Field Scanalyzer


The FIELD SCANALYZER is a fully automated system designed to capture deep phenotyping data from crops and other plants growing in field environments. A rigid motorised gantry supports a weatherproof measuring platform that incorporates a wide range of cameras, sensors and illumination systems. The FIELD SCANALYZER delivers highly detailed information to monitor growth and physiology continuously, throughout the lifetime of plants.

Sensor Bay

All sensors are mounted in a separate weather-proof cabinet which is moved over the field by the supporting gantry. The maximum total payload of the sensor bay is 500 kg which allows for additional sensors if required.

RGB is the most widely used camera type in plant phenotyping. Visible imaging in plant phenotyping is the simplest method to capture plant physiological information. Applications range from the construction of growth profiles of the shoot from time series data, to the quantification of pathogen resistance from high-throughput compound screens.

Infra-Red (IR) cameras capture thermal radiation and IR imaging can be used to monitor the transpiration efficiency of leaves and to monitor water stress.

Hyperspectral imaging, also known as imaging spectrometry, is widely used in the field but usually remotely. The FIELD SCANALYZER is able to image at close range (2.2m above the canopy) and with high repeatability. Hyperspectral cameras produce a stack of images (hyperspectral data cube), where each image represents a narrow wavelength range of the electromagnetic spectrum.

PS2 Fluorescence analysis addresses status and functions of the chlorophylls that are main components of the light harvesting complexes. The system emits an intense LED flash for 1 second during which 25 images are recorded. From these images variable fluorescence (Fv) can be compared to the saturation level of fluorescence (Fm) and used to assess quantum yield of the PS2 photochemistry.

Laser Scanners are able to scan the plant canopy with very high cubicle resolution using an NIR Laser (840 nm) to ensure high reflectance by plant tissue and minimal physiologic interaction (eg chlorophyll excitation). Below is an example of coarse synthetic point cloud for field data, visualized with white points using shading for a better characterization. A height map can be extracted by encoding the height with colour.

Wheat Ears Segmentation

This process may be used to propose the development stage of the wheat by analysing the size of the ears.
