  • 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 ...
  • Advantages of 3D time-of-flight range imaging cameras in machine vision applications

    Dorrington, Adrian A.; Kelly, Cameron B.D.; McClure, Shane H.; Payne, Andrew D.; Cree, Michael J. (Electronics Research, 2009)
    Machine vision using image processing of traditional intensity images is in wide spread use. In many situations environmental conditions or object colours or shades cannot be controlled, leading to difficulties in correctly ...
  • Analysis of binning of normals for spherical harmonic cross-correlation

    Larkins, Robert L.; Cree, Michael J.; Dorrington, Adrian A. (Society of Photo-Optical Instrumentation Engineers, 2012)
    Spherical harmonic cross-correlation is a robust registration technique that uses the normals of two overlapping point clouds to bring them into coarse rotational alignment. This registration technique however has a high ...
  • Analysis of ICP variants for the registration of partially overlapping time-of-flight range images

    Larkins, Robert L.; Cree, Michael J.; Dorrington, Adrian A. (IEEE, 2010)
    The iterative closest point (ICP) algorithm is one of the most commonly used methods for registering partially overlapping range images. Nevertheless, this algorithm was not originally designed for this task, and many ...
  • Analysis of the SoftKinetic DepthSense for Range Imaging

    Cree, Michael J.; Streeter, Lee V.; 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 ...
