  • Differential Geometry, Surface Patches and Convergence Methods 

    Unknown author (1979-02-01)
    The problem of constructing a surface from the information provided by the Marr-Poggio theory of human stereo vision is investigated. It is argued that not only does this theory provide explicit boundary conditions at ...

  • Location Recognition Using Stereo Vision 

    Unknown author (1989-10-01)
    A mobile robot must be able to determine its own position in the world. To support truly autonomous navigation, we present a system that builds and maintains its own models of world locations and uses these models to ...

  • Qualitative Depth and Shape from Stereo, in Agreement with Psychophysical Evidendence 

    Unknown author (1987-12-01)
    Obtaining exact depth from binocular disparities is hard if camera calibration is needed. We will show that qualitative depth information can be obtained from stereo disparities with almost no computations and with ...

  • Self Calibration of Motion and Stereo Vision for Mobile RobotsNavigation 

    Unknown author (1987-08-01)
    We report on experiments with a mobile robot using one vision process (forward motion vision) to calibrate another (stereo vision) without resorting to any external units of measurement. Both are calibrated to a velocity ...

  • Why Stereo Vision is Not Always About 3D Reconstruction 

    Unknown author (1993-07-01)
    It is commonly assumed that the goal of stereovision is computing explicit 3D scene reconstructions. We show that very accurate camera calibration is needed to support this, and that such accurate calibration is difficult ...
