Overlays

The FLIR A68/A38 series camera can enable graphic overlays in the output image.
Available overlays include: a reticle, colormap legend, frame counter, metadata, zone
corners and alarm status. Each overlay can be individually enabled/disabled. Their
positions are configurable. A global overlay mode parameter allows turning on or off all
enabled overlays.
Metadata
Frame
Counter
• The reticle can be used to highlight specific regions.
• The colormap legend indicates the relative intensity of the different colors or
greyscale values.
o Starting with firmware 2.50, the colormap for the FLIR A68/A38 series
also prints the minimum, middle and maximum temperature values
associated to each pixel intensity or color.
• The frame counter increments with each frame acquired and is reset when the
acquisition is stopped (therefore when snapping single frames the counter
always reads 0).
• Frame metadata is normally transferred separately from the pixels but it can be
overlaid in the image itself for validation by tools that do not support GigE
Vision's Extended Chunk Data payload. For more information refer to the
Metadata section.
• The Zone overlays highlight the corners of the Zones where the camera
computes statistics; see features zoneSelector, zoneX1, zoneX2,
zoneY2 in the
