Efficient Separation Between Projected Patterns for Multiple Projector 3D People Scanning
2017
2017 IEEE International Conference on Computer Vision Workshops (ICCVW)
Preserved Fulltext
Such a choice enables simple and efficient separation between projected patterns. ...
Using multiple projectors in structured light profilometry is a challenging problem due to inter-projector interferences which make pattern separation difficult. ...
