Principes de fonctionnement :
Targets or adapters are placed at all object features relevant to the inspection. There are adapters for boreholes, edges etc. as well as special adapters for measuring reference points. In addition, trim lines, punch holes etc. can be measured without any additional targeting. Then, the targeted part is photographed with a high resolution digital camera from different directions.
These photographic images are processed either simultaneously with data collection (online processing) or after data collection (offline processing) with AICON's powerful software. The software automatically calculates the 3D coordinates of all targeted points. The calculation is based on the principle of spatial image triangulation (photogrammetry) and is fully automated. Pre-calibration of the camera is not necessary because the software employs an integrated simultaneous calibration procedure.
In addition to 3D coordinates, DPA provides statistical analysis of the results with specific accuracy information about each coordinate. This allows for instant evaluation of the quality of the measurement.
Témoignage client :
"3D measurement on the spot"
The young and dynamic company Yachtglass is based in Dersum, just a few kilometers from the Dutch border. Yachtglass offers customers a world wide digital 3D measurement service, measuring the most complicated shapes and forms. For this, the company applies AICON´s DPA system, a portable CMM that uses a digital camera for data collection. Digital measurements, mounting and sealing will be carried out on location according to a scheduled appointment.
"Thanks to AICON's DPA system we can guarantee the highest accuracy level possible, assuring the customer's glass will fit like a glove. Furthermore, we are able to reproduce every single glass ever made."
