Toward Estimating the Crop Coefficient of Vineyards Using a Smartphone Camera
Jonathan Jaramillo, Justine Vanden Heuvel, Kirstin Petersen
American Journal of Enology and Viticulture, 2025
We developed a smartphone camera and computer vision-based method to estimate vineyard crop coefficient by measuring shaded area, providing a low-cost, accessible alternative to Paso Panel measurements.
Inexpensive, Automated Pruning Weight Estimation in Vineyards
Jonathan Jaramillo, Aaron Wilhelm, Nils Napp, Justine Vanden Heuvel, Kirstin Petersen
2024 IEEE International Conference on Robotics and Automation (ICRA), 2024
We present a low-cost, computer vision-based approach using smartphones and structured light to estimate vineyard pruning weight, outperforming existing methods for VSP vines and extending to HC vines.
Mobile and Inflatable Interface for Human Robot Interaction
Jonathan Jaramillo, Andrew Lin, Emma Sung, Isabel Jane Hunt Richter, Kirstin Petersen
2021 18th International Conference on Ubiquitous Robots, 2024
We introduce a low-cost mobile robot platform with an inflatable human-scale interface, designed for safe and engaging human-robot interaction in crowded environments.
Low-Cost, Computer Vision-Based, Prebloom Cluster Count Prediction in Vineyards
Jonathan Jaramillo, Justine Vanden Heuvel, Kirstin Petersen
Frontiers in Agronomy, 2021
We developed a computer vision system that uses videos taken with a smartphone to estimate grape yield more accurately and efficiently than traditional manual counting methods.
