  1. 1. Machine Learning-Based Prediction Models and Threat Detection for Lane-Keeping Assistance

    Författare :John Dahl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; ADAS; Threat detection; Threat assessment;

    Sammanfattning : Traffic accidents have been an ongoing problem for over a century and many efforts have been made to improve traffic safety. Historically, the focus has been on passive safety with innovations, such as crumpling zones, three-point seat belts, and airbags, that aim to mitigate the impact of collisions. LÄS MER

  3. 2. Key Technologies in Low-cost Integrated Vehicle Navigation Systems

    Författare :Yueming Zhao; Lars E. Sjöberg; Milan Horemuž; Hossein Nahavandchi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; INS; MEMS; error modelling; integration structure; lane detection; camera motion; balance adjustment; sensor array;

    Sammanfattning : Vehicle navigation systems incorporate on-board sensors/signal receivers and provide necessary positioning and guidance information for land, marine, airborne and space vehicles. Among different navigation solutions, the Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. LÄS MER

  4. 3. Nonlinear Filtering Methods in Road Geometry Estimation

    Författare :Maryam Fatemi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Advanced driver assistance systems require information about the traffic scene of which the road geometry is an important part. In this thesis we use nonlinear filtering methods to estimate the shape of the road ahead of a host vehicle by fusing measurements of lane markings obtained from a camera and measurements of moving vehicles and barriers obtained from a radar-camera fusion system.

  5. 4. Deep photometry of galaxies : to see or not to see /Magnus Näslund

    Författare :Magnus Näslund; Nils Bergvall; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi; Astronomy; astronomi;

    Sammanfattning : The edge-on spiral galaxy NGC 4565 and the distant galaxy cluster MS2255.7+2039 have been studied at optical wavelengths with deep photometry using the 2.56 m Nordic Optical Telescope on La Palma.By careful data reductions we traced the surface brightness of NGC 4565 to faint levels.
