  • Analysis of LED arrangement in an array with respect to lens geometry 
    Ley, Peer-Phillip; Held, Marcel Philipp; Lachmayer, Roland (Bellingham, Wash. : SPIE, 2018)
    Highly adaptive light sources such as LED arrays have been surpassing conventional light sources (halogen, xenon) for automotive applications. Individual LED arrangements within the array, high durability and low energy ...
  • Cloud detection based on high resolution stereo pairs of the geostationary meteosat images 
    Dehnavi, Sahar; Maghsoudi, Yasser; Zakšek, Klemen; Zoej, Mohammad Javad Valadan; Seckmeyer, Gunther; Skripachev, Vladimir (Basel : MDPI AG, 2020)
    Due to the considerable impact of clouds on the energy balance in the atmosphere and on the earth surface, they are of great importance for various applications in meteorology or remote sensing. An important aspect of the ...
  • Development of digital aerial cameras 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2010)
    Digital aerial cameras have replaced analogue aerial cameras in several countries. The development for operational aerial photogrammetry started with the line scan camera ADS40, followed by Z/I Imaging DMC and Vexcel Imaging ...
  • Discrete optimization for optical flow 
    Menze, Moritz; Heipke, Christian; Geiger, Andreas (Heidelberg : Springer Verlag, 2015)
    We propose to look at large-displacement optical flow from a discrete point of view. Motivated by the observation that sub-pixel accuracy is easily obtained given pixel-accurate optical flow, we conjecture that computing ...
  • Efficient conceptual design for LED-based pixel light vehicle headlamps 
    Held, Marcel Philipp; Lachmayer, Roland (Bellingham, Wash. : SPIE, 2017)
    High-resolution vehicle headlamps represent a future-oriented technology that can be used to increase traffic safety and driving comfort. As a further development to the current Matrix Beam headlamps, LED-based pixel light ...
  • Efficient ground surface displacement monitoring using Sentinel-1 data: Integrating distributed scatterers (DS) identified using two-sample t-test with persistent scatterers (PS) 
    Shamshiri, Roghayeh; Nahavandchi, Hossein; Motagh, Mahdi; Hooper, Andy (Basel : MDPI AG, 2018)
    Combining persistent scatterers (PS) and distributed scatterers (DS) is important for effective displacement monitoring using time-series of SAR data. However, for large stacks of synthetic aperture radar (SAR) data, the ...
  • On the performance of optical phased array technology for beam steering : effect of pixel limitations 
    Cala’Lesina, Antonio; Goodwill, Dominic; Bernier, Eric; Ramunno, Lora; Berini, Pierre (Washington, DC : OSA - The Optical Society, 2020)
    Optical phased arrays are of strong interest for beam steering in telecom and LIDAR applications. A phased array ideally requires that the field produced by each element in the array (a pixel) is fully controllable in phase ...
  • Radiometric and geometric characteristics of pleiades images 
    Jacobsen, Karsten; Topan, H.; Cam, A.; Özendi, M.; Oruç, M. (Göttingen : Copernicus GmbH, 2014)
    Pleiades images are distributed with 50cm ground sampling distance (GSD) even if the physical resolution for nadir images is just 70cm. By theory this should influence the effective GSD determined by means of point spread ...
  • Road safety enhancement: An investigation on the visibility of on-road image projections using DMD-based pixel light systems 
    Rizvi, Sadiq; Ley, Peer-Phillip; Knöchelmann, Marvin; Lachmayer, Roland (Bellingham, Wash. : SPIE, 2018)
    Research reveals that visual information forms the major portion of the received data for driving. At night -owing to the, sometimes scarcity, sometime inhomogeneity of light- the human physiology and psychology experiences ...
  • Survey of on-road image projection with pixel light systems 
    Rizvi, Sadiq; Knöchelmann, Marvin; Ley, Peer-Phillip; Lachmayer, Roland (Bellingham, Wash. : SPIE, 2017)
    HID, LED and laser-based high resolution automotive headlamps, as of late known as pixel light systems', are at the forefront of the developing technologies paving the way for autonomous driving. In addition to light ...
