11Peak Mirror; 12Absolute Coordinates; 13High Speed Mode - Photon Focus Python MV0-D1280-O01-3D06-288-G2 User Manual

11.5.11 Peak Mirror
The property Peak_Mirror flips the peak coordinates vertically by applying the formula
Peak_3DH-p-1, where Peak_3DH=height of scan area and p=detected laser position.
Depending on the geometrical setup of the camera and the lasers, a bigger object height may
be indicated by either a smaller or larger position. The PeakMirror property can be set to
obtain the same orientation every time.
11.5.12 Absolute Coordinates
The 3D coordinates are given relative to the start of the 3D ROI as a default.
When the property Peak0_EnAbsCoordinate is set to True then the 3D coordinates are given
relative to the first row of the sensor. This is useful if the 3D-ROI is not kept constant.
Example: Peak0_EnAbsCoordinate = True, 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.
MirrorPeak and absolute coordinates
IfPeak0_Mirror =True and Peak0_EnAbsCoordinate = True then the formula to calculate the 3D
coordinate is:
c' = MAX_H - Peak[i]_3DY - c - 1,
where c is the original (relative) coordinate without mirroring. MAX_H depends on the camera
sensor.
The resulting coordinates are then relative to the last row of the sensor.
11.5.13 High speed mode
The High Speed Mode provides higher scanning speed at the cost of reduced data accuracy (see
also Section 10.5 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
