Point cloud inspection

Leading soft­ware for 3D point cloud inspection

Metrolog 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 algo­rithms for han­dling scanned point cloud data result in improved qual­ity and pro­duc­tiv­ity within your man­u­fac­tur­ing process.

Although the qual­ity of 3D scan­ners has 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 into point cloud inspection.

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.

Point cloud inspection 4

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.
