  • Achieving sub-millimetre precision with a solid-state full-field heterodyning range imaging camera

    Dorrington, Adrian A.; Cree, Michael J.; Payne, Andrew D.; Conroy, Richard M.; Carnegie, Dale A. (Institute of Physics Publishing, 2007)
    We have developed a full-field solid-state range imaging system capable of capturing range and intensity data simultaneously for every pixel in a scene with sub-millimetre range precision. The system is based on indirect ...
  • Analysis of the SoftKinetic DepthSense for Range Imaging

    Cree, Michael J.; Streeter, Lee; Conroy, Richard M.; Dorrington, Adrian A. (Springer, 2013)
    We analyse the SoftKinetic DepthSense 325 range imaging camera for precision and accuracy in ranging out to 3 m. Flat planar targets (one a grey board, the other made from retroreflective material) are imaged at a variety ...
  • Heterodyne range imaging as an alternative to photogrammetry

    Dorrington, Adrian A.; Cree, Michael J.; Carnegie, Dale A.; Payne, Andrew D.; Conroy, Richard M. (The Society for Imaging Science and Technology, The International Society for Optical Engineering, 2007)
    Solid-state full-field range imaging technology, capable of determining the distance to objects in a scene simultaneously for every pixel in an image, has recently achieved sub-millimeter distance measurement precision. ...
  • A power-saving modulation technique for time-of-flight range imaging sensors

    Conroy, Richard M.; Dorrington, Adrian A.; Payne, Andrew D.; Künnemeyer, Rainer; Cree, Michael J. (Society of Photo-Optical Instrumentation Engineers, 2011)
    Time-of-flight range imaging cameras measure distance and intensity simultaneously for every pixel in an image. With the continued advancement of the technology, a wide variety of new depth sensing applications are emerging; ...
  • Range imager performance comparison in homodyne and heterodyne operating modes

    Conroy, Richard M.; Dorrington, Adrian A.; Künnemeyer, Rainer; Cree, Michael J. (SPIE and IS&T, 2009)
    Range imaging cameras measure depth simultaneously for every pixel in a given field of view. In most implementations the basic operating principles are the same. A scene is illuminated with an intensity modulated light ...
