Action items

  •  Unknown User (joaoff) - will it be possible to record wind directions/intensity and sun intensity during testing?
  •  Can we measure waves?
  •  Unknown User (joaoff) and Jan Otto must make test objectives
  •  Unknown User (joaoff) must make "Minimum Viable Product" and "Maximum Viable Product" description
  •  Ask Lise/NEO about how they calibrate their cameras
  •  Determine the types of calibrations we need
  •  Harald and Unknown User (joaoff) will analyze the HICO data 
  •  Evelyn Honoré-Livermore will ask at IES and ISB to figure out if anyone knows deconvolution

 

Discussion

  • Can we see the complicated Mie scattering spectra from the HICO images?
  • If we can correct for it, can we get information on particle size distribution
  • What are the causes of photons?
  • On-board processing - flow suggestion from Unknown User (joaoff)
    • Set of models where HICO will be used as a proxy and then combined with results from drone test
    • Fast classification of the images
    • Score the images and make decision
    • Rest of the processing to be done on ground
  • Can we see/detect the difference between water and water vapor?
  • Can we get good information even without high SNR? Are the signatures different enough?

 

Roadmap

Ultimate goal is to reach TRL9: Quantitative measurement og algae turbidity (copepods, temperature, salinity, waves, clouds, aerosols, atmosphere, sensor status)

Overview of HSI camera

Testing and verification

  • Test 1: Hopavågen tidal basin X 2
    • In-situ imaging
    • In-site measurmenet
    • Estimate the size of the pixels
    • The drone will be flying at 10-15 meters height
    • If there are ripples in the water, fly really close to them so that neighboring pixels have the same ripple

  • Test 2: Bridge test 
    • Have a camera mounted over time at a bridge
    • Have planks at different depths with RGB
    • Look at what we see
    • Can we measure the same things in different conditions?

  • Test 3: Ladder test
    • Use different shades of grey to make reference
    • Prepare test by doing ground truth (without water)
    • And then put them in water
  • Test 4: Across the fjord
    • Image across fjord
    • Preferable over time
