Challenge description

Description of the Challenge The challenge addresses new technologies to facilitate the operation of grape yield prediction in quantity and quality, with non-destructive system, potentially embedded on tractors. The aim is to provide a fast and reliable method enabling an early yield estimation to all the persons involved in the viticulture area.
Context

The vineyard production has always been stamped by its irregular yearly harvest quantity. The yield control is decisive for the harvest organisation and the wine quality.
Different methods try already to make a prediction of the yield by estimating the grape volume at harvest on geographical areas more or less widespread; or counting the inflorescences and the bunch-per-vine or the berry-per-bunch; or the weight of ripe berries or ripe bunches using berry growth parameters…
Control yield is actually done by operators at a different stages of the plant growth but it is very lengthy and boring. Furthermore, the estimation is based on the sampling method of berries in the parcel.

Fundamental requirements and constraints

Fundamental requirements and constraints From the existing methods, we notice that the major problems are :
1/ they need historic data acquisition on a long period of time, which is not always available,
2/ they need a too heavy implementation, manually counting grapes, bunches or berries,
3/ the quality of the results provided is limited and not really reliable: no more precise than 10%. This can be explained by the fact that the prediction is realised probably too early (July) because of the lack of human availability later
4/ the robustness of the sensors and equipment
5/ the price of the solutions
