Take the Field from your Smartphone: Leveraging UAVs for Event Filming (original) (raw)

An Unmanned Aerial Vehicle Network for Sport Event Filming with Communication Constraints

2020

In this paper, event coverage, specifically Sport Event Filming (SEF) with communication constraints is formulated. A team of UAVs need to position themselves and plan their paths over a limited area to track the movements (e.g., of the ball) in a gaming field and deliver high quality and timely stream of the events (e.g., ball passes, goals) to the event spectators meeting certain satisfaction criteria. Assuming the goal of maximizing the viewer’s satisfaction, a set of distributed schemes to the UAV movement problem are proposed. They are based on Artificial Potential functions and possess no a-priori knowledge of the sequence of game actions. Extensive simulations are used to analyze the performance in terms of viewer’s satisfaction, cost, and networking performance and show that the proposed schemes outperform previous schemes.

Filming Sport Events with Mobile Camera Drones: Mathematical Modeling and Algorithms

Abstract—We introduce and formulate the Sport Event Filming (SEF) problem. We are interested in controlling the movement of a set of camera drones filming the event by moving over the field where the event takes place. The objective of the formulation is to maximize the satisfaction of event viewers and/or minimize the distance traveled by the camera-drones.

In this paper, we introduce two families of distributed algorithms to control the movement of groups of flying robots that are monitoring an event by moving over the field where the event takes place, while optimizing some specific objective. In order to show the effectiveness of our algorithms, we formulate the Sport Event Filming (SEF) problem. The objective of the problem is to maximize the satisfaction of event viewers while minimizing the distance traveled by the camera-drones. We propose two families of solutions to solve the dynamic version of the problem, where the flying robots do not have any knowledge of the input sequence and move in reaction to the movements of the protagonists of the event. The first family (Nearest Neighbor) is based on a technique used in robotic systems, whereas the second family (Ball Movement Interception) is designed based on specific characteristics of the SEF problem. We present extensive simulation results for both families in terms of average viewer satisfaction and traveled distance for the flying robots, when several parameters vary.

Cooperative UAV Scheme for Enhancing Video Transmission and Global Network Energy Efficiency

Sensors

Collaboration between multiple Unmanned Aerial Vehicles (UAVs) to set up a Flying Ad Hoc Network (FANET) is a growing trend since future applications claim for more autonomous and rapid deployable systems. The user experience on watching videos transmitted over FANETs should always be satisfactory even under influence of topology changes caused by the energy consumption of UAVs. In addition, the FANET must keep the UAVs cooperating as much as possible during a mission. However, one of the main challenges in FANET is how to mitigate the impact of limited energy resources of UAVs on the FANET operation in order to monitor the environment for a long period of time. In this sense, UAV replacement is required in order to avoid the premature death of nodes, network disconnections, route failures, void areas, and low-quality video transmissions. In addition, decision-making must take into account energy consumption associated with UAV movements, since they are generally quite energy-intens...

Use of FPV Drones for Sports Documentaries

KnE Social Sciences

The role of a cameraman is crucial for creating unique camera movements and to implement good visual force in sports documentaries. FPV drones allow for the greatest immersion through camera movements. Drone operators depict the visual awareness of sports from inside a flying machine that, like an athlete, moves swiftly and accurately. This research used a qualitative approach. Data collection was carried out through studying literature related to sports documentation work. FPV videos are often shown at various professional sporting events, such as at the Red Bull Rampage, an annual extreme mountain bike freestyle competition with a natural track free of synthetic elements or special markings and with only one start and finish line. Based on the analysis of camera movements such as panorama, tracking, titration and crab in the video documentary Redbull Rampage 2021, it was concluded that every movement of the camera plays a diverse role. Camera movement techniques can affect the dra...

IJERT-Wireless Networking For Live Video Broadcasting: Video Compression And Cost Optimization

These events happens everyday at local levels like schools and colleges. But these are related to small groups of viewers, for such live video broadcasting the broadcasting equipments ,crew of technicians and producers requires a large amount of cost which does not justify the non popularity of such events. Wireless Networking faces many challenges in terms of providing Live Video Broadcasting at low-cost also the quality level should be maintained. Basically in this paper we present how the video analysis can be used to detect relative locations of players, zooming factors, focus, different views and angles also the automated nature of this system minimizes the human involvement in production of video contents and hence reduces the production cost. The deployment of the Wireless microcasting is HD videos this can be done with the help of video encoders. Live video broadcasting can be done by using the wireless technique at a low cost compared with the current streaming solutions.

Ensuring network connectivity of UAV’s performing video reconnaissance

2008

Abstract Current and emerging military missions require image-feedback from camera-equipped assets. Motivated by mission scenarios and sensor restrictions, operations may require the collaboration of assets over an ad-hoc network. The development in this paper represents the first efforts to examine the problem of balancing tradeoffs between asset/sensor cone positioning to satisfy mission requirements and network requirements such as maintaining network connectivity.

Efficient Deployment of Multi-UAVs in Massively Crowded Events

Sensors, 2018

In this paper, the efficient 3D placement of UAV as an aerial base station in providing wireless coverage for users in a small and large coverage area is investigated. In the case of providing wireless coverage for outdoor and indoor users in a small area, the Particle Swarm Optimization (PSO) and K-means with Ternary Search (KTS) algorithms are invoked to find an efficient 3D location of a single UAV with the objective of minimizing its required transmit power. It was observed that a single UAV at the 3D location found using the PSO algorithm requires less transmit power, by a factor of 1/5 compared to that when using the KTS algorithm. In the case of providing wireless coverage for users in three different shapes of a large coverage area, namely square, rectangle and circular regions, the problems of finding an efficient placement of multiple UAVs equipped with a directional antenna are formulated with the objective to maximize the coverage area and coverage density using the Circ...
