iWitnessPRO Operational Features & Capabilities

  • Exceptionally intuitive and easy to use, with a minimum of toolbar buttons and pull-down menus and a maximum of rigorous background computational support: a full multi-image 3D measurement may involve no more than left-mouse clicks and five toolbar buttons.
  • Automatic recognition of the digital camera or cameras being employed, either consumer grade or professional; iWitnessPRO maintains a comprehensive database of cameras and calibration information.
  • Photogrammetric orientation processes occur automatically: 3D object point coordinates are updated with every new image point referencing, providing instant measurement results and very robust quality control.
  • Accomodation of very complex image configurations: iWitnessPRO readily handles the orientation of very difficult network geometries.
  • Fully automatic camera calibration, supported either as a stand-alone operation or as an integral component of the object measurement process (self-calibration).
  • Auto-assisted image marking and referencing; single-key centroiding leads to both high-accuracy image marking (to 1/30th pixel) and optimal XYZ coordinate accuracy.
  • Guided Referencing Mode: In the referencing of the third and subsequent images, image point locations are predicted, allowing fast, single-image referencing of feature points.
  • A Review Mode: This allows the accuracy of all image marking and referencing to be assessed, point-by-point, with interactive refinement of referencing, and instantaneous updating of network orientation and 3D point measurements.
  • Texturing of 3D models: Through image rectification to planar facets, full photo-realistic texturing of the 3D object model is available.
  • Generation of 3D curves and edges: 3D Curves and edges can be generated from 2D curve and edge segments marked in the images.
  • Flexibility to interactively set and change the XYZ object coordinate system, assign scale and tie-in to any chosen existing reference frame via control points.
