DPA Inspect - Portable 3D Industrial Measurement Systems

   DPA Inspect systems permit onsite inspection and error detection without time-consuming interruption of production lines. DPA Inspect systems are ultra-portable pieces of equipment that no longer require that parts be transported to a Coordinate Measurement Machince (CMM).  DPA photogrammetry can be used in unstable environments and locations which are difficult to access.

Benefits:

 

Onsite inspection and error detection without time-consuming interruption of production lines.

 

Extremely light-weight and ultra portable.

 

No measurement size restrictions. Measure parts from a few millimeters up to many meters in size.

 

stable measuring instrument positions are not required.

 

Results within seconds of completion of measurements.

 

Designed to integrate with PolyWorks, RapidForm, Metrolog, Metrosoft and other measurement software packages.

Applications

 

Inspection of sheet metal parts and tolerance analysis

 

Fixture inspection

 

Comparison with CAD

 

Roundness inspection, e.g. tunnels or tanks

 

Measurement of large steel fabricated structures

DPA

 

Images can be processed at any time and are independent of the recording device

 

Statistical analysis of results are provided with specific accuracy information of every coordinate.

 

Software automatically calculates the 3D coordinates of all targeted points.

Measuring Principle

 

AICON’s DPA systems are portable 3D measuring machines that use a high resolution digital camera for data collection.

 

The part can be any size and is photographed from a number of directions.

 

Photographic images are processed either simultaneously with data collection (online processing) or after data collection (offline processing)

 

Software automatically calculates the 3D coordinates of all targeted points 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.

AICON's DPAPro and DPAInspect are capable of measuring parts ranging in size from a few millimeters to many meters in size. Objects as large as aircraft can be measured. AICON's DPA systems employ hand-held digital camera suitable for use on large objects that cannot be moved to a CMM. AICON's DPA systems are especially appropriate for use when the environment requires that time onsite be minimized. Results are delivered by AICON's powerful 3D Studio software within seconds of measurements completion.
