Berry thinning in table grape production is a crucial operation that reduces the number of grapes before growth to promote berry enlargement and bunch shaping. However, the complex judgment criteria and need for quick decision-making make it extremely time-consuming for inexperienced workers to master this skill. To assist farmers in learning berry thinning expertise, this study proposes a system that performs 3D reconstruction of grape bunches and automatically identifies optimal berry selection for thinning. Conventional depth sensor-based and image-based 3D reconstruction methods have proven impractical in field environments due to lighting variations and the textureless surface characteristics of grape berries. Therefore, we propose a novel 3D reconstruction method for grape bunches combining 3D Gaussian Splatting with Random Sample Consensus (RANSAC)-based sphere detection. Furthermore, combinatorial optimization using genetic algorithms is applied to the estimated berry positions, automatically determining which berries to thin by maximizing inter-berry distances. |
