摘要

在云计算中,用户需要通过互联网连接到数据服务器进行文件传输,服务器将数据传输到许多服务器。可以借助空气飞行的机器或车辆被称为飞机。作为喷气发动机向下推力的替代,它利用静态升力或机翼的动态升力来对抗重力的拉力。使用飞机壁板 (AWP) 按钮可以轻松绘制模型中的壁板测量点。使用相关壁板规格在现有节点之间或绘图网格上绘制壁板。该技术旨在根据三维扫描仪收集的局部表面属性,发现和提取有关凹痕、突出物或划痕等不良缺陷的信息。完全光滑表面的缺陷包括表面的凹痕和凸起。要提取图像的特征,可以将图片中的像素数量减少到可控制的大小,这样就可以利用表面特征提取(SFE)技术记录图像中最精彩的部分。其中一些问题是无人机的威胁和复合材料的不易破裂。飞机的内部结构可能已经受损,尽管这无法确定。跑道入侵严重威胁航空安全,因为飞机在机场地面上的运动量会增加,还有其他人为因素。机场跑道和滑行道的电子移动地图通过驾驶舱低头位置的平视显示器显示给飞行员。为确保跑道入侵预防系统中机场场景的安全性,需要一种实用的特征提取方法。沿跑道中心线安装的 AWP-SFE 传感器可检测地表移动目标产生的磁信号,并利用这些信息计算目标的长度,从而纠正所有缺点。在对时域数据进行正则化处理后,目标长度可提取峰值特征。目标特征的区分用于确定不同目标之间的相似性。与时域或频域特征方法相比,建议方法的信号特征更容易识别。实验结果表明,与其他方法相比,建议的 AWP-SE 方法实现了 88.2 % 的高效率、73.3 % 的活跃率、87.8 % 的壁面测量点飞机分析率和 32.3 % 的误差率。

Surface feature extraction method for cloud data of aircraft wall panel measurement points

In the cloud, users need to connect to the data server to perform the file transmission via the Internet, and the Server transmits data to many servers. A machine or vehicle that can fly with the assistance of the air is known as an Aircraft. As an alternative to the downward thrust of jet engines, it uses either static lift or an airfoil's dynamic lift to combat gravity's pull. Drawing wall panel measurement points in the model is easy using the Aircraft Wall Panels (AWP) button. Draw wall panels between existing nodes or on the drawing grid using the relevant wall panel specifications. The technique intends to discover and extract information about undesirable defects such as dents, protrusions, or scratches based on local surface attributes gathered from a 3D scanner. Defects from a perfectly smooth surface include indentations and bumps on the surface. An image's features may be extracted by reducing the number of pixels in the picture to a manageable size so that the most exciting sections of the image can be recorded with Surface Feature Extraction (SFE). Some of the problems are the threat of drones and composite materials that do not break easily in oxymoronic. The aircraft's inner structure may have been damaged, although this is impossible to determine. A runway incursion severely threatens aviation safety because of the rise in aircraft movement on the airport surface and other human factors. An electronic moving map of airport runways and taxiways is shown to the pilot through a head-up display in the cockpit's head-down position. A practical feature extraction approach is required to ensure the safety of the airport scene in runway incursion prevention systems. All the drawbacks are rectified by AWP-SFE sensors installed along the runway centerline to detect magnetic signals generated by surface-moving targets, and this information is utilized to compute the target's length. The target length may extract peak features after regularizing the time domain data. Differentiation of target characteristics is used to determine the similarities between distinct targets. The suggested method's signal characteristics are more easily recognized than time domain or frequency domain feature methods. The experimental results show the proposed method AWP-SE to achieve a high-efficiency ratio of 88.2 %, activity ratio of 73.3 %, Analysis of aircraft in wall plane measurement point of 87.8 % and an error rate of 32.3 % compared to other methods.

期刊介绍: Computational Science is a rapidly growing multi- and interdisciplinary field that uses advanced computing and data analysis to understand and solve complex problems. It has reached a level of predictive capability that now firmly complements the traditional pillars of experimentation and theory. The recent advances in experimental techniques such as detectors, on-line sensor networks and high-resolution imaging techniques, have opened up new windows into physical and biological processes at many levels of detail. The resulting data explosion allows for detailed data driven modeling and simulation. This new discipline in science combines computational thinking, modern computational methods, devices and collateral technologies to address problems far beyond the scope of traditional numerical methods. Computational science typically unifies three distinct elements: • Modeling, Algorithms and Simulations (e.g. numerical and non-numerical, discrete and continuous); • Software developed to solve science (e.g., biological, physical, and social), engineering, medicine, and humanities problems; • Computer and information science that develops and optimizes the advanced system hardware, software, networking, and data management components (e.g. problem solving environments).
