wp1 colour imaging

Colour measurement

The CropReporter uses LED (light emitting diode) induced direct fluorescence imaging technology to image the plant health/stress status by calculation of Fv/Fm (variable fluorescence over saturation
level of fluorescence). Within a short time interval (≈800 ms) multiple images are captured.

wp2 efficiency photosynthesis

Efficiency photosynthesis

Plant parts contain chlorophyll and show fluorescence. Using a measuring protocol the minimal fluorescence, F0, and the maximum fluorescence, Fm, are captured by the camera. From these two images the maximum efficiency of photosynthesis of Photosystem II is calculated.

wp4 chlorophyll measurement

Chlorophyll measurement

Using the reflection image of the chlorophyll filter and a reference image in the NIR an image was calculated that is a measure for chlorophyll content.

Anthocyanin

Using the reflection image of the anthocyanin filter and a reference image in the NIR an image was calculated that is a measure for anthocyanin content

wp5 early detection of damage

Early detection of damage

Photosynthesis is a process that is response earlier to different stresses than the colour change of a plant does. Because of this effect you can see large differences with the PSII system and this is not visible yet by eye.

wp6 efficiency photosynthesis measured with mobile platform

Efficiency photosynthesis measured with mobile platform

By using a mobile platform to move the camera systems the camera’s can be used in any environment and location. Every camera system can be made mobile.

wp7 herbicide

Herbicide

To demonstrate the influence of two different types of herbicides, plants (whole plants) were sprayed with a formulation with the active ingredient bentazon. This is a herbicide that inhibits the photosynthesis on a whole plant level.
