DPA Professional
Hoogwaardige 3D-meting met een digitale handcamera
Wil je meer weten?
De hoogwaardige digitale handcamera die centraal staat in het DPA Professional-pakket biedt maximale flexibiliteit in kleine ruimtes of lastig bereikbare gebieden. Na voorbereidingen met behulp van het bijgeleverde, uitgebreide assortiment richtmerken, adapters en schaalbalken, duurt het vastleggen van een opname en het produceren van meetresultaten slechts enkele minuten, dankzij de geavanceerde functionaliteit van het DPA Pilot-softwareplatform.
Omdat het geschikt is om objecten van iedere grootte te meten, van kleine onderdelen tot hele vliegtuigen, kan DPA Professional met name goed gebruikt worden voor vervormingsanalyse, tolerantieanalyse, opspanmetingen en CAD-vergelijking.
DPA Professional is ontwikkeld voor experts en geeft de gebruiker dus alle controle over de instellingen en is daarom goed geschikt voor metrologieprofessionals die bekend zijn met het concept en de implementatie van fotogrammetrieprocessen.

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.
DPA Industrial
- High-end industrial sensor - 50.6 megapixels
- Simplified control schema minimises operating errors during measuring tasks
- Full range of measurement targets, adaptors and scale bars
DPA Professional
- High-end sensor - 30.3 megapixels
- Full control of all camera settings directly in the hands of the end-user
- Extended range of measurement targets, adaptors and scale bars
DPA Entry
- Mid-range sensor unit
- Full control of all camera settings directly in the hands of the end-user
- Basic range of measurement targets and scale bars

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.
