-triggered message that gives more detailed information on the diagnostic state.
