摘要
古代墓葬作为反映早期各社会阶层及其生活状态的典型遗迹,是考古学的重要研究对象,目前有大量墓葬遗迹尚未发现。常规的考古调查手段工作效率不高,尤其在大范围、复杂环境区域难以实现全覆盖。基于深度学习的自动识别方法能够提高考古探测的效率,在遥感考古调查中发挥了重要作用。以新疆阿勒泰地区的古代圆形墓葬为研究对象,构建了首个古代圆形墓葬遥感数据集,选取Faster R-CNN、Cascade R-CNN、YOLOv5和YOLOv7四种典型的深度学习算法开展古代圆形墓葬检测的比较研究。结果表明,YOLOv5和YOLOv7的平均精度超过0.8,YOLOv7最高达到0.87,展现了出色的鲁棒性和广泛的适应性。基于WorldView2、WorldView3和国产GF2卫星数据的进一步测试结果显示,YOLOv7算法在识别具有斑点和环状特征的墓葬时具有明显优势。实验开展的比较研究为实现古代墓葬高精度的自动检测提供了有效方法,同时也为其他考古遗迹的自动检测提供了有价值的参考和借鉴。
Ancient tombs,as significant relics that mirror the early social class and its lifestyle,constitute crucial objects of archaeological research.However,numerous ancient tombs remain undiscovered.Traditional archaeological investigations of ancient tombs,especially those conducted in vast and complex environments,are often inefficient.The automatic identification method based on deep learning algorithms has the potential to enhance archaeological detection efficiency and thus plays an important role in remote sensing archaeological investigation.This paper focuses on ancient circular tombs in the Altai region of Xinjiang as the subject of research.We have built the first dataset of ancient circular tombs and conducted a comparative study utilizing four mainstream algorithms,Faster R-CNN,Cascade R-CNN,YOLOv5 and YOLOv7,to detect these tombs.The result reveals that the average precision of YOLOv5 and YOLOv7 exceeds 0.8,with YOLOv7 achieving a peak accuracy of 0.87,showcasing the robustness and adaptability of the YOLO algorithms.Additionally,we have tested the four deep learning algorithms on remote sensing data of varying resolutions,including WorldView2,WorldView3 and GF2 satellites.YOLOv7 emerges as the superior algorithm in terms of both efficiency and accuracy for identifying ancient tombs with blob and ring archaeological markers.This comparative study,not only offers an effective algorithm for the automatic detection of ancient tombs but also provides valuable insights for the automatic detection of other archaeological relics.
