针对水下作业的新型机器人视觉感知框架 Research Article

鲁岳1,陈星宇2,吴正兴1,喻俊志1,3,文力4

《信息与电子工程前沿（英文）》 2022年第23卷第11期页码 1602-1619 doi: 10.1631/FITEE.2100366

摘要：

水下机器人操作通常需要视觉感知（如目标检测和跟踪），但水下场景视觉质量较差，且代表一种特殊分布，会影响视觉感知的准确性。同时，检测的连续性和稳定性对机器人感知也很重要，但常用的基于静态精度的评估（即平均精度（average precision））不足以反映检测器的时序性能。针对这两个问题，本文提出一种新型机器人视觉感知框架。首先，研究不同质量的数据分布与视觉恢复在检测性能上的关系。结果表明虽然分布质量对分布内检测精度几乎没有影响，但是视觉恢复可以通过缓解分布漂移，从而有益于真实海洋场景的检测。此外，提出基于目标轨迹的检测连续性和稳定性的非参考评估方法，以及一种在线轨迹优化（online tracklet refinement，OTR）来提高检测器的时间性能。最后，结合视觉恢复，建立精确稳定的水下机器人视觉感知框架。为了将视频目标检测（video object detection，VID）方法扩展到单目标跟踪任务，提出小交并比抑制（small-overlap suppression，SOS）方法，实现目标检测和目标跟踪之间的灵活切换。基于ImageNet VID数据集和真实环境下的机器人任务进行了大量实验，实验结果验证了所作分析的正确性及所提方法的优越性。代码公开在https://github.com/yrqs/VisPerception。

A novel task-oriented framework for dual-arm robotic assembly task

《机械工程前沿（英文）》 2021年第16卷第3期页码 528-545 doi: 10.1007/s11465-021-0638-2

摘要： In industrial manufacturing, the deployment of dual-arm robots in assembly tasks has become a trend. However, making the dual-arm robots more intelligent in such applications is still an open, challenging issue. This paper proposes a novel framework that combines task-oriented motion planning with visual perception to facilitate robot deployment from perception to execution and finish assembly problems by using dual-arm robots. In this framework, visual perception is first employed to track the effects of the robot behaviors and observe states of the workpieces, where the performance of tasks can be abstracted as a high-level state for intelligent reasoning. The assembly task and manipulation sequences can be obtained by analyzing and reasoning the state transition trajectory of the environment as well as the workpieces. Next, the corresponding assembly manipulation can be generated and parameterized according to the differences between adjacent states by combining with the prebuilt knowledge of the scenarios. Experiments are set up with a dual-arm robotic system (ABB YuMi and an RGB-D camera) to validate the proposed framework. Experimental results demonstrate the effectiveness of the proposed framework and the promising value of its practical application.

摘要：人类驾驶与自主驾驶在对交通环境的理解方式上有着明显差别。首先，人主要通过视觉来理解交通场景，而机器感知需要融合多种异构的传感信息才能保证行车安全。其次，一个熟练的驾驶员可以轻松适应各种动态交通环境，但现有的机器感知系统却会经常输出有噪声的感知结果，而自主驾驶要求感知结果近乎100%准确。本文提出了一种用于无人车交通环境感知的视觉主导的多传感器融合计算框架，通过几何和语义约束融合来自相机、激光雷达（LIDAR）及地理信息系统（GIS）的信息，为无人车提供高精度的自主定位和准确鲁棒的障碍物感知，并进一步讨论了已成功集成到上述框架内的鲁棒的视觉算法，主要包括从训练数据收集、传感器数据处理、低级特征提取到障碍物识别和环境地图创建等多个层次的视觉算法。所提出的框架里已用于自主研发的无人车，并在各种真实城区环境中进行了长达八年的实地测试，实验结果验证了视觉主导的多传感融合感知框架的鲁棒性和高效性。

Public perception of environmental issues across socioeconomic characteristics: A survey study in Wujin

Jun BI, Yongliang ZHANG, Bing ZHANG,

《环境科学与工程前沿（英文）》 2010年第4卷第3期页码 361-372 doi: 10.1007/s11783-010-0017-4

摘要： In developing countries, there is controversy over the correct perception regarding environmental and developmental issues. Few studies have examined the perception of low-income nationals in regards to social and environmental issues. This paper looks at the relationship between socio-demographic factors and the groups’ perceived priority regarding environmental and social issues in Wujin County. The results indicated that most residents, specifically the young, government employed and the urban community consider environmental issues to be serious, especially in relation to air pollution and water pollution. Furthermore, many residents feel it is important to rank environmental problems that are related to other social and economic issues, and that environmental protection must be set as a priority in Wujin County. Compared to social issues, environmental concern was greater among the young, government employed, and the urban community, because of their higher education and affluence. In addition, 66.2% of residents consider environmental protection to be more important than economic development. Thus, environmental protection must be set as a high priority in Wujin County, in order to face the many social and environmental challenges inherent in development.

Luosi WEI, Zongxia JIAO

《机械工程前沿（英文）》 2009年第4卷第2期页码 184-191 doi: 10.1007/s11465-009-0034-9

摘要： A location system is very important for solder paste printing in the process of surface mount technology (SMT). Using machine vision technology to complete the location mission is new and very efficient. This paper presents an integrated visual location system for solder paste printing based on machine vision. The working principle of solder paste printing is introduced and then the design and implementation of the visual location system are described. In the system, two key techniques are completed by secondary development based on VisionPro. One is accurate image location solved by the pattern-based location algorithms of PatMax. The other one is camera calibration that is achieved by image warping technology through the checkerboard plate. Moreover, the system can provide good performances such as high image locating accuracy with 1/40 sub-pixels, high anti-jamming, and high-speed location of objects whose appearance is rotated, scaled, and/or stretched.

