INTRO BACKGROUND DESCRIPTION DESIGN CONCLUSION
What is GigaPan? www.gigapan.org
• Part of Global Connection Project
• Uses a robotic pan tilt unit, standard digital camera, stitching software
• Accessible and affordable method for producing gigapixel images
INTRO BACKGROUND DESCRIPTION DESIGN CONCLUSION
What is Stereoscopy?• Capturing three-
dimensional information• Accomplished using a pair
of images, a left and a right• Can be used to reconstruct
3d scenes, such as anaglyphs
INTRO BACKGROUND DESCRIPTION DESIGN CONCLUSION
Proposed Project• Modify GigaPan setup to accept two
cameras for stereo visioning• Use GigaPan stitching technology to
create gigapixel images that can be transformed into point clouds and anaglyphs
• Optimize for use in site surveys by allowing use of remote control and wireless synchronization
INTRO BACKGROUND DESCRIPTION DESIGN CONCLUSION
Requirements and Ideas• Add a second camera to GigaPan unit• Build anaglyphs using full size Panoramas• Build true 3D models using Vision Workbench• Support External Flash• Bracketed Exposures• Incorporate multiple viewpoints for more complete 3D models• Manually and automatically generated tie points• Incorporate into Microsoft PhotoSynth• Wireless synchronization of multiple Pan/Tilt units• Remote Control of Pan/Tilt units via Serial Interface• External Power Management of Cameras• Create more user friendly software for duplicating procedure
INTRO BACKGROUND DESCRIPTION DESIGN CONCLUSION
The Gameplan• Modify the commercial GigaPan unit to accept a
stereo pair of cameras• Modify camera firmware to be compatible with the
GigaPan unit’s digital trigger• Build software for generating point clouds and 3D
models• Develop more reliable power supply• Test various camera panning strategies to
maximize depth accuracy• Develop a replicable process
INTRO BACKGROUND DESCRIPTION DESIGN CONCLUSION
Architecture INTRO BACKGROUND DESCRIPTION DESIGN CONCLUSION
Potential Issues to Resolve
• Accurate depth representation
• Acquiring second GigaPan for alternate panning strategy
• Cleaning up point cloud artifacts
