Human body detection is a fundamental research problem where computer vision could be applied. This research area has wide applications including surveillance, search and rescue missions. Building an effective human body detector framework under wide ranges of weather, lighting and environmental conditions is a challenge task. A variety of sensors and optimisation algorithms are proposed. This paper aims to review the human body detection methodology conducted by the Unmanned Aerial Vehicles (UAV), and the future research for the UAV search and rescue applications.

Maritime Search And Rescue

According to the Convention for the Safety of Life at Sea and International Convention on Maritime Search and Rescue, saving human lives at sea is the duty of all signatory states. This paper analyzes and gives an overview of previous research activities in search and rescue system at sea and how the use of unmanned aerial vehicles (UAV) can improve search and rescue actions at sea. Research activities include development of the search system and placement of resources that are used in search and rescue actions (ships, planes etc.). Previous research is mainly related to minimizing response time when accidents at sea are detected in relation to search and rescue missions. Implementation of unmanned aerial vehicles into the search and rescue system enables improvement of these actions due to earlier detection and verification of accidents at sea and prevents unnecessary search and rescue units engagement in cases when an accident did not occur. The results of previous research point to the fact that future research should aim to explore the synthesis of unmanned aerial vehicles with the existing search and rescue system at sea in Croatia.

The article discusses how an optimal release mechanism was developed taking into account the aerodynamics of one specific mothership and child Unmanned Aerial Vehicle (UAV). Furthermore, it discusses the PID-based control concept that was introduced in order to autonomously stabilise the child UAV after being released from the mothership UAV. Finally, the article demonstrates how the concept of a mothership and child UAV combination could be taken advantage of in the context of a search and rescue operation.</p><p style="margin: 0cm 0cm 0pt;"><span lang="EN-US"><span style="font-family: Calibri; font-size: small;"><br /></span></span></p>

The Voice

<p class="Default">Unmanned Aerial Vehicles have gained well known attention in recent years for a numerous applications such as military, civilian surveillance operations as well as search and rescue missions. The UAVs are not controlled by professional pilots and users have less aviation experience. Therefore it seems to be purposeful to simplify the process of aircraft controlling. The objective is to design, fabricate and implement an unmanned aerial vehicle which is controlled by means of voice recognition. In the proposed system, voice commands are given to the quadcopter to control it autonomously. This system is navigated by the voice input. The control system responds to the voice input by voice recognition process and corresponding algorithms make the motors to run at specified speeds which controls the direction of the quadcopter.</p>

During this last decade, the blockchain (BC) paradigm has been required in several use cases and scenarios in particular for security, privacy, and trust provisioning. Accordingly, several studies proposed the use of BC technology to secure and to assure the trustworthiness of unmanned aerial vehicles (UAVs). In this context, this chapter highlights several applications and scenarios for the deployment of UAVs within diverse smart systems. In addition, it illustrates the advantages of the integration of the BC within UAVs-based smart systems. This integration reveals new challenges and future research directions that are discussed in this chapter.

Valley Area

The paper provides a novel cooperative motion scheme for networked Unmanned Aerial Vehicles (UAVs) to fully sweep-cover a priori unknown elongated areas with curved borders, which are termed “valley areas.” The UAVs’ motion is confined between the borders. Different from former research on straight-corridor-sweep-coverage, in each valley area, the width of different portions varies dramatically: the UAVs need to line up across the valley area to achieve full coverage of the widest portions while they can only pass through the narrowest parts one by one in a queue. The UAVs are provided with barrier detection and inter-UAV communication. According to the scheme, a distributed control law has been offered for discrete-time multi-UAV systems, guaranteeing crash avoidance and full coverage while considering the constrained mobility of the UAVs. Regular and extreme simulations are carried out to verify the efficacy and stability of the proposed algorithm. Solutions to U-shaped valley coverage and the case of insufficient UAVs available are discussed with validation simulations. Comparison simulations are conducted with respect to a line-sweep-coverage algorithm developed by a closely related work, and differences in performance are revealed subsequently. Conclusions are drawn with possible directions of future research.

The use of robots to map disaster-stricken environments can prevent rescuers from being harmed when exploring an unknown space. In addition, mapping a multi-robot environment can help these teams plan their actions with prior knowledge. The present work proposes the use of multiple unmanned aerial vehicles (UAVs) in the construction of a topological map inspired by the way that bees build their hives. A UAV can map a honeycomb only if it is adjacent to a known one. Different metrics to choose the honeycomb to be explored were applied. At the same time, as UAVs scan honeycomb adjacencies, RGB-D and thermal sensors capture other data types, and then generate a 3D view of the space and images of spaces where there may be fire spots, respectively. Simulations in different environments showed that the choice of metric and variation in the number of UAVs influence the number of performed displacements in the environment, consequently affecting exploration time and energy use.

Unmanned Aerial Vehicles (UAVs) have recently been used in a wide variety of applications due to their versatility, reduced cost, rapid deployment, among other advantages. Search and Rescue (SAR) is one of the most prominent areas for the employment of UAVs in place of a manned mission, especially because of its limitations on the costs, human resources, and mental and perception of the human operators. In this work, a real-time path-planning solution using multiple cooperative UAVs for SAR missions is proposed. The technique of Particle Swarm Optimization is used to solve a Model Predictive Control (MPC) problem that aims to perform search in a given area of interest, following the directive of international standards of SAR. A coordinated turn kinematic model for level flight in the presence of wind is included in the MPC. The solution is fully implemented to be embedded in the UAV on-board computer with DUNE, an on-board navigation software. The performance is evaluated using Ardupilot’s Software-In-The-Loop with JSBSim flight dynamics model simulations. Results show that, when employing three UAVs, the group reaches 50% Probability of Success 2.35 times faster than when a single UAV is employed.

The paper considers new approaches to the use of unmanned aerial vehicles (UAVs) and associated technologies of emergency warning under extreme conditions of the northern climatic zones for expanding the search and rescue capabilities in case of the forced landing of the descent module (DM). The paper also analyzes the innovative solutions on the human protection against adverse environmental effects and the means for emergency medical care that are delivered to the landing place of the descent module and allow mitigating risks for surviving under unfavorable climatic conditions prior the evacuation operations begin.
