Abstract

Assessing the grain yield of wheat remains a great challenge in field breeding trials.

Multispectral and RGB images acquired by UAVs offer a promising tool for in-season prediction yet with varying results during the growing season.

Therefore, enhancing prediction accuracy through optimizing multi-date models seems necessary but needs to be weighted with time and costs.

Multi-date models outperform single-date models, with repeated data collection during the grain-filling phase being most effective.

RGB indices can compete with multispectral indices.

基于多光谱和RGB图像的小麦籽粒产量田间表型数据融合提高模型性能

在田间育种试验中，小麦产量评估仍然是一个巨大的挑战。无人机获取的多光谱和RGB图像为季节性预测提供了一种很有前途的工具，但在生长季节会产生不同的结果。因此，通过优化多日期模型来提高预测精度似乎是必要的，但需要对时间和成本进行加权。多日期模型优于单日期模型，在灌浆阶段重复收集数据是最有效的。RGB指数可以与多光谱指数竞争。
