About Global Inspection Solutions

Global Inspection Solutions was founded in Portland Oregon in 2009 by engineers that believed there had to be an better way to get real parts into digital 3D. We researched all of the 3D scanning technologies, and found a fantastic solution with 3D3 Solutions FlexScan scanner. We've built a series of custom scanners around the FlexScan technology, and have been making extraordinary 3D captures ever since. We have also expanded our capacity to help our customers create new 3D CAD data for machining and manufacturing, and digitally inspect complex 3D shapes that would otherwise be impossible with traditional CMM inspection techniques.

Optical Scanning

Many of the mainstream 3D scanners available on the market operate on the basic principle of optical triangulation. To accurately capture three-dimensional surface data requires a high quality camera, and a light source of a known position. Because the distance between the light source and the camera is fixed, the distance to the part surface can be calculated by forming a triangle between the camera, light source, and the surface of the part. A 3D scan measures many points over the entire part surface, often 1-2million for any scan, and generates a surface by connecting all of these points with tiny triangle surfaces. The result is a 3D surface mesh that accurately reproduces the shape of the part, and can be used for animation, reverse engineering, and 3D measurement.

Laser Scanning

In a laser scanner, a laser line is projected across the surface of the part. The camera picks up the laser line and calculates the 3D contour of the line. As the laser moves over the shape of the object, a 3D surface is captured, one line at a time. Lasers can be used to create good quality 3D scans, but the process can be slow and not safe for scanning human faces.

White Light Scanning

A white light scanner projects a sequence of images that can be used to generate a series of very thin, white lines much like a laser. The process is similar to that of a laser scan, but it is possible to capture much more detail in much less time. White light scanning produces very high quality, detailed scans with very little surface noise, and because there is no laser involved, we can safely capture human faces with excellent detail.
