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
