摘要
精准地检测建筑物目标对于城市规划、智慧城市建设和军事民事活动中均有重要意义。针对高分辨率遥感影像中密集型建筑物检测框重叠比高的问题,本文提出了一种Correg-YOLOv3(corner regression-based YOLOv3)检测方法,该方法以YOLOv3网络架构为基础,通过嵌入角点回归机制,增设一个关于顶点相对于边界框中心点的偏移量的额外损失项,扩展其输出维度,使其可同时输出矩形检测框及建筑物角点,实现密集分布的建筑物精准定位。最后,通过试验对本文方法进行定性和定量的评估。试验研究结果表明:本文方法检测精度、召回率、F1和平均精度分别达到了96.45%、95.75%、96.10%和98.05%,较原算法YOLOv3分别提高了2.73%、5.4%、4.1%和4.73%。因此,本文方法有效解决了高分影像中密集型建筑物的检测问题。
The exploration of building detection plays an important role in urban planning, smart city and military. Aiming at the problem of high overlapping ratio of detection frames for dense building detection in high-resolution remote sensing images, we present an effective YOLOv3 framework, corner regression-based YOLOv3(Correg-YOLOv3), to localize dense building accurately. This improved YOLOv3 algorithm establishes a vertex regression mechanism and an additional loss item about building vertex offsets relative to the center point of bounding box. By extending output dimensions, the trained model is able to output the rectangular bounding boxes and the building vertices meanwhile. Finally, we evaluate the performance of the Correg-YOLOv3 on our self-produced data set and provide a comparative analysis qualitatively and quantitatively. The experimental results achieve high performance in precision(96.45%), recall rate(95.75%), F1score(96.10%) and average precision(98.05%), which were 2.73%, 5.4%, 4.1% and 4.73% higher than that of YOLOv3. Therefore, the proposed algorithm effectively tackles the problem of dense building detection in high-resolution images.
