Corporate Information

Photometrix offers specialist systems and consulting services in digital close-range photogrammetric measurement. The product line includes the internationally renowned Australis software system for automatic image-based 3D engineering measurement and comprehensive automatic camera calibration; and the inexpensive and easy-to-use iWitness software suite for automated, robust and flexible 3D coordinate measurement in accident reconstruction and forensics, heritage recording and 3D model generation. This suite comprises the Photometrix iWitness, iWitnessPRO and iWitnessPRO-Agilis programs, which are essentially distinguished by the level of automation each supports. Also included in the product line is the inexpensive and widely used CameraCalibrator software for automatic metric calibration of digital cameras, including consumer grade compact, superzoom and DSLR cameras (i.e. Nikon, Canon, Sony) and everything from small format UAVs/drones (i.e. DJI Phantom 3 / 4 / Mavic Pro / Inspire), right up to high-resolution professional medium format cameras (i.e. Phase One, Hasselblad).

Photometrix products

Photometrix Australis Australis :: our flagship automatic close-range photogrammetric 3D coordinate measurement software for both industrial & engineering metrology, and for highest-accuracy metric calibration of digital cameras, including multi-camera clusters.

Photometrix iWitness iWitness V3 :: an inexpensive photogrammetric measurement system optimized for accident reconstruction and forensic photogrammetry, and for manual feature extraction.

Photometrix iWitnessPRO iWitnessPRO V3 :: supports fully automatic photogrammetric network orientation and 3D point measurement of both targeted (red retro reflective targets) and targetless objects and scenes, as well as providing all the features of the classic iWitness software, and more, such as geometric analysis tools and 3D point measurement from single images (monoplotting) and an underlying object point field or digital surface model (DSM). Photogrammetry has never been easier!

Photometrix iWitnessPRO-Agilis iWitnessPRO-Agilis :: is our premier low-cost photogrammetric measurement system. It has all the features of iWitnessPRO, plus the capability of producing fully textured 3D object models through automated network orientation and object reconstruction via the integrated nFrames-produced dense image matching software SURE.  The generation of a DSM, coupled with monoplotting, make this software particularly well suited to 3D feature extraction and terrain modelling from UAV imagery.

Photometrix CameraCalibrator CameraCalibrator :: software to automatically calibrate your camera for optimal photogrammetric accuracy. With the new Version 2 of the CameraCalibrator, the automatic calibration process can be performed with or without targets, the latter being well suited to calibrating cameras operating from UAVs/drones. A full calibration of principal distance and principal point offset (interior orientation, or intrinsic parameters), and radial & decentring distortion of the lens can be obtained within 10 minutes.

Application Study

Photometrix examplePhotometrix iWitnessPRO-Agilis was used to generate a dimensionally accurate and visually stunning 3D reconstruction of a wooden barn, fences, tractor, trailer & surrounding landscape from imagery recorded from a multi-copter UAV flying at 60m above ground. The dense point cloud containing over 12,000,000 points from this project can be viewed interactively on our website. Click here to find out more.

10 Year Anniversary

Photometrix iWitness 10 YearsiWitness recently celebrated its 10th anniversary. Over the past decade this inexpensive and easy-to-use software system for close range photogrammetry has been adopted by a broad range of users, especially in the areas of accident reconstruction and forensic measurement. iWitness is used by hundreds of police departments around the globe, as well as in cultural heritage documentation, architectural and engineering measurement, and general 3D modelling applications. This powerful Photometrix software suite has been continuously enhanced and through iWitnessPRO and iWitnessPRO-Agilis now offers both fully automatic 3D measurement from multi-image networks, with and without targets, and automatic 3D object reconstruction with texturing to pixel-level resolution. Throughout its ongoing development iWitness has retained its distinction features of maximum ease of use and full photogrammetric rigour to ensure measurement results of optimal accuracy and reliability. Prospective users are encouraged to trial iWitness, iWitnessPRO and iWitnessPRO-Agilis to experience the measurement power and flexibility.
