Ground-Based Thermal Imaging for Assessing Crop Water Status in Grapevines over a Growing Season
Zheng Zhou,Geraldine Diverres,Chenchen Kang,Sushma Thapa,Manoj Karkee,Qin Zhang,Markus Keller +6 more
TL;DR: In this paper , a robust strategy to assess crop water status in grapevines is proposed, where a custom-developed algorithm was created to automatically derive canopy temperature (Tc) and calculate crop water stress index (CWSI) from the acquired thermal-RGB images.
Decision-support system for precision regulated deficit irrigation management for wine grapes
TL;DR: In this article , a decision support system for managing precision RDI in vineyards is presented, consisting of a soil moisture prediction model and an RDI scheduling model developed based on artificial neural networks (ANN).

Assessment of Water Stress in Vineyards Using On-The-Go Hyperspectral Imaging and Machine Learning Algorithms
TL;DR: In this article , the applicability of hyperspectral images acquired from a ground-based utility vehicle was analyzed to classify plant water stress into three categories: no to mild water stress, moderate water stress and severe water stress.
