Abstract
• The study presents a precision, training-free crop segmentation algorithm that extracts important phenotypic traits from 3D point cloud data. • We validated the algorithm effectively utilizes advanced clustering techniques, demonstrating strong performance even in densely planted environments. • A user-friendly GUI allows farmers to easily access data, facilitating improved crop monitoring and management for precision agriculture technology. This study presents a novel AI-driven solution designed to enhance sustainable resource management and increase accessibility for farmers through visualized and digitalized tree information. The proposed methodology includes optimizing drone mapping for effective data coverage, capturing high-resolution imagery, and generating a 3D Point Cloud, with a particular emphasis on the integration of Weighted K-means, Density-based spatial clustering of applications with noise (DBSCAN), and cluster separation algorithms to develop a high-precision, training-free stepwise crop segmentation algorithm for extracting essential phenotypic traits such as crop height and canopy volume. The algorithm was validated using avocado trees in Tanzania and hazelnut trees in Canada, demonstrating its robustness across different tree types and planting conditions. Notably, this study highlights the feasibility of extracting crop height without constructing a Digital Terrain Model (DTM), thereby mitigating errors associated with DTM inaccuracies. The proposed stepwise segmentation algorithm achieved a height estimation R 2 of 0.967 and volume estimation R 2 of 0.91 for avocado trees, demonstrating high accuracy without the need for DTM or training data. The developed algorithm, coupled with a user-friendly graphical user interface (GUI), provides farmers with a reliable tool for monitoring crop health and optimizing field management, representing a significant advancement in precision agriculture technology with wide-ranging applicability.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
