Vortrag: Map Generation From the sensor to imagery
by LRZ aktuell Feb. 20, 2012

Feb. 20, 2012

Dr. Bernhard Reitinger Montag, 19.03.2012, 14:00-15:30 LRZ, Boltzmannstrasse 1, 85748 Garching, Hoersaal (H.E.009) Abstract: Maps are ubiquitous in our daily lives ranging from navigation and routing to trip planning and virtual tours in the internet. Although navigation maps is common nowadays,the generation requires lots of world class research efforts. This talk will give a tour from the very beginning of the processing chain the digital aerial camera to the very end the map product known as Bing Maps. Different to consumer cameras, the developed aerial sensor captures images with a resolution of 260 MPix per shot every 2 seconds. Algorithms have been developed by our research team which provide an interactive visualization of large amount of image data as well as efficient parallel processing to the final product. Techniques known from Microsoft s PhotoSynth product, but also world class dense matching and ortho generation methods are part of the presented pipeline. Biography: Bernhard Reitinger received his master s degree from the Johannes Kepler University in Linz. In 2005, he finished his PhD at the Technical University in Graz where he was focused on medical visualization within virtual reality environments. After he was working as a post-doc researcher in Graz in the context of augmented reality and computer vision, he was hired by Microsoft in 2007 to lead a research and development team focusing on computer vision and visualization of digital aerial cameras.

Foerdermoeglichkeiten (Personal) im Rahmen von KONWIHR-III
by LRZ aktuell Feb. 14, 2012

Feb. 14, 2012

KONWIHR-III-Foerderprogramm Kompetenznetzwerk fuer wissenschaftliches Hoechstleistungsrechnen in Bayern Simulationssoftware fuer Multi-/Manycore-Systeme Mit dem SuperMUC am LRZ in Garching und dem LiMa-Cluster am RRZE in Erlangen stehen den baye-rischen Wissenschaftlern Hoechstleistungsrechner der obersten Leistungsklassen zur Verfuegung. Die effizi-ente Nutzung dieser hochparallelen Systeme erfor-dert die Anpassung bestehender und die Entwick-lung neuer skalierbarer Simulationsprogramme. Um diese Arbeiten effizient und nachhaltig zu gestalten, muessen moderne Prinzipien des Software Engineering und Performance Engineering eingesetzt werden. Eine enge Kooperation zwischen Anwendungswissen-schaften, Informatik und HPC-Spezialisten ist daher heute die grundlegende Voraussetzung fuer konkur-renzfaehige, hoch parallele Simulationsprogramme. Der aktuelle Wandel hin zu Manycore-Prozessoren sorgt zusaetzlich dafuer, dass diese Anforderungen fuer einen immer breiteren Kreis von Anwendern bis hin zur Nutzung von Desktopsystemen gelten werden. Ziel des Foerderprogramms ist es, Wissenschaftler in Bayern bei der Anpassung und der Neuentwicklung ihrer numerischen Anwendungen fuer moderne, (hoch) parallele Rechnerarchitekturen zu unterstuetzen. Die Projektfoerderung umfasst die Bereitstellung von Per-sonalmitteln und den Zugriff auf die ausgewiesene HPC-Kompetenz der beteiligten Rechenzentren. Foerderfaehige Massnahmen * Folgende typische Aufgabengebiete werden als foerderungsfaehig im Rahmen der vorliegenden Ausschrei-bung erachtet: * Optimierung und Parallelisierung bestehender Simulationsprogramme * Entwicklung und Implementierung neuer paralleler Simulationscodes unter besonderer Beruecksichtigung von Multi- und Manycore-Prozessoren * Evaluierung neuer Rechnerarchitekturen wie GPGPUs oder Intel MIC und Parallelisierungsansaetze (hybrid ?MPI+X?, PGAS) * Entwicklung, Evaluierung und Implementierung neuer numerischer Methoden, unter besonderer Beruecksichtigung der Eigenschaften von Multicore- CPUs * Analyse von Einzelprozessor-Performance, Kommunikationsverhalten und paralleler Skalierung mit professionellen Werkzeugen * Anpassung von Softwarepaketen: Evaluierung geeigneter Rechnersysteme, Compiler, Bibliotheken; Verbesserung von Restart- und I/O-Faehigkeiten; * Integration der Systeme am LRZ oder RRZE in Work-flows * Analyse der verwendeten Loeser und Algorithmen und Test moeglicher Alternativen * Entwicklung energieeffizienter Simulationscodes Antragsverfahren und Foerderumfang Gefoerdert werden Projekte an bayerischen Hochschulen mit einer Dauer von bis zu zwoelf Monaten. Die Foerderung bemisst sich an der Dauer des Vorhabens und kann maximal 50.000 pro Projekt betragen. Die Projekte sind in enger Kooperation mit einem der beiden Rechenzentren durchzufuehren. Insbesondere soll der gefoerderte Projektmitarbeiter einen laengeren Zeitraum (etwa 50% der Projektdauer) an einem der beiden Zentren verbringen und dort seine programm-nahen Arbeiten durchfuehren und dabei direkt auf die Hilfe der dortigen Wissenschaftler zurueckgreifen koennen. Projektantraege koennen in halbjaehrlichem Turnus (jeweils zum 1.3. und 1.9.) bei den beiden KONWIHR-Geschaeftsstellen eingereicht werden. Auf etwa sechs Seiten sollen das Projekt beschrieben und insbesondere die durchzufuehrenden Arbeiten konkret aufgelistet werden. Weiterhin koennen auch kleinere Massnahmen mit einer Laufzeit von bis zu zwei Monaten jederzeit eingereicht werden. Auf etwa zwei Seiten sollen Projektziel und die durch-zufuehrenden Arbeiten kurz beschrieben werden. Es wird erwartet, dass der Projektmitarbeiter die gesamte Foerderdauer an einem der beiden Rechenzentren verbringt. Fuer Antragsteller ausserhalb der Standorte Erlangen und Muenchen/ Garching kann ein Zuschuss zu den Reise- und Aufenthaltskosten gewaehrt werden. Vor der Antragstellung wird eine Kontaktaufnahme mit einem der beiden Rechenzentren dringend empfohlen, damit die Verfuegbarkeit von Mitarbeitern und Spe-zialwissen sichergestellt ist. Antraege sind vom federfuehrenden Wissenschaftler einzureichen und werden von Direktorium und Beirat des KONWIHR-III begutachtet.
