Method for reconstructing the real coordinates of an object from its plane image 从物体的平面图像重建其真实坐标的方法
V. Nesterov, V. Mukhin, D. Nesterov
Original method of reconstructing the real coordinates of moving objects from their plane images is presented. The method uses multidimensional test objects whose parameters are measures and which are known with high accuracy. In order to ensure the process of measuring movements in real space a test object must be connected with a real object and mathematical models of images of multicomponent movements of a test object must be formed. The parameters of test objects that are used in the named mathematical models are vectors. Such models are used in the construction of systems of measurement equations the solution of which gives the desired components movements of a moving object in 3D space. The method was experimentally tested on specially created stand.
提出了一种从运动物体的平面图像中重建其真实坐标的原始方法。该方法使用多维测试对象,其参数为度量值,并且具有较高的精度。为了保证在真实空间中测量运动的过程,必须将被测物体与真实物体连接起来,并形成被测物体多分量运动图像的数学模型。在命名的数学模型中使用的测试对象的参数是向量。这些模型用于构建测量方程系统,其解给出运动物体在三维空间中的所需分量运动。在特制的支架上对该方法进行了试验。

Analysis of stable functioning of objects using machine learning 使用机器学习分析对象的稳定功能
V. Klyachkin, D. A. Zhukov, E. Zentsova
Stable functioning of the technical objects is estimated using methods of the statistical process control. However this approach does not always provide the timely detection of violations. It is suggested using machine learning methods for the binary classification of object states (stable or unstable). A program has been developed for calculation in the Matlab environment which allows for analysis of impact of the learning method, classification quality criteria, method of validation set as well as methods of selection of significant indicators on the object’s stable functioning forecast precision. Stable operation of the water treatment management system, stable vibration of the hydraulic unit, machining operation process are taken as examples.
利用统计过程控制的方法估计技术对象的稳定功能。然而,这种方法并不总是能够及时发现违规行为。建议使用机器学习方法对对象状态(稳定或不稳定)进行二元分类。开发了Matlab环境下的计算程序,分析了学习方法、分类质量标准、验证集方法以及重要指标选择方法对对象稳定功能预测精度的影响。以水处理管理系统的稳定运行、液压单元的稳定振动、机加工操作过程为例。

Optimization of urban freight transportation based on evolutionary modelling 基于演化模型的城市货运优化
E. Gladchenko, O. Saprykin, A. Tikhonov
Logistics problems require special attention, because every year they become more complicated and multivariable. On the one hand, a supply chain management includes incessant monitoring of such issues as requests elaboration, paths determination, routing of shipments, multimodal choice, set up of transhipments, fleet choice and maintenance, warehousing, packaging and others. On the other hand, dozens of people are involved in the logistics process. All these moments complicate the decision-making that is why data driven decisions are required nowadays. As well as shipment problems are NP-hard, the heuristic methods should be applied to resolve them. In this article we propose a genetic algorithm to solve the complex problem that consists of the Travelling Salesman Problem combined with the Knapsack Problem. We have developed an urban freight transportation model which is focused on the minimization of the underway time as well as on the maximization of the truck’s loading. A significant contribution in our method is the census of traffic frequency by using traffic zoning. The developed approach has been implemented using the Python programming language in the Zeppelin environment. The first version of the system has been approved in the city of Samara (Russia) with test demand dataset.
物流问题需要特别关注,因为它们每年都变得更加复杂和多变量。一方面,供应链管理包括不间断的监控,如要求的阐述、路径的确定、运输路线、多式联运的选择、转运的建立、车队的选择和维护、仓储、包装等。另一方面,数十人参与物流过程。所有这些时刻都使决策复杂化,这就是为什么现在需要数据驱动的决策。由于装运问题是np困难的,因此应采用启发式方法来解决这些问题。在本文中,我们提出了一种遗传算法来解决由旅行商问题和背包问题组成的复杂问题。我们开发了一个城市货运模型,该模型的重点是最小化航行时间和最大化卡车装载。该方法的一个重要贡献是使用交通区划对交通频率进行普查。所开发的方法已经在齐柏林飞艇环境中使用Python编程语言实现。该系统的第一个版本已在萨马拉市(俄罗斯)获得批准,并带有测试需求数据集。

