Multimedia Firearms Training System

The goal of the article is to present a novel Multimedia Firearms Training System. The system was developed in order to compensate for major problems of existing shooting training systems. The designed and implemented solution can be characterized by five major advantages: algorithm for automatic geometric calibration, algorithm of photometric recalibration, firearms hit point detection using thermal imaging camera, IR laser spot tracking algorithm for after action review analysis, and implementation of ballistics equations. The combination of the abovementioned advantages in a single multimedia firearms training system creates a comprehensive solution for detecting and tracking of the target point usable for shooting training systems and improving intervention tactics of uniformed services. The introduced algorithms of geometric and photometric recalibration allow the use of economically viable commercially available projectors for systems that require long and intensive use without most of the negative impacts on color mapping of existing multi-projector multimedia shooting range systems. The article presents the results of the developed algorithms and their application in real training systems

Konzeption und Entwicklung einer universellen, kosteneffizienten und unbemannten Flugrettungsplattform

To this day, charities have not been able to provide individual help for people in need. The aim of the thesis was to develop and construct a universal aerial transporter which could be used to support charities in disaster scenarios. The focus was on the technical development based on the results of a feasibility study. The main requirements for the development were in particular: the lowest possible cost for acquisition and maintenance, providing an easy way of reproduction and the ability to control the system using mobile devices. The legal aspects and the collision avoidance were given less priority or were not considered. In order to identify the current capabilities of charities and their actual problems, a survey among different organisations was done. The results suggested the need for a transport solution. As suitable transport solutions already exist for goods of a mass of at least 50 kg and a transport distance of not less than 100 km, this thesis focuses on the development of a solution below that range and mass. Various other research works were considered, and it became obvious that most of the research was not concerned with the individual support in rescue operations. These findings were used to gather the requirements for the solution. Subsequently, a market research was carried out and possible solutions were compared. As it became apparent that there was no suitable solution available, it was decided to develop a new aerial vehicle. To this end every part that was needed and suitable was individually compared and selected. After the transport vehicle had been developed, the system was built. Parts which were not available, especially for the frame and the universal mounting system, were also developed and produced. In order to increase the flight time of the vehicle, materials of a very low mass were used. During the project a prototype of a universal and unmanned aerial vehicle was successfully developed and constructed. For the transport of different types of goods two different types of universal payload mounting systems were designed. The latter was capable of holding goods with a mass of up to 5 kg. The system allows control of the vehicle in a very convenient way using a mobile device like a smartphone or a tablet. No regular remote control was needed, though still being supported by the system. By means of an android application missions could be created and transmitted wirelessly to the vehicle. After the transmission the system performed the mission autonomously. Due to an insufficient stiffness of the frame, a longer flight test is still outstanding. The automatic release of the payload at the destination required an adjustment of the used application or at least a regular radio control in range. The servo motors used for the mounting system tended to yaw their arms and also required a permanent power supply. Further developments should review the use of alternative motors for the mounting system.Hilfsorganisationen waren bisher nicht in der Lage, Menschen in Notsituationen individuell zu helfen. Das Ziel der Arbeit war daher, die Entwicklung und den Bau eines universellen Flugsystems zum Transport von Lasten, welches in der Lage ist, Hilfsorganisationen in Katastrophenszenarien zu unterstützen. Der Fokus lag dabei auf der Entwicklung einer technischen Lösung in Anlehnung an eine Machbarkeitsstudie. Bei der Entwicklung wurde vor allen Dingen auf möglichst niedrige Anschaffungs- und Wartungskosten, eine leichte Reproduzierbarkeit und die Möglichkeit einer sehr einfachen Steuerung geachtet. Rechtliche und Zulassungsaspekte wurden nur am Rande berücksichtigt. Ein System zur Kollisionsverhütung war nicht Bestandteil der Arbeit. Um herauszufinden, was die aktuellen Möglichkeiten und Probleme von Hilfsorganisationen sind, wurde eine Umfrage unter vielen großen Hilfsorganisationen durchgeführt. Diese sorgte dafür, dass sich die Notwendigkeit einer Transportlösung herauskristallisierte. Da die aktuelle Versorgung mit Gütern ab 50 kg und über eine Distanz von 100 km bereits sehr gut funktioniert, wurde der Fokus auf die Entwicklung einer Transportlösung unterhalb dieses Bereichs konzentriert. Viele sehr interessante Forschungsarbeiten wurden im Rahmen der Arbeit studiert, führten jedoch zu der Erkenntnis, dass sich die meisten Forschungsarbeiten nicht mit der individuellen Versorgung von Personen in Not beschäftigen. Anschließend wurden aus den gewonnenen Erkenntnissen die Anforderungen für die zu entwickelnde Lösung zusammengetragen. Um die Möglichkeit zur Nutzung einer bestehenden Lösung zu überprüfen, wurde eine Marktrecherche durchgeführt und mögliche Systeme miteinander verglichen. Dies führte zu der Erkenntnis, dass aktuell keine fertige und geeignete Lösung existiert und eine neue entwickelt und gebaut werden musste. Dafür wurden alle benötigten Teile mit aktuell verfügbaren und geeignet scheinenden Teilen verglichen und daraus ein System entwickelt. Teile, welche nicht beschaffbar waren, wurden ebenfalls neu entwickelt und selbst hergestellt. Um eine möglichst lange Flugzeit des Fluggeräts zu erreichen, wurde bei der Entwicklung ein Fokus auf die Verwendung von Leichtbaumaterialien gelegt
