摘要：近年来连接建筑之间的廊桥结构逐渐发展为一种新型结构,由于很多连廊结构体量较大,施工高度较高,在吊装施工和拆卸支撑过程中的结构应力、位移等变化规律较难通过施工理论计算来精确模拟,因此通过结构监测来实时追踪结构关键部位的应力、位移参数的变化情况是一种有效确保结构安全的方法.本文介绍了针对宁波某酒店项目开发的定制结构监测系统在该项目钢结构连廊吊装施工过程中的应用,通过对整个吊装与卸载施工阶段的结构主桁架关键部位的应力、温度变化进行实时监测,并对获得的监测数据进行分析,总结关键施工阶段结构应力变化的相关规律,为同类工程的施工安全保障提供参考.

摘要：在城市园林建设中,对花卉色彩图像进行有效匹配,可以更好的提升城市园林建设水平。对花卉图像的匹配,需要利用未标定的透视图像,从而恢复参数以及标记点的三维空间坐标,完成对花卉色彩图像的匹配。传统方法剔除部分深度误差较大的花卉三维点,计算出整体花卉场景的三维点云,但忽略了恢复相应参数,导致匹配精度偏低。提出基于分水岭的城市园林建设中花卉色彩图像匹配方法。融合于分水岭方法进行花卉场景图像的分割,利用模糊均值方法将相似度较高的花卉形态区域进行合并,得到花卉边缘点匹配约束条件,将花卉轮廓上已匹配的特征角点定义为基准点,并利用未标定的透视图像恢复相机的参数以及标记点的三维空间坐标,以此为依据完成对城市园林建设中花卉场景图像匹配。仿真证明,所提方法花卉色彩图像匹配效果好,为提升城市园林建设水平奠定了结实的基础。

摘要：The sensing capabilities of a soft arm are ofparamount importance to its overall performance as they allow precise control of the soft arm and enhance its interactionwith the surrounding environment. However, the actuationand sensing of a soft arm are not typically integrated into amonolithic structure, which would impede the arm’s movement and restrict its performance and application scope. Toaddress this limitation, this study proposes an innovativemethod for the integrated design of actuator structures andsensing. The proposed method combines the art of kirigamiwith soft robotics technology. In the proposed method, sensorsare embedded in the form of kirigami structures into actuatorsusing laser cutting technology, achieving seamless integrationwith a soft arm. Compared to the traditional amanogawakirigami and fractal-cut kirigami structures, the proposedmiddle-cut kirigami (MCK) structure does not buckle duringstretching and exhibits superior tensile performance. Based onthe MCK structure, an advanced interdigitated capacitivesensor with a high degree of linearity, which can significantlyoutperform traditional kirigami sensors, is developed. Theexperimental results validate the effectiveness of the proposedsoft arm design in actual logistics sorting tasks, demonstratingthat it is capable of accurately sorting objects based on sensorsignals. In addition, the results indicate that the developedcontinuum soft arm and its embedded kirigami sensors havegreat potential in the field of logistics automation *** work provides a promising solution for high-precisionclosed-loop feedback control and environmental interaction ofsoft arms.