Using the cluster "Sergey Korolev" for modelling computer networks 使用“Sergey Korolev”集群对计算机网络进行建模
D. Y. Polukarov, A. P. Bogdan
Modelling large-scale networks requires significant computational resources on a computer that produces a simulation. Moreover, the complexity of the calculations increases nonlinearly with increasing volume of the simulated network. On the other hand, cluster computing has gained considerable popularity recently. The idea of using cluster computing structures for modelling computer networks arises naturally. This paper describes the creation of software which combines an interactive mode of operation, including a graphical user interface for the OMNeT++ environment, with a batch mode of operation more natural to the high-performance cluster, "Sergey Korolev". The architecture of such a solution is developed. An example of using this approach is also given.

Distributed image processing based on the same IP-cores in FPGA-architecture fpga架构下基于相同ip核的分布式图像处理
V. Zakharov, S. Shalagin, B. F. Eminov
The problem of processing images, i. e., two-dimensional data arrays, was solved through implementing two-dimensional fast Fourier transform (FFT) when using single-type hardware modules – IP-cores in the Virtex-6 FPGA architecture. We have shown the possibility of the parallel implementation of each stage in the two-dimensional FFT, based on four “butterfly”-type transforms (BTr) over four elements of the data array being processed. Estimations were obtained regarding time- and hardware complexity of the IPcore implementing BTrs and used in implementing the one-dimensional FFT. The results obtained can be used in estimating hardware and time consumption when performing a twodimensional FFT over an array of the pre-defined dimensionality in using existing and forthcoming distributed programmable-architecture systems.
在Virtex-6 FPGA架构中,采用单类型硬件模块ip核实现二维快速傅里叶变换(FFT),解决了图像处理即二维数据阵列的问题。我们已经展示了二维FFT中每个阶段并行实现的可能性,基于正在处理的数据数组的四个元素上的四个“蝴蝶”型变换(BTr)。对实现BTrs的IPcore的时间复杂度和硬件复杂度进行了估计,并用于实现一维FFT。所获得的结果可用于在使用现有和即将出现的分布式可编程体系结构系统的预定义维数阵列上执行二维FFT时估计硬件和时间消耗。

The paper discusses the issue of creating an intelligent diagnostic system for welded joints based on the radiographic method. This will speed up the process of decoding radiographic images and reduce the number of errors associated with human factors, since at this time most of the work on decoding images is done manually. The goal of the work is to develop an intelligent system for finding defects in a welded joint in a radiographic image using neural networks. The obtained results are the algorithm of operation of the intelligent diagnostic system for welded joints based on the radiographic method, a trained neural network for detecting defects of welded joints.

Orbital angular momentum acoustic modes demultiplexing by machine learning methods 基于机器学习方法的轨道角动量声模解复用
D. Stankevich
Orbital angular momentum (OAM) multiplexing is a promising method for MIMO multiplexing strategy. OAM multiplexing has previously been demonstrated for underwater acoustic communication, where data transmission was carried out within a single acoustic beam. Inner-product method is most often used for OAM demultiplexing, but it is sensitive to changes of signal parameters. For example, parameters changes can be associated with wave propagation through heterogeneous medium. I propose and demonstrate an approach using of machine learning methods to increase demultiplexing accuracy to 96% for non-stationary signals. In article presents experimental and numerical investigation results of proposed method.
轨道角动量复用是一种很有前途的MIMO复用策略。OAM多路复用先前已被证明用于水声通信,其中数据传输在单个声波束内进行。内积法是OAM解复用最常用的方法,但它对信号参数的变化很敏感。例如,参数变化可能与波在非均质介质中的传播有关。我提出并演示了一种使用机器学习方法将非平稳信号的解复用精度提高到96%的方法。文中给出了该方法的实验和数值研究结果。

