摘要:

为了提高目标检测技术和开销目标检测研究的水平,我们引入了一种新的大规模数据集。该卫星图像数据集使与四个关键计算机视觉前沿有关的研究进展成为可能。我们利用一个新的过程,地理空间类别检测和限界框注释的三个阶段的质量控制。我们的数据是从WorldView-3卫星以0.3米的地面采样距离收集的,提供比大多数公共卫星图像数据集更高分辨率的图像。我们将xView与自然和头顶图像域中的其他目标检测数据集进行比较,然后使用Single Shot MultiBox Detector提供基线分析。xView是迄今为止最大、最多样化的公开对象检测数据集之一,在超过1,400平方公里的图像中拥有60个类别的100多万个对象。

英文摘要:

We introduce a new large-scale dataset for the advancement of object detection techniques and overhead object detection research. This satellite imagery dataset enables research progress pertaining to four key computer vision frontiers. We utilize a novel process for geospatial category detection and bounding box annotation with three stages of quality control. Our data is collected from WorldView-3 satellites at 0.3m ground sample distance, providing higher resolution imagery than most public satellite imagery datasets. We compare xView to other object detection datasets in both natural and overhead imagery domains and then provide a baseline analysis using the Single Shot MultiBox Detector. xView is one of the largest and most diverse publicly available object-detection datasets to date, with over 1 million objects across 60 classes in over 1,400 km^2 of imagery.
