Introduction
How Stereo Vision Works
Methods
Future Work
1• 3-D scanning is the process of converting physical objects to
numerical data that can be geometrically represented.
• Digital models allow for testing and redesign of real objects without wasting physical resources.

Image Capture
Disparity Maps
3-D Representation
• Easy to setup/use software and hardware
• Quickly capture sets of stereoscopic images
• Generate 3D model from disparity map

• Higher resolution for better modeling
• 3-D Printing integration
• Larger scanning area
• Faster processing time
Known• D-wall• D-center
Calculate• D-object• Object size
• 2 images of same object (slightly different angles)
• Find pixels on each image corresponding to same point on real object
• Triangulation to calculate distance from real object to cameras
