摘要:

快速筛选黄化植株,有利于果园问题植株的精准定位与防控管理。基于无人机RGB图像的深度学习已被广泛应用于农业领域的快速检测,但基于YOLOv8网络架构的无人机多光谱图像识别报道较少。本研究建立了一种基于YOLOv8网络架构和无人机多光谱影像的柑橘植株识别分析方法,并通过特征波段筛选来进行方法优化和比较。结果表明:植株样本与背景的光谱特征有很大差异,而黄化植株与健康植株较难区分。基于无人机RGB影像建立的模型,对柑橘健康植株的识别效果较佳,但对柑橘黄化植株的识别效果较差。增加训练图片的光谱影像通道数量后, 模型对黄化植株的识别精度呈上升趋势。特征波段筛选对模型识别精度存在影响,当特征比重之和大于90%时,模型预测效果良好。本研究为进一步开发更稳定、高效,可大范围应用的柑橘黄化植株快速监测方法,和探索多光谱影像与深度学习结合的方法在农业领域的应用奠定了基础。

Abstract:

Rapid screening of yellowed plants is beneficial for the precise positioning and control of unhealthy plants in orchards. Deep learning based on RGB images of unmanned aerial vehicle (UAV) has been widely applied for rapid detection in agriculture, but there are few reports about the deep learning based on multispectral images of UAV. This study proposed a detection and analytical framework for citrus trees based on YOLOv8 network architecturfe and UAV multispectral data, and further optimized and compared the model’s performance via characteristic band screening. The results showed that the features differed between citrus plants and background, but could not differ between healthy plants and chlorotic plants. Detection model of based on RGB images of UAV performed well on healthy citrus plants, but not well on chlorotic citrus plants. By increasing spectral images channels of training images, the recognition accuracy of chlorotic plants was improved. Bands selection had impact on the accuracy. When the cumulative proportion of feature was greater than 90%, the model performed well in prediction. This study provided a basis for developing a widely used, stable and efficient rapid monitoring method for citrus chlorotic plants, as well as advancing the integrated application of multispectral remote sensing and deep learning in precision agriculture.
