Conference Paper
Full-text available
In this paper, we describe an infrared imaging payload for a 12U nanosatellite. It contains a cryocooled MWIR detector and FPGA-based data processing unit. The system performs background mon-itoring in spectral bands with low atmospheric transmission. At the core of the system, a modern FPGA System-on-chip provides the computational performance, in...
Conference Paper
Full-text available
Fluctuations of video quality over time can have a significant influence on the overall perceived quality as represented by the QoE. Existing methodologies for subjective video quality assessment, however, are often not suitable for the evaluation of these quality fluctuations, especially if they occur within very small time frames. In this contrib...
Conference Paper
Full-text available
In previous publications it has been shown that no-reference video quality metrics based on a data analysis approach rather than on modeling the human visual system lead to very promising results and outperform many well-known full-reference metrics. Furthermore, the results improve when taking the temporal structure of the video sequence into acco...
Conference Paper
Full-text available
Testing of complex systems is usually elaborate and time-consuming. Nevertheless, extensive funtional end-to-end testing is one of the key factors for success of small satellite projects. Automation can play a dominant role to foster agile engineering techniques in the Newspace domain such as continuous testing in rapid development, integration and...
Conference Paper
Full-text available
One of the emerging technologies in recent years is additive manufacturing. It promises unprecedented design freedom in both modeling and rapid manufacturing. We are reaping the benefits of additive manufacturing for our 12U nanosatellite ERNST by printing the optical bench that supports the spacecraft payloads. We design the structures by using a...
Conference Paper
Fraunhofer EMI is currently designing and building a 12U nanosatellite based on CubeSat technology with an advanced MWIR imaging payload. The mission is called ERNST (Experimental Spacecraft based on Nanosatellite Technology) and its main goal is to evaluate the utility of a nanosatellite mission for scientific and military purposes. Following the...
Conference Paper
Effective sensor technology for space based early warning and detection is a key component in the defense against immediate threats. These sensors have to be designed and optimized based on realistic infrared signatures of both, background (atmospheric, terrestrial) and rocket exhaust plume (or: ballistic missile exhaust plume). In both cases, the...

Conference Paper
Full-text available
In this paper, the results of distributed strain measurements inside the foundation slab of a high-rise building are presented. Optical fibers that have been embedded directly into the concrete by attaching them to the reinforcement are used as sensors. The measurements were obtained using a measurement system that is based on Rayleigh scattering a...
Conference Paper
Structural health monitoring systems on the one side and solutions for building management and automation, including safety and security, on the other side are currently treated as separate systems. Both systems rely on input from sensor data while measuring completely different physical parameters. In this paper, a novel approach for sensor data m...

Video quality evaluation with subjective testing is both time consuming and expensive. An interesting new approach to traditional testing is the so-called crowdsourcing, moving the testing effort into the internet. The QualityCrowd framework allows codec independent, crowd-based video quality assessment with a simple web interface, usable with comm...

Video quality assessment with subjective testing is both time consuming and expensive. An interesting new approach to traditional testing is the so-called crowdsourcing, moving the testing effort into the internet. We therefore propose in this contribution the QualityCrowd framework to effortlessly perform subjective quality assessment with crowdso...
Technical Report
Full-text available
Despite continuing research on the development of better quality metrics, subjective tests are still indispensable for the assessment of video quality. These tests are both time-consuming and expensive and require installing a suitable laboratory that fulfills the corresponding ITU recommendations. In this thesis the use of crowdsourcing in conjunc...
