  • Imaging

2 imaging booths compatible with 160 cm high and 100 cm wide plants :
- 1 3D visible imaging booth with top and side views (Sony DFW-SX900, Sony Corp., Tokyo, Japan) compatible with 200 cm high and 200 cm wide plants.
- 1 2D near infrared imaging booth.
One imaging cycle lasts between 30 and 40 seconds.

  • Software

- The movement of the plants on the conveyor, the image acquisition and the irrigation system is controlled by a control PC and the LemnaLauncher software (LemnaTec, GmbH, Wüerselen, Germany).
- Environmental data acquisition is carried out using National Instrument programs.
- A PhenoArch database is under development to manage these environmental data, lemnatec image analysis or ad-hoc developed.

  • Computing Server

A computing server automatically performs the image analysis (DELL Power Edge M610). The data is hosted on a database server (DELL Power Edge R410, DELL MD1200) with a capacity of 13 TB.
