Smartphone Leaf Imaging

Standard RGB colour images of leaves are used as a record of crop health. Rather than take many images, representative leaves from each variety can be imaged using a smartphone.  Computer vision algorithms are used to produce quantitative indices of greenness, redness and blueness. These are related to chlorophyll, anthocyanine and carotenoid plant pigment concentrations.

Leaf pigment report

Leaf images are taken using a Leafbox, which allows the calculation of chlorophyll and carotenoid values. These index values can be thought of as similar to micro-molar (μM) concentrations of pigments in solution.

Changes in chlorophyll and carotenoid levels can be used to monitor responses to nutritional interventions and alert to progressive changes in plant health. Following extensive growth and fruit bearing, leaf pigment concentrations dropped. To restore the energy efficiency of the Centenary leaves, a liquid feed (N:P:K 8:34:32) was applied in weeks 22, 23 and 24. The figure above shows a marked increase in chlorophyll concentration by week 25. A similar response is seen in week 30 following further nutrient application in week 29.
