iWitnessPRO photogrammetry software systemiWitnessPRO is the most affordable automatic close-range photogrammetric measurement system available. Through the use of coded target technology suited to color digital cameras, iWitnessPRO allows the user to achieve accurate, fully automatic measurement of targeted feature points while retaining all the measurement flexibility contained within the manual and operator assisted measurement functions of iWitness.

This leads to rapid, accurate and reliable 3D measurement results and it provides the operator with the freedom to extract further features of interest without the need to manually perform the network relative orientation.


As with iWitness, iWitnessPRO can be used with any digital camera, though the automated functions and measurement accuracy are optimized when digital SLR cameras are employed. Supplied with iWitnessPRO are the necessary re-usable red retroreflective coded targets. Coded targets can be distributed throughout the measurement volume whereas and feature point targets, passive targets, and strip tape targets are optionally used to mark specific points of interest, which do not need referencing by the operator.


The accuracy typically produced with iWitnessPRO, red retrotargets and an SLR digital camera is 1:30,000 of the size of the object. For example, when measuring the shape of an average-sized car, an accuracy in the range of around .01” (.25mm) RMS can be anticipated from a network of 20 images or so.

What our customers say:


“iWitnessPRO has improved our 3D modeling capabilities. The system is easy to use and achieves high-accuracy measurements equal to portable CMMs and other metrology systems we've use in the past for our applications."

“I just mapped the exterior of a wrecked car with iWitnessPRO and it is much more efficient than a Total Station. I successfully mapped the damage using the iWitnessPRO automated codes and targets with excellent results. To map the vehicle with the Total Station (even in reflectorless mode) would have required many setups with the instrument and even then, it would’ve been much more difficult to get all of the damage due to line of sight issues. iWitnessPRO proved to be much faster, easier, and fully automatic with accuracy to thousandths of an inch”.

iWitnessPRO - functionality that makes the photogrammetry difference:

Automatic Processing of RGB (color) Images: iWitnessPRO frees the user from the operational constraints associated with the use of monochromatic (B&W) coded targets and thus greatly enhances measurement flexibility. Color retroreflective targeting is a technology first incorporated in iWitnessPRO, yet such powerful automated measurement capability is now available for $2395.00.


Coded targets 1 to 48: iWitnessPRO comes complete with forty eight coded targets. Additional coded targets (up to 165) can be purchased at an additional fee.


Spinner Codes: These 360 degree rotatable coded targets are used to enhance the measurement of objects ranging from whole cars to the complete surrounds of a crime scene. They enhance network orientation reliability because they can be rotated to be seen in a greater number of images.


Linking: Linking functions in conjunction with the iWitness 3D Transformation to Control, which offers the ability both to automatically link multiple projects together in the 3D Graphics View and to export the measurement results as one cohesive whole in CAD-compatible DXF format.


Additional Utility Programs included with iWitnessPRO

Zaraf: The photogrammetric interior orientation function necessary when measuring from scanned photographic prints or slides is performed by Zaraf. Unlike traditional approaches, Zaraf achieves the interior orientation by directly generating transformed, resampled digital images which simulate those recorded by a chosen camera. This greatly simplifies subsequent photogrammetric orientation in both iWitness and iWitnessPRO. See the Zaraf movie for an example of the process steps.


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. An example project can be seen here, working in cooperation with the Atlanta Police Department. To see how XYRectify was used on a real-world crash imaged by police, review our XYRectify Tip Sheet.
