Stanford 3D Scan Cart
Goal: Make it easy for a single person to capture a 3D model of an entire building interior.
About
How does it work?
A 3D model of a building interior is captured by pushing the scancart through the building, moving room by room. Periodically a 360 degree depth and photometric measurement is made using a SICK laser range finder and a digital camera mounted on a pan-tilt head. Odometry from the cart wheel encoders is used to initalize a photometric + geometric alignment between adjacent scans (ICP).
Applications
What can it be used for?
- Capturing the as-built environment for real-estate virtual tours
- Design and simulation of distributed camera sensor networks installed in buildings
