Project Description Sole Supports needs an electronic aide in their current orthotics manufacturing process Sole Supports needs an electronic aide in their current orthotics manufacturing process Goal: Goal: –Create a method for 3-Dimensional imaging and potentially supporting software for Sole Supports

The Old Orthotics Manufacturing Process

The Current Orthotics Manufacturing Process

The Future Orthotics Manufacturing Process

Goals Make a 3-D imaging device Make a 3-D imaging device –Resolution: < 5mm –Accuracy: 95% within 2mm –Device Dimensions: < 3ft x 3ft x 3ft –Easy to use Create software program Create software program Overall Cost < $400 Overall Cost < $400

Proposed 3-D Imaging Setup Solutions Cameras in Stereo Pairs Cameras in Stereo Pairs –Algorithm hard to automate Sick® Laser Range Finder Sick® Laser Range Finder –Too expensive Flatbed Scanner Flatbed Scanner –Inaccurate DAVID software with Laser Level and Camera DAVID software with Laser Level and Camera –Meets initial criteria
