Does stitching have an influence on roughness measurements?


#1

What happens to my data during the stitching process, especially at the seams? What impact does this have on data analysis?


#2

When there are multiple data points available for a single pixel in the stitching area, the height data of the all available sub-sets will be averaged. This will have an impact on the noise level in those areas, that is to say that more averaged scans increases the signal-to-noise ratio. This means that the roughness measurements will likely yield lower values on stitching seams compared to areas away from the seams.
