This document outlines an evaluation framework for 3DoF+ virtual reality systems. It discusses different configurations for the input (single/multiple 360° cameras or 180° cameras) and evaluation methods based on those inputs. Evaluation involves comparing a rendered virtual view from the input views to one or more reference views to assess virtual view quality. Reference views can be partial 180° views or full 360° views, and evaluation is done by comparing at the location of the reference views.

- 1. Overview of the evaluation framework for 3DoF+ Krzysztof Wegner Chair of Multimedia Telecommunications and Microelectronics Poznań University of Technology, Poland
- 2. 2 Output – single 360 view 360o Output of the system is 360 view which can be displayed directly on HDM
- 3. 3 Input – single 360 camera 360o Input to the system can be single 360 view with any projection
- 4. 4 Input – multiple 360 cameras 360o 360o 360o Input to the system can be multiple 360 view captured from different location is space
- 5. 5 Input – single 180 camera 180o Input to the system can be (???) single view less than 360 degree, captured from single location, not covering entire sphere
- 6. 6 Input – multiple 180 cameras 180o 180o 180o Input to the system can be (???) multiple view less than 360 degree, captured from multiple location not covering entire sphere
- 7. 7 Input – multiple 180 cameras 180o 180o 180o 180o Input to the system can be multiple view less than 360 degree, captured from multiple location covering entire sphere
- 8. 8 Evaluation – single 360 camera 360o 1 – input 360 view 4 – reference 360 views for virtual view quality evaluation 1 – virtual 360 view – rendered from input view 360o 360o 360o 360o 360o Compare virtual view rendered from input 360 view at location of reference 360 view
- 9. 9 Evaluation – multiple 360 camera 360o 3 – input 360 views 4 – reference 360 views for virtual view quality evaluation 1 – virtual 360 view – rendered from input view 360o 360o 360o 360o 360o Compare virtual view rendered from input 360 view at location of reference 360 view 360o 360o
- 10. 10 Evaluation – single 180 cameras 180o 180o 180o 360o Compare virtual view rendered from input 180 view at location of reference 180 view 1 – input 180 view 2 – reference 180 views for virtual view quality evaluation 1 – virtual 360 view – rendered from input view
- 11. 11 Evaluation – multiple 180 cameras 180o 180o 180o 360o Compare virtual view rendered from input 180 view at location of reference 180 view 3 – input 180 views 2 – reference 180 views for virtual view quality evaluation 1 – virtual 360 view – rendered from input view 180o 180o
- 12. 12 Evaluation – multiple 180 cameras 180o 180o 180o 180o 360o 8 – input 180 views ? – reference ?? 1 – virtual 360 view – rendered from input view
- 13. 13 Partial reference views 180o 180o 180o 180o 360o 4 – input 180 views 4 – reference 180 views 1 – virtual 360 view – rendered from input view Partial comparison at reference 180 view location
- 14. 14 Full 360 reference views 180o 180o 180o 180o 360o 8 – input 180 views 2 – reference 360 views 1 – virtual 360 view – rendered from input view 360o 360o Full comparison at reference 360 view location
- 15. Conclusions We always need 360 reference view for quality evaluation Quality evaluation should be done at the location for reference view
