DPA Professional
High-end 3D measurement with a handheld digital camera
Would you like to know more?
The high-end handheld digital camera at the heart of the DPA Professional package offers maximum flexibility in spatially confined or hard-to-reach areas. After signalisation with the included extended range of targets, adaptors and scale bars is complete, image capture and measurement result production take mere minutes thanks to the advanced functionality of the DPA Pilot software platform.
Able to measure objects of any size, from small components to whole airplanes, typical applications of DPA Professional include deformation analysis, tolerance analysis, fixture measurement and CAD comparison.
As an expert-level system, DPA Professional puts control of all settings directly in the hands of the user and is therefore well-suited to metrology professionals familiar with the concept and typical implementation of typical photogrammetry processes.

The DPA Series
Handheld photogrammetry
When it comes to shop-floor measurement processes, it’s important to have a simple workflow that’s as immune as possible to user error and the hazards of an industrial environment. That’s why the DPA Series photogrammetry systems have been designed to deliver user-friendly measurement and processing in every situation.
Relying on just a single handheld camera unit backed by a dedicated software platform, DPA Series systems are among the most portable measurement systems in the world, without compromising on metrology-grade accuracy delivered at productivity-enhancing speed.
DPA Series systems are available in three configurations that allow the user to tailor their experience to the needs of their applications. Each system runs on the same advanced DPA Pilot software platform – the foundation of the leading measurement functionality of the DPA Series.

Introduction to photogrammetry
How digital photogrammetric analysis works
The DPA Series systems are portable 3D measuring tools that use a high-resolution digital camera for data collection. They are based on the principles of digital photogrammetric analysis. Measurement with a photogrammetric system involves the following four key steps.
1. Signalising
To measure a part, it is first signalised with a selection of targets. Coverage of hidden points or features such as holes and edges is ensured with the use of appropriate target adaptors.
2. Capturing
The part is then photographed from several directions, with the targets in view and overlapping between shots.
3. Calculating
The images produced are processed either simultaneously with data collection (online processing) or after data collection (offline processing) through a dedicated photogrammetry software tool like DPA Pilot. The software automatically calculates the 3D coordinates of all targeted points.
The calculation is based on the principle of spatial image triangulation and is fully automated. With software that employs an integrated simultaneous calibration procedure, the highest levels of accuracy can be achieved onsite during the measurement process.
4. Reporting
In addition to 3D coordinates, quality photogrammetry software such as DPA Pilot can provide statistical analysis of the results with specific accuracy information about each coordinate. This allows for instant evaluation of the quality of the measurement.
DPA Pilot is also very deeply integrated into the best inspection software packages and allows complete automations of calculation steps and advanced analyses.
