Infrared sensor CEDIP Jade Infrared Uncooled
Camera

• The JADE UC is a low cost infrared camera which
  uses a highly sensitive
• microbolometer focal plane array of 320 x 240
  pixels.
• The JADE UC camera finds its application in
  process control, automation and local area
  surveillance. JADE UC can be remotely controlled
  by the CEDIP CIRRUS Win software or by the user
  software for integration into a more complex
  system. Outputs are analog video and digital 14
  bits video compatible with most third party frame
  grabber. JADE UC can be connected to the CEDIP
  ALTAIR software for live image acquisition and
  processing

Stereoscopic Acquisition (IRColour)

• Geometry IR/Colour calibration ?Estimation of
  an homographic matrix between the 2 images
  (sensors close and aligned)
• Synchronisation no electronic synchronisation
• Images are time stamped.
