从广域巡天数据中检测太阳系内移动物体的最大挑战之一是区分真实天体信号与噪声等干扰源。传统方法依赖人工目视验证,导致人力成本高昂。为降低对人工干预的依赖,本文提出一种融合卷积块注意力模块的多输入卷积神经网络,专门优化此前开发的移动物体检测系统。该方法包含两项创新:一是多输入架构,可同步处理多张堆叠图像;二是引入卷积块注意力模块,使模型在空间和通道维度上聚焦关键特征。这些改进促进了多输入信息的高效学习,显著提升了移动物体检测的鲁棒性。模型在约2000张观测图像的数据集上评估,准确率达近99%,AUC > 0.99,表明分类性能优异。通过调整检测阈值,新模型相比人工验证可减少超过99%的人工工作量。
原文摘要 · Abstract (English)
One of the greatest challenges for detecting moving objects in the solar system from wide-field survey data is determining whether a signal indicates a true object or is due to some other source, like noise. Object verification has relied heavily on human eyes, which usually results in significant labor costs. In order to address this limitation and reduce the reliance on manual intervention, we propose a multi-input convolutional neural network integrated with a convolutional block attention module. This method is specifically tailored to enhance the moving object detection system that we have developed and used previously. The current method introduces two innovations. This first one is a multi-input architecture that processes multiple stacked images simultaneously. The second is the incorporation of the convolutional block attention module which enables the model to focus on essential features in both spatial and channel dimensions. These advancements facilitate efficient learning from multiple inputs, leading to more robust detection of moving objects. The performance of the model is evaluated on a dataset consisting of approximately 2,000 observational images. We achieved an accuracy of nearly 99% with AUC (an Area Under the Curve) of >0.99. These metrics indicate that the proposed model achieves excellent classification performance. By adjusting the threshold for object detection, the new model reduces the human workload by more than 99% compared to manual verification.