Optimal filtering of multidimensional random fields generated by autoregressions with multiple roots of characteristic equations 特征方程多根自回归产生的多维随机场的最优滤波
N. Andriyanov, K. Vasiliev
The use of mathematical models allows to compare the theoretical expressions and simulation results. Autoregressive random fields can be used for description of the images, however, such models have pronounced anisotropy, and the simulated images are too sharp. The elimination of this drawback is possible through the use of models with multiple roots of characteristic equations. The analysis shows that using models with multiple roots in filtering images with smoothly varying brightness provides smaller errors than the use of autoregressive random fields. However, studies of the dependences of filtering efficiency on various model parameters and signal-to-noise ratios for multidimensional autoregressive random fields were almost not carried out. The article discusses the solution of the problem of optimal filtering of images based on models with multiple roots of characteristic equations. Theoretical dependences of the relative variance of the filtering error on the dimension of random fields are obtained. Furthermore, it was presented some results of filtering real images by such model in comparison with autoregressive model.
利用数学模型可以比较理论表达式和仿真结果。自回归随机场可以用于图像的描述,但这种模型具有明显的各向异性,并且模拟的图像过于清晰。通过使用具有特征方程多重根的模型,可以消除这一缺点。分析表明,在平滑变化亮度的图像中,使用多根模型比使用自回归随机场的误差更小。然而,对于多维自回归随机场的滤波效率与各种模型参数和信噪比的关系的研究几乎没有进行。本文讨论了基于特征方程多根模型的图像最优滤波问题的解决方法。得到了滤波误差相对方差与随机场维数的理论依赖关系。并与自回归模型进行了比较,给出了该模型对真实图像的滤波效果。

A method of iterative image normalization for tasks of visual navigation of UAVs 针对无人机视觉导航任务的迭代图像归一化方法
M. Elantcev, I. Arkhipov, R. Gafarov
The work deals with a method of eliminating the perspective distortion of an image acquired from an unmanned aerial vehicle (UAV) camera in order to transform it to match the parameters of the satellite image. The normalization is performed in one of the two ways. The first variant consists in the calculation of an image transformation matrix based on the camera position and orientation. The second variant is based on matching the current frame with the previous one. The matching results in the shift, rotation, and scale parameters that are used to obtain an initial set of pairs of corresponding keypoints. From this set four pairs are selected to calculate the perspective transformation matrix. This matrix is in turn used to obtain a new set of pairs of corresponding keypoints. The process is repeated while the number of the pairs in the new set exceeds the number in the current one. The accumulated transformation matrix is then multiplied by the transformation matrix obtained during the normalization of the previous frame.

本文研究了一种消除从无人机(UAV)相机获取的图像的视角畸变的方法,以便对其进行变换以匹配卫星图像的参数。归一化以两种方式之一执行。第一种变型包括基于摄像机位置和方向的图像变换矩阵的计算。第二种变体基于当前帧与前一帧的匹配。匹配的结果是移位、旋转和缩放参数,这些参数用于获得一组初始的对应关键点对。从这个集合中选择四对来计算透视变换矩阵。然后使用这个矩阵来获得一组新的对应关键点对。当新集合中的配对数量超过当前集合中的配对数量时,重复此过程。然后将累积的变换矩阵与前一帧归一化过程中得到的变换矩阵相乘。最后给出了该方法的实验结果,表明该方法可以在较低的计算成本下提高视觉导航系统的精度。

The normalization is performed in one of the two ways. The first variant consists in the calculation of an image transformation matrix based on the camera position and orientation. The second variant is based on matching the current frame with the previous one. The matching results in the shift, rotation, and scale parameters that are used to obtain an initial set of pairs of corresponding keypoints. From this set four pairs are selected to calculate the perspective transformation matrix. This matrix is in turn used to obtain a new set of pairs of corresponding keypoints. The process is repeated while the number of the pairs in the new set exceeds the number in the current one. The accumulated transformation matrix is then multiplied by the transformation matrix obtained during the normalization of the previous frame.
