The premier low-cost close-range photogrammetry software systems for fast and accurate image-based 3D measurement and modeling
The iWitness and iWitnessPRO data processing systems can accommodate images taken with frame cameras ranging from consumer-grade point-and-shoot, DSLRs and professional medium format metric cameras. Full-motion video can also be photogrammetrically processed. Moreover, images recorded from both terrestrial and aerial camera platforms can be accommodated, and iWitnessPRO has been optimized to automatically generate digital surface models, ortho-imagery and 3D reality meshes from UAV/drone photography.
iWitnessPRO is capable of fully automatic 3D measurement of targeted objects, and the generation of digital surface models (DSMs), orthoimage maps and reality meshes of untargeted objects and scenes, whereas iWitness finds most application in projects where manual and operator-assisted feature extraction is needed. iWitnessPRO is suited to higher-accuracy engineering measurement, architectural recording, heritage documentation, animation and modeling applications, and to 3D mapping with feature measurement from UAVs/drones. iWitness is an ideal tool for forensic measurement and accident reconstruction from photography captured by first responders at the scene. Both systems are also ideal photogrammetric teaching tools. iWitnessPRO can accommodate automatic orientation of networks of 100s of images, whereas iWitness is generally used for networks of a few 10s of images and has a 40-image limit for dense image matching and DSM generation.
