针对跨场景情况下图像亮度不一致导致的深度缺陷检测模型泛化性能差的问题,提出基于特征过滤与特征解耦的域泛化(FF-FDDG)模型.模型包含设计的亮度过滤-残差模块(LFR),该模块通过实例归一化过滤亮度变化特征,并从被过滤的特征中提取缺陷高相关性且亮度低关联性的特征,并将这些特征与实例级归一化后的特征进行融合,以增强模型在跨场景图像亮度变换情况下的泛化能力.提出对比白化损失(CWL)函数,该函数通过解耦特征中亮度变换特征和缺陷纹理特征,引导模型学习缺陷纹理特征,以提升模型泛化能力.在从光伏电池制造环境中收集的跨场景光伏电池表面缺陷数据上进行实验,结果表明,相较于现阶段最先进的域泛化模型,所提出的FF-FDDG在跨场景情况下的平均检测精度(mAP)均值提升5.01%.

针对圆筒型FPSO总体结构强度准静态设计方法依赖工程师经验的局限性,将设计波法引入圆筒型FPSO总体结构强度校核,提出了针对特征荷载选择的优化算法。该方法通过分析圆筒型FPSO总体结构承载特点和失效模式,结合常用特征载荷中有相同设计波的特征荷载,选择了舷侧外板波浪压力、上部模块重心处的水平和垂向加速度,作为设计波筛选的特征载荷;并根据圆筒型FPSO结构对称性,减少加载浪向,优化设计波搜索相位;基于本文方法的校核工况减少了60%,有效提升了校核效率。该方法已被应用于中国首条完全自主设计的圆筒型FPSO“海洋石油122”平台的强度校核中,校核结果通过了挪威船级社认证,该平台目前已完成设计,进入建造阶段,这也说明了本方法的可行性以及对后续同类FPSO设计的借鉴意义。

Real-time object tracking via least squares transformation in spatial and Fourier domains for unmanned aerial vehicles

引用

Chinese Journal of Aeronautics 2019年第7期32卷 1716-1726页

作者： Xiaoyuan YANG Ridong ZHU jingkai wang Zhengze LI School of Mathematics and Systems Science Beihang University

This paper addresses the problem of real-time object tracking for unmanned aerial vehicles. We consider the task of object tracking as a classification problem. Training a good classifier always needs a huge number of samples, which is always time-consuming and not suitable for realtime applications. In this paper, we transform the large-scale least-squares problem in the spatial domain to a series of small-scale least-squares problems with constraints in the Fourier domain using the correlation filter technique. Then, this problem is efficiently solved by two stages. In the first stage, a fast method based on recursive least squares is used to solve the correlation filter problem without constraints in the Fourier domain. In the second stage, a weight matrix is constructed to prune the solution attained in the first stage to approach the constraints in the spatial domain. Then, the pruned classifier is used for tracking. To evaluate proposed tracker’s performance, comprehensive experiments are conducted on challenging aerial sequences in the UAV123 dataset. Experimental results demonstrate that proposed approach achieves a state-ofthe-art tracking performance in aerial sequences and operates at a mean speed of beyond 40 frames/s. For further analysis of proposed tracker’s robustness, extensive experiments are also performed on recent benchmarks OTB50, OTB100, and VOT2016.

新冠疫情重构了个体交往方式,促进了交往空间的数字化与社会的媒介化。东京奥运会在延期一年后以无观众的形式举行,成为奥运史上一场独特的体育盛会。奥运会开幕式作为典型的全球性媒介仪式,呈现出高度媒介化、符号化、全球化的特征。东京奥运会开幕式通过对本土与全球文化符号的组合编码,呈现了全球性叙事、本土性叙事、连接性叙事、传承性叙事四种方式,加深了受众对于东京作为两次奥运会主办城市的印象,展现出日本作为文化大国的自信心理与另类的文化风格,实现了“以人为本,平等多元”的奥运精神叙事,并在仪式中通过感伤与共情唤起后疫情时代下人们对生命意义的思考。由此得出跨文化传播的三点启示:重视自我文化认知,精确锚定共同解释项;强化国家责任修辞,用本土语言讲全球故事;巧用非语言符号叙事,消减文化折扣。
