    Ketteryys avaruusteollisuudessa valottaa ketterien menetelmien käyttöä avaruusteollisuuden hankkeissa. Ennalta määritellyt spesifikaatiot, tiukat laatuvaatimukset ja hajautettu järjestelmäkehitys luovat haasteita ketteryyden ...
  • Depth sensors in augmented reality solutions. Literature review 

    Taskinen, Mika; Lahdenoja, Olli; Säntti, Tero; Jokela, Sami; Lehtonen, Teijo (University of Turku Technical Reports, No.10 — September 2015, 01.10.2015)
    The emergence of depth sensors has made it possible to track – not only monocular cues – but also the actual depth values of the environment. This is especially useful in augmented reality solutions, where the position ...
  • 3D Mesh Simplification. A survey of algorithms and CAD model simplification tests 

    Arvo, Jukka; Euranto, Antti; Järvenpää, Lauri; Lehtonen, Teijo; Knuutila, Timo (University of Turku Technical Reports, No.3 — August 2015, 15.08.2015)
    Simplification of highly detailed CAD models is an important step when CAD models are visualized or by other means utilized in augmented reality applications. Without simplification, CAD models may cause severe ...
