Figure 5.12: ROI definition in 3D modes
The 2D lines must not be placed inside a laser peak scan area, otherwise the peak
detection will be seriously affected.
5.2.9 3D data format
Cameras with version 2.1 and later have an additional property DataFormat3D
which has an effect on the organisation of the 3D data. Camera prior to this
version have always
DataFormat3D
=0, although this property is not available.
For every peak there are 4 lines that contain the 3D data. Every pixel contains 8 bits of 3D data
which are always placed in the 8 LSB. A table with the bit assignment of the 3D data for
DataFormat3D
=0 is shown in Fig. 5.13 and with
DataFormat3D
=1 in Fig. 5.14. Note that every value
described in this table (with exception of STAT data) is the value for the corresponding image
column. The peak position coordinate (PEAK) is relative to the scan area of the peak. To get
the absolute position on the image sensor, the value Peak0_3DY must be added for peak 0
(Peak1_3DY must be added for peak 1).
LL_HEIGHT and LL_WIDTH values are explained in Fig. 5.13 and in Fig. 5.14.
STAT value: the status (value) of some parameters and internal registers are placed here. The
status information is described in Section 5.10.2. In every pixel (column) 4 bits of this status
information send, starting with the LSB in the first column.