Perception of people for the risk of Tianwan nuclear power plant

《环境科学与工程前沿（英文）》 2010年第4卷第1期页码 73-81 doi: 10.1007/s11783-009-0151-z

摘要： A questionnaire survey of residents’ risk perceptions related to Taiwan nuclear power plant in China was carried out to explore the determining factors that affect individual risk perception. This study proposed to pursue a more comprehensive understanding of factors that affected individual risk perception to nuclear power plants. Covariance structure analysis was conducted using risk perceptions of nuclear power as dependent variable and including interest and knowledge levels of nuclear power, acceptability, benefit perception, trust in nuclear power operation, and trust in government as independent variables. The use of the hypothesis of Elaboration likelihood model (ELM) was also proposed. The results showed that persons with higher levels of interest and knowledge of nuclear power had their own perceptions of risk closely associated with acceptability and potential benefits of nuclear power. In contrast, persons with no interest in and knowledge of nuclear power would have risk perceptions related to their trust in nuclear operation and the government, which partially supported the ELM hypothesis. All these results indicated that the government in China plays an important role in rational risk perceptions, and well-designed communication of risks will help the public to be involved in risk management and improve people’s rational acceptance of risk.

基于定量属性的单目标视觉跟踪算法评价体系研究 Article

Wen-jing KANG, Chang LIU, Gong-liang LIU

《信息与电子工程前沿（英文）》 2020年第21卷第3期页码 405-421 doi: 10.1631/FITEE.1900245

摘要：视觉跟踪是计算机视觉领域热门研究课题之一。近年来，很多先进跟踪算法和性能评价基准相继发布，并取得巨大成功。现有评价体系大多定位于衡量整体性能，无法通过针对性的详细论证评估跟踪器的优势和缺点，且很多常用评测指标缺乏令人信服的含义解释。本文从测试数据、测试方法、测试指标3方面深入分析跟踪评价体系的细节。首先，归纳整理了12个反映图像序列不同特性的帧间视觉属性，并首次定量给出其归一化公式。基于这些属性定义，提出两种新的测试方法，即基于相关性的测试和基于权重的测试，使评价体系能更直观、更清晰地评定跟踪器各方面性能。然后，将所提测试方法应用于著名的跟踪挑战赛，即Video Object Tracking (VOT) Challenge 2017。测试结果表明，在目标尺寸快速或剧烈变化时，跟踪器大多表现不佳，即使基于深度学习的先进跟踪器也未能很好解决这一问题。此外发现，中心位置差错（center location error，CLE）性能指标虽未考虑到目标尺度，在实际测试中仍对目标尺寸变化很敏感。

摘要：监督式机器学习方法可自动分类新数据，且对数据分析非常有帮助。监督式机器学习的质量不仅依赖于使用的算法类型，也依赖于用于训练分类器的标注数据集的质量。训练数据集中的标注实例通常依赖于专业分析人员的手工选择与注释，且通常是一个单调与耗时的过程。标签可以在学习过程中为主动学习算法提供有用的输入，以自动确定数据实例的子集。交互式可视化标注技术是有前景的选择，它提供有效的视觉概览，分析人员可从中同时查看数据记录与选择项目标签。将分析人员置于循环中，生成的分类器可得到更高准确率。虽然交互式可视化标注技术的初步结果在某种意义上有前景的，考虑到用户标注可改善监督式学习，但是该技术的许多方面仍有待探索。本文使用mVis工具标注一个多元数据集以比较3种交互式可视化技术（相似图、散点矩阵与平行坐标图）以及主动学习。结果表明3种交互式可视化标注技术的分类准确率均高于主动学习算法，相对于散点矩阵与平行坐标图，用户主观上更偏爱使用相似图标注。用户也可以根据使用的可视化技术采用不同标注策略。

Design of an enhanced visual odometry by building and matching compressive panoramic landmarks online

Wei LU,Zhi-yu XIANG,Ji-lin LIU

《信息与电子工程前沿（英文）》 2015年第16卷第2期页码 152-165 doi: 10.1631/FITEE.1400139

摘要： Efficient and precise localization is a prerequisite for the intelligent navigation of mobile robots. Traditional visual localization systems, such as visual odometry (VO) and simultaneous localization and mapping (SLAM), suffer from two shortcomings: a drift problem caused by accumulated localization error, and erroneous motion estimation due to illumination variation and moving objects. In this paper, we propose an enhanced VO by introducing a panoramic camera into the traditional stereo-only VO system. Benefiting from the 360° field of view, the panoramic camera is responsible for three tasks: (1) detecting road junctions and building a landmark library online; (2) correcting the robot’s position when the landmarks are revisited with any orientation; (3) working as a panoramic compass when the stereo VO cannot provide reliable positioning results. To use the large-sized panoramic images efficiently, the concept of compressed sensing is introduced into the solution and an adaptive compressive feature is presented. Combined with our previous two-stage local binocular bundle adjustment (TLBBA) stereo VO, the new system can obtain reliable positioning results in quasi-real time. Experimental results of challenging long-range tests show that our enhanced VO is much more accurate and robust than the traditional VO, thanks to the compressive panoramic landmarks built online.
