Saving the images
The acquired
Multiple Profiles
and intensity based
Multiple Stacks
can either be saved as image stack
based data or as a topography based data.
If
the
Multiple Stack
data are saved in an intensity stack based format, correlation is performed
only in X- and Y- direction,
NOT
in Z-direction.
If the
Multiple Stack
data should be saved in the topography based format, the
Topography
checkbox
in the
Parameters
window has to be activated and an intensity threshold has to be chosen before the
experiment will be started.
Try to perform a single stack first to find the optimal acquisition settings and the appropriate
lower intensity threshold for topographic reconstruction.
In the topography based experiment the data are correlated in X-, Y-
AND
Z-direction.
•
The
Save
button in the
Profile & Stack Stitching
window saves topography based
Multiple
Stacks
experiments in two file formats.
(a)
XYZ-data file without correlation results (*.inf.dat)
The topography data file (.dat) contains the height data in 32-bit IEEE floating-point format. The file has
no additional header. All data of the first tile are stored in the file first then followed by the data of the
second tile and so on. The tile resolution and size information is stored in the .inf file.
The height values (32-bit IEEE floating-point format) are stored in the range 0…1 where the value 0
indicates that no height value has been determined for the pixel due to low intensity. All other values can
be multiplied with the
RangeZ
entry from the *.inf file to obtain the metric height value.
(b)
Information file with size of Multiple Stack Scan and automated correlation results (*.inf)
The information file (.inf) is formatted like a MS-Windows ini-file with sections and entries.
Section [Image information]:
Entries:
ImageSizeX
ImageSizeY
The horizontal and vertical number of pixels for the tiles.
TilesX
TilesY
The horizontal and vertical number of tiles that have been acquired
VoxelSizeX
VoxelSizeY
The horizontal and vertical pixel to pixel distance in meter.
RangeZ
The factor that has to be applied to the floating-point height data in the data
file to obtain metric height data.
Overlap
The relative fraction of the overlap region for adjacent tiles that has been used
to acquire the data in the range 0..1. The value 0.5 indicates that half of the
tiles overlap.
