3d digitizer prototype with calibration

3d scanner concept: - line laser with drive - usb webcam - calibration object - control software scanning procedure: - calibrate system - scan field of view - reposition object - repeat scanning - import into re-software - align different scans system features: - on-site calibration - independent laser positioning - portable - usb connectivity - cheap, simple device system limitations: - reflective surfaces - translucent surfaces - dark surfaces - very intricate surfaces - field of view small - not very fast - requires pricey re-software

3d scanner implementation: - red 2.5mw line laser - geared stepper motor - logitech usb webcam - own design controller - simple control software
