为研究反向累加生成序列绝对灰度的变化规律,基于原始序列与其一次反向累加生成序列的级比关系,推导了整数阶反向累加生成序列绝对灰度的一般表达式及其相关性质。结合实际问题背景,讨论了融合绝对灰度的反向累加灰色模型在突发灾害事件预测中的应用效果。研究结果表明:当原始序列的绝对灰度大于0.6时,进行反向累加生成变换能够有效降低序列的绝对灰度,当原始序列的绝对灰度小于0.25时,对序列进行反向累加生成变换会增大序列的绝对灰度。研究结论为灰建模的模型选择及序列预处理方式的选择提供参考。

针对机器视觉定位引导系统中外界因素导致eye-in-hand方案的相机细微偏移的问题,提出一种相机偏移像素坐标矫正方法。为消除相机偏移对初始标定参数的影响,基于针孔相机投影模型,建立相机偏移像素坐标估计模型;通过设计相机确认位划分图像区域,解析每个子区域中描述相机偏移模型的参数;以物体特征点偏移后像素坐标为已知条件,求解其偏移前像素坐标,以保证初始标定参数的有效性。实验结果表明,相机偏移像素坐标矫正方法能够有效修正螺栓通孔固定的相机偏移引起的像素坐标误差,修正误差在1 pixel以内。

his paper adopts the 3-3-2 information processing method for the capture of moving objects as its premise, and proposes a basic principle of three-dimensional (3D) imaging using biological compound eye. Traditional bionic vision is limited by the available hardware. Therefore, in this paper, the new-generation technology of microlens-array light-field camera is proposed as a potential method for the extraction of depth information from a single image. A significant characteristic of light-field imaging is that it records intensity and directional information from the lights entering the camera. Herein, a refocusing method using light-field image is proposed. By calculating the focusing cost at different depths from the object, the imaging plane of the object is determined, and a depth map is constructed based on the position of the object’s imaging plane. Compared with traditional light-field depth estimation, the depth map calculated by this method can significantly improve resolution and does not depend on the number of light-field microlenses. In addition, considering that software algorithms rely on hardware structure, this study develops an imaging hardware that is only 7 cm long based on the second-generation microlens camera’s structure, further validating its important refocusing characteristics. It thereby provides a technical foundation for 3D imaging with a single camera.

故宫地下文物库开建于1986年,年代久,防震问题较为突出。为更好解决库房改造中遇到的困难,结合库房现状,研究提出了一种相对较适宜的防震措施。方案里提供的装置主要由夹头、导杆以及阻尼板组成,构造简单且便于安装。为评估其抗震效果,建立了有限元分析模型,并选取了三条地震波进行时程分析。从结果中发现:故宫库房内的独立储藏柜抗震性能较差,九度罕遇地震作用下,储藏柜摇摆剧烈,甚至发生了倾覆。而采用装置后,组合双柜能通过增大的滑移距离更好地耗散掉地震能量,摇摆幅度均明显降低,最大仅为1.64°(El Centro波)。因此,分析结果验证了装置的抗震有效性。

Pure vapor method shows particular advantages in preparing large-area uniform and conformal perovskite film, which can be applied to manufacture perovskite modules and fully textured perovskite/silicon tandem solar cells(TSCs). Here, we provide details on controlling the vapor-solid reaction to acquire high-quality perovskite films, including precisely adjusting vapor pressure and organic salts component, vapor-solid reaction, and post-annealing perovskite film. By employing the optimized conditions, we obtained highquality perovskite films. Power conversion efficiency(PCE) of the inverted structure device can reach as high as 18.1% with an absorber bandgap of 1.62 eV, among the highest PCE using the vapor technique. Significantly, the large-area perovskite film has uniform crystallinity and coverage on textured silicon. Thus, the pure vapor fabrication method of perovskite films shed light on the application of perovskite solar cells because of the potential in module and tandem solar cells.
