Point cloud inspection - Metrologic Group

Point cloud inspection

Leading software for 3D point cloud inspection

Metrolog X4 is the reference for 3D point cloud inspection. Not only does it speed up the inspection process and gain in throughput inspection time, but it also contributes to increased measurement precision and less scrap. Powerful and robust Metrolog X4 algorithms for handling scanned point cloud data result in improved quality and productivity within your manufacturing process.

Although the quality of 3D scanners has been improved greatly in recent years and they are employed at a growing scale for faster point acquisition for parts or applications where contact measurement systems cannot make it, inevitable measurement errors in point cloud still occur. Our goal is to respond to this critical challenge by bringing more precision to 3D scan systems and help you gain deeper insight  point cloud inspection.

Unlock the full potential of your Point Cloud inspection process with industry’s most robust and accurate 3D scan processing software. 

Why choose Metrolog X4 for your 3D point cloud inspection

  • Unrivalled 3D point cloud acquisition, processing and analyzis toolset allowing you to fix and prevent problems in the earlier stage of the manufacturing process.
  • Fully embedded and seamlessly integrated scanning and quality control for all CMM/ robots and latest optical 3D measurement technology available on the market.
  • Real-time display and computing of your ongoing measurement results to monitor your inspection: all the feature characteristics and results.
  • Advanced capability to collect and perform full analysis of heaviest 3D point cloud data without decimation.
  • True point cloud feature extraction based on Y14 & ISO 1101 GD&T compliance

Complete toolset

The most complete and easy to use toolset for comparing forms and profiles (part-to-part and part-to-CAD), highlighting areas that are out of tolerance. It also includes the most full-scale GD&T analysis capabilities on the market.

Direct projection

Rapid and accurate Point Cloud analysis using direct projection onto the part CAD file. The projection is based on the polynomial model and not the faceted and approximated one.

Feature inspection

Extensive surface and feature inspection set of functions for full control of your surface quality layout. Perform reliable feature extraction and fast colour mapping, directly from your scan data.

CAD cloud fitting

Accurate and easy-to-use alignment functions and best-fit. Multiple solutions available for cloud fitting to CAD: autofit, best-fit, manual fit, or cloud to cloud fitting.

Reporting tools

Manual or program-based dimensional analysis with generation of easy to interpret and interactive reporting enabling rapid decision-making.

Easy programming

No need to be an expert in programming. Quality compliance control of final manufactured and assembled products can be carried out through accessible automated techniques.

Multi-sensor ready

We offer an extensive retrofit kit adaptable to any 3D measuring machines and capable to integrate most of the existing optical sensors available on the market.

Free i-Viewer app

Collaborate and dynamically exchange your point cloud data with your engineering team by using i-Viewer app: easily share your inspection results with customers, partners or subcontractors.

See how our expertise can address your most critical 3D inspection challenges faster than ever.
