Abstract
本发明提出一种面向多源高分遥感影像光伏板样本生成方法，属于遥感影像样本提取领域，本发明利用第三次国土变更调查数据中的光伏板数据来制作光伏板样本，可以大幅度的减少样本制作的时间。利用光伏板图斑的重心作为样本的几何中心点，根据图斑大小自动计算东南西北四个方向的扩充距离，不仅可以提高光伏板样本在水平翻转和垂直翻转后具备光伏板位置的多样性，还可以增加光伏板的上下文信息，进一步提高模型的泛化能力和边界精度。使用循环迭代的方式可以全自动化制作负样本，提高模型的正确率。整个流程仅需部分人工操作，基本实现了自动化样本制作，并且样本添加了位置、成像时间、空间分辨率、波段顺序等信息，便于入库与特异性模型训练。
