Human Factors and Ergonomics Problem:
• Lengthy setup times for motion capture cameras• Trouble avoiding obstacles to camera fields of view• Uncertainty predicting actual usable camera volume
(Where three cameras or more intersect)• Existing system recognizes volume as a cube • Existing systems does not recognize or account for
obstructions
![Page 6: CATIA V5 knowledge-based camera field-of- view modeling ...](https://reader030.fdocuments.in/reader030/viewer/2022020623/61efc08e7b91924490107e45/html5/thumbnails/6.jpg)
Needs
• System placement evaluation prior to arrival on location
• Camera placement that maximizes effective capture volume
• More accurate volume prediction geometry

Proposed Solution (V1)
• Capture volume prediction model based on camera positions
• Capture volume defined as the intersection of three camera fields of view
• Highly mobile and easily positioned cameras

Proposed Solution (V2)
• Added object obstruction to volume predicting model• Quick obstruction setup and activation• Ensured proper obstruction propagation • Created user parameters similar to motion capture
system controls
