TRANSCRIPT

Miniature multifunctional hyperspectral camera based on

novel IMEC HSI technology

Farmers will need to produce more food in the next 50 years than in the last 10,000 years combined (Mission Critical, May 2014)

Population growth and deficiency of land determine the high demand for resource-saving technologies

Precision Farming● Sensing● Automation

Airborne hyperspectral diagnostics of vegetation

Electromagnetic spectrum

Interaction of light with matter

Colour vision

Hyperspectral imaging

Novel hyperspectral imaging sensor

FlexibilityWorld's smallest and lightest HSI sensor ● 6 x 4 x 4cm● 150g

Accuracy & PrecisionNo trade-off between spatial and spectral resolution

Plug & Play● Integrated battery● Integrated storage● Out-of-the-box field

ready

Compatibility● Automatic/external

triggering● Trigger in, Event out● Auxiliary GNSS/INS

input● Reference integration

on senseFly eBee● HSI data supported by

major decision support system providers including Pix4D and AgriCircle

Conversion of raw data into full-resolution HSI data cubes

Radiometric and atmospheric correction

Geometric correction, registration and orthorectification

Georeferencing and generation of hyperspectral orthophoto

HSI data acquisition and processing methodology

Seeding Crop establishment

Yield protection Yield delivery

3D aerial imagery and mappingEvaluation of soil quality and fertility

Early identification of crop diseasesIdentification of environmental stressesMonitoring of crop development and growth

Detection and control of weeds and invasive species Optimizing use and distribution of chemicalsWater and nutrient use efficiency

Yield forecasting

Timely control of crop diseases

DECISION SUPPORT INFORMATION: our hyperspectral imaging technology helps farmers to maximize productivity and take management decisions throughout the life cycle of crops

DECISION SUPPORT INFORMATION: our hyperspectral sensor also provide unique information in the field of forestry and therefore help foresters with the management of forests stands

● Spatial distribution and inventory of species● Diseases and water stress● Timber volume● Clear-cut and burned areas

M. A. Wulder 2014

Basic vegetation indices● Green biomass

○ NDVI = (NIR-Red)/(NIR+Red)○ GNDVI = (780-550)/(780+550)○ SAVI = 1.5 (800-670)/(800+670+0.5)

● Water status○ WI = 900/970

● Chlorophyll content○ Chl I = 740/720○ NDI 1 = (750-705)/(750+705)○ NDI 2 = (780-710)/(780-680)○ NDI 3 = (850-710)/(850-680)○ mND = (750-705)/(750+705-2x445)○ mSR = (750-445)/(705-445)

● Nitrogen status: ○ NDRE = (790-720)/(790+720)
