transform calculation.
The diagnostic screens show the black body pixels detected, and the apparent temperature
according to the Planckian locus law calculation.
Black Body Pixels
–
Relative colours result in pixels potentially on the Planckian Locus.
LogV Image
–
Log of the absolute value of the flame intensity. This indicates pixels sufficiently
bright to be considered for a match to the Planckian Locus test.
Temperature Image
–
Colour and intensity within the intensity error range, and then subject to
‘movement’ threshold, tests to determine if it fully meets the flame detection
requirements.
Thermopile Image
–
Displays the image as seen by the thermopile sensor.
Thermopile Overlay
–
Displays the thermopile sensor image superimposed upon the camera image.
This highlights the location of any hot sports or flame detections
Thermopile Web-page
This Web-page is only available on the FireVu Multi-Detector. It allows the area to be monitored
by the thermopile sensor to specified, as a rectangular region within the overall image, if required.
The region to be monitored is set by selecting the X and Y co-ordinates of the top left-hand corner
of the image, by pixel. The width and height of the rectangle can then be selected.
