Photometrix is the Australian-based division of Geodetic Systems Inc. (GSI) and offers software systems and consulting services in digital close-range photogrammetric measurement. Whereas GSI specializes in the provision of comprehensive, high-accuracy automated systems for industrial measurement, Photometrix develops photogrammetric software packages designed for use with commercial off-the-shelf cameras, for low- to medium-accuracy measurement. Typical application areas are traffic accident reconstruction, forensic measurement, heritage recording in archaeology, architecture and building, bio-medicine, civil engineering construction and general 3D object reconstruction in industries as diverse as education and animation.
Software systems produced by Photometrix include the internationally acclaimed iWitness and iWitness PRO, Australis and CameraCalibrator. These inexpensive systems incorporate advanced digital photogrammetric techniques and maximum ease of use for 3D coordinate measurement, dense point cloud and digital surface model generation, and the creation of reality meshes and orthoimage mosaics from digital imagery recorded with both professional and consumer-grade digital cameras, from terrestrial and UAV/drone platforms.
General features of iWitness, iWitnessPRO and Australis include:
The Camera Calibrator automatically calibrates both consumer-grade and professional digital cameras through the use of both targetless and coded target approaches. A full calibration of interior orientation (intrinsic parameters) and lens distortion can be obtained within 5 minutes!
