How Does a White Light 3D Scanner Work? [With Video]

Posted By Thomas Tong on March 1, 2012 at 12:00 PM

In the previous blog post, Ways to Automate 3D Scanning, we briefly explained the steps to create a full 3D model from a physical object. The best way to illustrate this process is through a video demonstation. Below is a video of the 3D scanning process using a white light 3D scanner (also known as a structured light 3D scanner). White light 3D scanners are categorized as non-contact 3D scanning where the scanner scans without physical contact with the object to ensure there is no measurement interference.In this video we use the HDI 3D Scanner to demonstrate this process:

For comparison, here is a photo of the actual object:

Here is a rotation of the 3D model once all the 3D scans have been merged.
