2.5 Stitching with FOVEX PanoMaker (continued)
With the report file the user can check the following:
• Time for stitching
• Quality of stitching (RMS – root mean square of residuals- in pixels)
• Possible reasons for unsuccessful stitching
A typical RMS value lies between 0.2 and 0.5 pixels, indicating good quality stitching
(sub-pixel accuracy).
The main reason for unsuccessful stitching can be traced back to in insufficient
features, for examples in regions without texture such as blue skies or blank walls.
