How to Use the Maker Bubble Facilities and Services: Structure Sensor 3D Scanner

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.
