Abstract: Large-scale wires and cables (W&Cs) are the nerves of large and complex electromechanical products vital to their regular operation. The laying process of W&C has been highly dependent on manual work and urgently needs intelligent guidance like augmented reality (AR). However, model registration and occlusion handling based on AR for large-scale W&C laying scenes cannot achieve high-quality results to date because of the lack of texture, the local field of vision, and other characteristics. Therefore, a markerless AR guidance method for large-scale W&C laying is proposed to address this long-lasting problem. First, camera, ultrawideband, and inertial measurement unit sensors are integrated to coarsely register the W&C models based on coordinate transformation and mapping virtual and physical spaces. Then, a local edge matching method is used to register the W&C models based on the coarse one finely. Next, the occlusion relationships of the W&C models are handled based on assembly constraints; the models are anchored in the simultaneous localization and mapping map for visual and continuous guidance. A locomotive W&C laying case study and evaluation results show that this method meets industrial application requirements regarding efficiency, accuracy, and robustness and has several advantages compared to other methods, including extra-large scale, automatic registration, and virtual-real fusion.

Abstract: Industry 5.0 aims at establishing an inclusive, smart and sustainable production process that encourages human creativity and expertise by leveraging enhanced automation and machine intelligence. Collaborative robotics, or "cobotics",is a major enabling technology of Industry 5.0, which aspires at improving human dexterity by elevating robots to extensions of human capabilities and, ultimately, even as team members. A pivotal element that has the potential to operate as an interface for the teaming aspiration of Industry 5.0 is the adoption of novel technologies such as virtual reality (VR), augmented reality (AR), mixed reality (MR) and haptics, together known as "augmentation". Industry 5.0 also benefit from Digital Twins (DTs), which are digital representations of a physical assets that serves as their counterpart - or twins. Another essential component of Industry 5.0 is artificial intelligence (AI), which has the potential to create a more intelligent and efficient manufacturing process. In this study, a systematic review of the state of the art is presented to explore the synergies between cobots, DTs, augmentation, and Industry 5.0 for smart manufacturing. To the best of the author's knowledge, this is the first attempt in the literature to provide a comprehensive review of the synergies between the various components of Industry 5.0. This work aims at increasing the global efforts to realize the large variety of application possibilities offered by Industry 5.0 and to provide an up-to-date reference as a stepping-stone for new research and development within this field.

近期，NASA宇航员将HoloLens AR头显应用在国际空间站中许多场景，除了此前公布的跑步机检修维护外，近期还将它用来维护冷原子实验室。据悉，这是宇航员们首次在AR辅助下维修科学实验设备，未来有望将这项技术用于远程升级冷原子实验室，省去运送回地球的过程。

虚拟现实(VR)是一种可以创建和体验虚拟世界的计算机仿真系统，增强现实(AR)技术是一种将虚拟信息与现实世界巧妙结合的技术。生成的文字、图像、三维模型、音乐、视频等虚拟信息模拟应用到现实世界中，两种信息相互补充，从而实现对现实世界的“增强”。

移动互联网的全面普及和高速发展，虽然打破了信息交互的时间瓶颈和场景瓶颈，但是在人机交互上仍存在着信息可视化和信息即时化的界限。VR/AR技术在通信带宽不断拓展的趋势下，能够有效实现对智能手机的产品更迭，打破信息化的物理界限。
