Overview of the MARVIN project

Project focus – automated tomato seedling inspection (2008-2012).

Project based on the PhD project (2008) by my colleague Nicole

Koenderink*

Financed by a consortium of breeders/ plant growers; RijkZwaan,

Monsanto, Syngenta, Enza, Incotec, Bejo, Nunhems and others

High accuracy plus high throughput, tough specs;

● 18.000 seedlings per hour

● Accurate quality grading similar to a human expert.

Future work

Within EPPN – WP3 Novel Sensors:

Using 3D to measure subtle colour differences on irregular surfaces

(leaves)

Plant architecture of larger plants (height of max. 70 cm)

We are interested in setting up a research collaboration
