中文摘要：为提高大型生活垃圾卫生填埋场的堆体覆膜穿刺、撕裂等常见病害的巡检效率，以广州市兴丰生活垃圾卫生填埋场为研究对象，基于无人机航拍和深度学习模型，考察了无人机的选型和巡航参数，使用无人机采集病害样本并在病害图像识别模型中采用过采样的训练策略。并在YOLOv5 模型上增加细微目标识别层，可实现较高的识别准确率与召回率。研究结果表明:在病害图库样本数量相对有限的前提下利用过采样的策略提升了样本的代表性与均衡性，显著提高了模型病害识别的准确率。无人机结合高精度RTK定位技术能准确定位航拍照片坐标，解决了无明显参照物下覆膜病害定位困难的问题。通过查询病害缺陷照片的地理信息，可以快速找到病害位置，有助于及时开展修复作业。

外文标题：Research on Intelligent Identification of Film Covering Diseases in Large Landfill Based on UAV and Deep Learning

外文摘要：In order to improve the inspection efficiency of large domestic waste sanitary landfill for diseases such as puncturing and tearing of the covering film,the Xingfeng landfill in Guangzhou was taken as an example.The selection and cruise parameters of unmanned aerial vehicles(UAV)were investigated based on UAV aerial photography and depth learning model,the disease samples collected by UAV were trained by oversampling strategy in the disease image recognition model.A subtle target recognition layer was added to the YOLOv5 model,which achieved high recognition accuracy and recall rate.The test results showed that the oversampling strategy improved the representativeness and balance of the samples and significantly improved the accuracy of disease identification of the model under the condition that the number of samples in the disease map database was relatively limited.UAV combined with high-precision RTK positioning technology could accurately locate the coordinates of aerial photos,solved the problem of difficult positioning of film coating diseases without obvious reference objects.By querying the geographic information of disease defect photos,the location of the disease could be quickly found and repair operations could be carried out in a timely manner.
