DPA Professional
Medição de coordenadas em 3D com câmera digital portátil
Você gostaria de saber mais?
A DPA Professional mede objetos de qualquer tamanho, de componentes pequenos a aeronaves inteiras. As aplicações típicas são análise de deformação, análise de tolerância, medição de dispositivos e comparação com dados do CAD.
As medições com a DPA Professional são muito fáceis de realizar em duas etapas. Marcas de referência e adaptadores sinalizam os pontos importantes do objeto. Com a câmera digital, o objeto é fotografado a partir de diferentes ângulos para que todas as áreas importantes sejam capturadas.
A avaliação e o calculo do adaptador das coordenadas 3D determinadas ocorrem de forma totalmente automática. O usuário recebe um relatório de medição otimizado, incluindo a análise estatística dos resultados.
A câmera digital portátil oferece a máxima flexibilidade em áreas com espaços confinados ou de difícil acesso. O DPA Professional não requer uma posição estável do instrumento, o que é uma vantagem enorme para medições em ambientes instáveis. Mesmo que os resultados sejam necessários em tempo mínimo, a DPA é o sistema ideal. Os resultados de medição estão disponíveis em poucos minutos após a conclusão da aquisição da imagem.

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.
