iWitness incorporates advanced digital photogrammetric techniques in an inexpensive, easy-to-use system for 3D coordinate measurement from digital imagery recorded with modern digital cameras, both professional and consumer grade.

- very simple operation supported by automatic processes
- highly rigorous and robust photogrammetric orientation
- efficient and fast 'stitching' of photogrammetric project networks
- quality indicators at all stages of the measurement process along with output of accuracy obtained
- a fully automated process for camera calibration
- graphics capability for network analysis
- export of 3D measurement results in DXF format for CADD analysis
- photo-realistic texturing of 3D models
- generation of 3D curves and edges from 2D curve/line markings in images
- handling complex measurement tasks, with no restrictions on the number of images/measuring points employed
