How to Do 3D Scanning: Structure Sensor 3D Scanner

This is a guide for patrons who want to use 3D scanning service at the Learniing Garden of the University Library.

Scanner Information

The Structure Sensor 3D Scanner can be checked out at the Learning Garden Help Desk.

This Scanner uses a process known as structured light, in which an infrared laser projector casts a specific pixel pattern on the scene in front of the sensor. The infrared sensor and camera record distortions in dot pattern at VGA (640 x 480) resolution and creates a 3D-depth map of the scene when you move the Scanner around the scanned object. The scanner has a great potential for 3D mapping and gaming.
