  1. A machine vision based non-contact measuring tool for mensuration in industry and manufacturing

    This thesis report discusses the design, implementation and testing of a non-contact measuring tool based on the principle of stereo photogrammetry. The system uses a pair of CCD video cameras and a frame-grabber in a PC to capture the pair of images this requires. The software on the PC then …

  2. The mensuration of textured surfaces using close-range digital photogrammetry for applications in industry

    The mapping of rock surfaces in the open cast mining industry is of importance in assessing the fragmentation distribution of blasted rock, as well as for the profiling of vertical rock faces. This thesis reports on the development of a close range digital photogrammetric surface measurement system …

  8. An Assessment of the Utility of a Non-Metric Digital Camera for Measuring Standing Trees

    A method is set forth which makes use of a commercially available, non-metric, solid-state matrix camera to capture spatial and spectral data from an individual tree bole that can be used to measure characteristics about the stem. In this study diameters and heights were measured and used to …
