Remote-sensing indices and model outputs are proxies or estimates that require local validation.
Vineyard decisions depend on ripeness, water status, canopy variation, and disease pressure. Multispectral imagery can compute vegetation indices such as NDVI from red and near-infrared reflectance to estimate relative vine vigor; the index is a proxy, not a direct disease diagnosis. Computer vision can estimate grape-cluster counts for yield forecasts, with estimates calibrated against historical weights or field measurements. In one study, deep learning detected downy- and powdery-mildew symptoms in field images; performance depends on the dataset and testing conditions. A 2025 multispectral study estimated grape ripening and quality traits such as soluble solids, acidity, pH, and phenolic compounds, which may inform harvest timing but do not determine the optimum date by themselves. Weather and soil-moisture data can support variable-rate irrigation decisions by block, not identify an exact water requirement in every case. Fermentation sensors can track sugar, temperature, and pH for winemaker review.
Mapping relative vine vigor with multispectral reflectance across vineyard blocks.
Estimating yield from computer-vision cluster counts calibrated with historical weights.
Using weather and soil-moisture readings to inform block-level irrigation adjustments.
Monitoring sugar, temperature, and pH during fermentation to flag conditions for winemaker review.
Precision-viticulture systems can combine imagery, field sensors, and harvest samples to support site-specific monitoring. Models need validation across cultivars, seasons, canopy structures, and vineyard conditions. Growers and winemakers can use estimates as decision-support evidence while checking results against field observations and measured fruit or fermentation properties.

AI can help estimate canopy vigor, yield, disease symptoms, grape traits, and fermentation conditions in vineyards and wineries. Remote-sensing indices and model outputs are proxies or estimates that require local validation.
NDVI is calculated from red and near-infrared reflectance and can serve as a proxy for relative vine vigor; it is not a direct disease diagnosis or exact water measurement.
Les modèles de détection d'objets comptent les grappes et les baies à partir des images, puis mettent à l'échelle les comptes à l'aide des données de poids historiques pour estimer le rendement.
Multispectral cameras capture selected visible and non-visible bands, including near-infrared, which can be used to calculate vegetation indices such as NDVI.
Weather and soil-moisture models can inform block-level irrigation adjustments. They provide estimates, not a guarantee of the exact water requirement for every vine.
La surveillance du sucre, de la température et du pH permet aux vignerons de détecter rapidement les fermentations bloquées ou incontrôlées.
