【摘要】 传统目标检测器通过水平边界框(Horizontal Bounding Box, HBB)定位目标，在检测方向角任意、分布密集、长宽比大、背景复杂的目标时，往往精度较低、泛化能力较差。在边界框中增加不同旋转角度的旋转目标框可有效解决上述问题，其被广泛应用在遥感图像、场景文本图像、货架商品图像等目标检测领域，具有重要研究价值。目前大多数工作旨在构建不同的旋转目标检测模型，对现有模型的归纳总结及深入分析的综述性工作较少。为此，对旋转目标检测现有研究成果进行了详细综述。首先根据当前流行的目标框表征方式，将目标框分为旋转矩形框(Oriented Bounding Box, OBB)、四边形边界框(Quadrilateral Bounding Box, QBB)和点集(Point set) 3种类型，并比较了不同旋转目标检测算法的优缺点、网络结构和性能；其次分析了目前常用的旋转目标检测数据集和性能评价指标；最后对目前研究中存在的问题进行简要总结和讨论，并对未来的发展趋势进行展望。更多还原

【Abstract】 Traditional object detector locates objects by horizontal bounding box(HBB),which often have low accuracy and poor generalization ability when detecting objects with arbitrary orientation angle, dense distribution, large aspect ratio and complex background.The above problems can be effectively solved by adding rotating target boxes with different rotation angles in the bounding boxes.This method is widely used in the fields of remote sensing images, scene text images, shelf goods images and other target detection, and has important research value.Most of the current works aim at constructing different models for rotating object detection, and there are fewer review works for summarizing and analyzing existing models in depth.Therefore, this paper provides a detailed review of existing research results on rotating object detection.Firstly, according to the current popular way of target box characterization, the target boxes are classified into three types of oriented bounding box(OBB),quadrilateral bounding boxes(QBB) and point set for generalized analysis, and simultaneously compare the advantages and disadvantages, network structures and performance of different rotating object detection algorithms.Secondly, the commonly used rotating object detection datasets and performance evaluation metrics are analyzed.Finally, the problems in the current study are briefly summarized and discussed, and the future development trend is prospected.更多还原
