Co-design of architectures and algorithms for mobile robot localization and model-based detection of obstacles / Kodizajn arhitekture i algoritama za lokalizacijumobilnih robota i detekciju prepreka baziranih namodelu

Tertei Daniel 02 December 2016 (has links)
<p>This thesis proposes SoPC (System on a Programmable<br />Chip) architectures for efficient embedding of vison-based<br />localization and obstacle detection tasks in a navigational<br />pipeline on autonomous mobile robots. The obtained<br />results are equivalent or better in comparison to state-ofthe-<br />art. For localization, an efficient hardware architecture<br />that supports EKF-SLAM&#39;s local map management with<br />seven-dimensional landmarks in real time is developed.<br />For obstacle detection a novel method of object<br />recognition is proposed - detection by identification<br />framework based on single detection window scale. This<br />framework allows adequate algorithmic precision and<br />execution speeds on embedded hardware platforms.</p> / <p>Ova teza bavi se dizajnom SoPC (engl. System on a<br />Programmable Chip) arhitektura i algoritama za efikasnu<br />implementaciju zadataka lokalizacije i detekcije prepreka<br />baziranih na viziji u kontekstu autonomne robotske<br />navigacije. Za lokalizaciju, razvijena je efikasna<br />računarska arhitektura za EKF-SLAM algoritam, koja<br />podržava skladi&scaron;tenje i obradu sedmodimenzionalnih<br />orijentira lokalne mape u realnom vremenu. Za detekciju<br />prepreka je predložena nova metoda prepoznavanja<br />objekata u slici putem prozora detekcije fiksne<br />dimenzije, koja omogućava veću brzinu izvr&scaron;avanja<br />algoritma detekcije na namenskim računarskim<br />platformama.</p>
