Natural disasters can cause severe damages to civil infrastructure and lead extensive economic losses casualties. To improve the emergency response capability of under extreme circumstances such as natural human-caused hazards, intelligent technology for management has been extensively studied. As an emerging paradigm interdisciplinary convergence, digital twins (DTs) integrate into different stages provide a new solution (EMCI). However, applications DT in EMCI have several limitations are mostly case by case. sector needs more generalisable lessons address greater value context EMCI. this gap, we first carry out systematic literature review analyse latest progress previous research deficiencies taking scientometrical approach. Next, framework is proposed explain how be applied mitigation, preparation, response, recovery Lastly, trends prospects discussed. Overall, knowledge gained from study will promote development more-viable DTs sector’s demand management.

In-flight system failure is one of the major safety concerns in operation unmanned aerial vehicles (UAVs) urban environments. To address this concern, a framework consisting following three main tasks can be utilized: (1) Monitoring health UAV and detecting failures, (2) Finding potential safe landing spots case critical detected step 1, (3) Steering to spot found 2. In paper, we specifically look at second task, where investigate feasibility utilizing object detection methods suffers an in-flight failure. Particularly, different versions YOLO objection method compare their performances for specific application location that has suffered We performance YOLOv3, YOLOv4, YOLOv5l while training them by large image dataset called DOTA Personal Computer (PC) also Companion (CC). plan use chosen algorithm on CC attached UAV, PC used verify trends see between algorithms CC. confirm these effective emergency report accuracy speed application. Our investigation shows outperforms YOLOv4 YOLOv3 terms maintaining slightly slower inference speed.

Owing to effective and flexible data acquisition, unmanned aerial vehicle (UAV) has recently become a hotspot across the fields of computer vision (CV) remote sensing (RS). Inspired by recent success deep learning (DL), many advanced object detection tracking approaches have been widely applied various UAV-related tasks, such as environmental monitoring, precision agriculture, traffic management. This paper provides comprehensive survey on research progress prospects DL-based UAV methods. More specifically, we first outline challenges, statistics existing methods, provide solutions from perspectives models in three topics: image, video, video. Open datasets related UAV-dominated are exhausted, four benchmark employed for performance evaluation using some state-of-the-art Finally, considerations future work discussed summarized. It is expected that this can facilitate those researchers who come field with an overview along thoughts their further developments.

In recent years, UAV remote sensing has gradually attracted the attention of scientific researchers and industry, due to its broad application prospects. It been widely used in agriculture, forestry, mining, other industries. UAVs can be flexibly equipped with various sensors, such as optical, infrared, LIDAR, become an essential observation platform. Based on sensing, obtain many high-resolution images, each pixel being a centimeter or millimeter. The purpose this paper is investigate current applications well aircraft platforms, data types, elements category; processing methods, etc.; study advantages technology, limitations, promising directions that still lack applications. By reviewing papers published field we found research classified into four categories according field: (1) Precision including crop disease observation, yield estimation, environmental observation; (2) Forestry forest identification, disaster (3) Remote power systems; (4) Artificial facilities natural environment. We image (RGB, multi-spectral, hyper-spectral) mainly neural network methods; monitoring, multi-spectral are most studied type data; for LIDAR data, end-to-end method; review examines development process certain fields implementation some predictions made about possible future directions.
