Deviation Analysis & Inspection
Deviation Analysis is a method of inspection that compares 3D scan data to existing CAD or other scan data. The process is also called Computer-Aided Verification (CAV) or Computer-Aided Inspection (CAI) The output of the process is often called a color map for its bright, colorful visualizations.
Deviation Analysis is an extremely cost-effective way to capture near full-coverage of any part and compare it to a known standard.
1Scanning
Everything begins with 3D scanning. A variety of scanning technologies can be utilized as needed given physical constraints of your part’s material, size and complexity.
2Processing
The resulting point cloud data is then processed to remove noise and ensure a clean scan.
3Alignment
The clean scan data is aligned to the reference data and packaged as an interactive 3D report. The reference data can be an existing CAD model or an STL created from another scanned part.
4Processing
On project close, we will deliver both the 3D interactive report (with viewer software provided) and a 2D report (pdf) as determined by your project requirements.
Flexible Delivery. Powerful Reports
The output of every Deviation Analysis project includes a interactive 3D report, and a powerful viewer app called IMView. The deviation between the base and scan data can be represented in any way that is useful to you - Pass/Fail, color scales with custom range, etc. This viewer/report deliverable provides the ability for you to further interrogate the data and create custom reports in the future. Specific dimensional call outs can be taken from this report and published as a FAI data spreadsheet. This hybrid deliverable is called a CAV Plus.
