Visualization Windows
The
visualization
window
is used for visualizing the result from the camera. Several visuali-
zation windows showing different results can be open at the same time. The visualization
windows are further described later on in this chapter.
The visualization windows can be opened from the menu bar
in
Ranger Studio main win-
dow (Choose

.
In Image mode, this Visualization window shows a grayscale 2D image. This is useful in
order to, for example, adjust the exposure time and to decide the region of interest.

In Measurement mode the View menu offers visualization windows for combined data, and
windows for range, intensity and scatter data as applicable. Scatter data is only be avail-
able in Rulers with the scatter option (S-version).
Figure 4.3 – Visualization windows with range, scatter and intensity images.
The visualization window always shows the measurement data as an 8-bit grayscale
image. This means that the original range measurement values are translated to 255
grayscale values, where 1 (black) corresponds to the bottom of the field-of-view (FOV) and
255 (white) corresponds to the top of the FOV. The value 0 means missing data.
In addition, the range profiles are re-sampled to get range values that are evenly distrib-
uted along the x-axis, to be able to display the measured objects with correct proportions.

the image displayed in the visualization window.
