5.2 3D Features
5.2.14 Absolute Coordinates
The "absolute coordinates" feature is available in camera revision 2.2 and later.
The 3D coordinates are given relative to the start of the 3D ROI as a default.
When the property
Peak[i]_EnAbsCoordinate
is set to True for peak i then the 3D coordinates are
given relative to the value of the property
Peak[i]_AbsCoordinateBase
. This is useful if the
3D-ROI is not kept constant.
Example:
Peak0_EnAbsCoordinate
= True,
Peak0_AbsCoordinateBas
e = 0,
Peak0_3DY
=200: If the peak
is detected in row 50 of the ROI, the value 250 (50+Peak0_3DY) would be given as resulting 3D
coordinate.
The value of
Peak[i]_AbsCoordinateBase
must fulfill the following conditions:
(
Peak[i]_AbsCoordinateBase
<=
Peak[i]_3DY
) and (
Peak[i]_AbsCoordinateBase
+
1024 >= Peak[i]_3DY + Peak[i]_3DH ).
MirrorPeak and absolute coordinates
If
Peak[i]_Mirror
=True and
Peak[i]_EnAbsCoordinate
= True then the formula to calculate the 3D
coordinate is:
c’ = MAX_H + Peak[i]_AbsCoordinateBase - Peak[i]_3DY - c - 1,
where c is the original (relative) coordinate without mirroring. MAX_H =1024 for 3D03 and
MAX_H =2048 for 3D04. This is the same as mirroring in a ROI with Y= Peak[i]_AbsCoordinateBase
and H= MAX_H .
5.2.15 High speed mode
The High Speed Mode provides higher scanning speed at the cost of reduced data accuracy (see
also Section 5.3.2 for a list of frame rates). The average loss in data accuracy is +/- 0.5 pixel.
High speed mode is only available in 3Donly mode
High speed mode is not available in combination with Moving ROI
The High Speed feature is not available in all camera revisions (see Appendix B).
