Features - iWitness and iWitnessPRO
iWitnessPRO is a fully automatic image-based measurement system that provides low-cost, extremely fast, high accuracy 3D modeling.
iWitnessPRO is the industry first (and only) fully automatic measurement sytem capable of measuring RGB (color) images using red retroreflective coded target technology.
Red Codes are used as feature point targets via "Construction Point Offset" functionality in iWitnessPRO
Use red codes for measured feature points in your project requiring sub-millemeter accuracy. Traditional manual point referencing, and use of signalized targets can also be measured in the same project network.
iWitnessPRO automatically links up to 12 networks via common LINKER CODES, shared between each "linked" networks, using codes 166-299
Image hundreds for images and iWitnessPRO will automatically ink them into the same (common) XYZ coordinate system so that the entire project is exported to CAD as one DXF file.
Support for measuring almost a quantity of 1000 red codes (1 to 981)
iWitnessPRO can measuring hundreds of red reflective coded targets in the same project network. Further, the same codes can be recycled in numerous projects to support complex measurement scenes, e.g. forensic crime scenes is just one example.
Industry first: Zoom-dependent (Z-D) calibration (iWitnessPRO)
iWitness' image-based measurement features have proven to be the optimal choice in accident reconstruction and forensic investigations.
Powerful photogrammetric orientation processes
This is the value and power of iWitness and iWitnessPRO. Its automated photogrammetric image orientation and positioning are unsurpassed in any other turnkey, low-cost software system.
Automatic camera calibrations made simple and fast
Generation of Polylines and Texture Extractions.
An intuitive user interface
Efficient and fast project "stitching" of photogrammetric networks
A graphics capability for network analysis and export of 3D measurement results in DXF format for CAD analysis
The iWitness "3D Viewer" allows the user to view the model, to measure, and to perform various geometric analysis functions within the interactive viewer. If further CAD analysis is desired, a user can export the model in DXF format.
ZARAF: Zaraf carries out the photogrammetric interior orientation function on scanned photographic prints or slides to enable their use in iWitness. The program generates transformed, resampled digital images from the scanned images for direct import into iWitness. These generated images are then treated as though they were recorded with a digital camera. ZARAF.exe is available in iWitness Version 1.5 and iWitnessPRO V1.0.
FOOM: The Focal length FrOm One IMage process involves marking points in a single image which correspond to object points in the photographed scene that have known 3D coordinates. By this method, the necessary camera focal length and lens distortion information for photogrammetric processing in iWitness can be obtained from a single image from an unknown camera.

XYRectify: The function of XYRectify is to create rectified images of planar surfaces from oblique images. The rectified images can then be treated as scale-homogeneous 2D maps and they thus support the measurement of XY coordinates within the rectification plane. This allows, for example, accuracy measurements of positions on a roadway from oblique photographs, or measurements on a building façade from street level images. XYRectify is available in iWitnessPRO V1.0
