Configuring Ranger E and D
Figure 5.1 – Hierarchy of parameters for the Ranger E. Ranger D has a similar hierarchy,
but has only one measurement component.
5.2 Setting Region-of-Interest
The Region-of-Interest (ROI) defines what part of the sensor to use for the measurements.
Using a smaller region on the sensor enables measurements at a higher rate.
The ROI is specified by two dimensions:
ROI-width Specifies which columns to use, and is set by specifying a start column
and the number of columns.
The ROI-width is set for the configuration, and is therefore common for all
components in that configuration.
ROI-height Specifies which rows to use, and is set by specifying a start row and the
number of rows.
The vertical location and height of the ROI is set for each component in a
configuration. This way, the sensor can be divided into separate regions,
where each region is used for a specific type of measurement.
Note that the HiRes Gray component (on Ranger E55 models) always
uses a specific sensor row for measurement – that is, the start row is al-
ways 512 and the number of row is always 1.
Figure 5.2 – ROI-width and ROI-height
If two components have overlapping ROIs, the Ranger issues a warning but continues to
measure. However, the measurement results will become corrupt.
