Every operation of the machine is a cycle<\/strong>. Cycles are run one-off or scheduled as jobs, and every measurement is recorded and linked to the plant and the time of measurement.<\/p>\n\n\n\n

\"Instruments
The instrument head of the upper gantry: cameras, halogen lighting, laser profilometer, Walz fluorometer.<\/figcaption><\/figure>\n\n\n\n

Weighing and watering<\/h2>\n\n\n\n

The lower gantry lifts the pot and places it on a balance. From one day to the next, the difference in mass gives the water consumed by the plant.<\/p>\n\n\n\n

Watering delivers a precise volume, or whatever is needed to bring the pot back to a target mass<\/strong> \u2014 the basis of controlled water-stress studies. Two means: a peristaltic pump with flow control for fine dosing, and solenoid valves for large volumes.<\/p>\n\n\n\n

Identification<\/h2>\n\n\n\n

A Keyence SR-1000 reader reads the Data Matrix code stuck under each pot and on each tray. The machine knows which plant occupies which position and reports moved or missing pots.<\/p>\n\n\n\n

Colour and thermal imaging<\/h2>\n\n\n\n
\n
\n

A JAI colour camera and a FLIR A700 thermal camera photograph each plant under halogen lighting. Leaf area and colour indices are calculated automatically; the thermal image shows the plant\u2019s water status.<\/p>\n\n\n\n

3D shape and height<\/h2>\n\n\n\n

A Wenglor weCat3D laser profilometer scans the trays and reconstructs the 3D shape of the plants. This yields a point cloud and the height of each plant, measured every day.<\/p>\n\n\n<\/div>\n\n\n\n

Hyperspectral imaging<\/h2>\n\n\n\n

Two Specim cameras, FX10 for visible and near infrared (VNIR) and FX17 for short-wave infrared (SWIR), acquire the spectral signature of each plant for detailed physiological analyses.<\/p>\n\n\n\n

Chlorophyll fluorescence<\/h2>\n\n\n\n

The MAXI head of a Walz IMAGING-PAM moves above each plant and runs the protocol chosen in the job (Fv\/Fm\u2026). It is a direct indicator of photosynthetic performance.<\/p>\n\n\n\n

Photogrammetry<\/h2>\n\n\n\n

A grid of photos taken above a tray allows a detailed 3D reconstruction of the plants.<\/p>\n\n\n\n

\"Reconstruction

Calibrations<\/h2>\n\n\n\n

Watering, profilometer, cameras, lighting and the hyperspectral white reference are calibrated from the supervision interface, to keep measurements accurate over time.<\/p>\n\n\n\n
