Measurement of Surface Roughness
« on: January 26, 2019, 01:18:26 AM »
I have created 3D models of some Frost surfaces using Agisoft photoscan and tried to evaluate the roughness parameters (RMS value and peak-to-valley height).  Camera position was known in sort of coordinates and microscopic photos were taken. However, The error for one surface was much higher while evaluating the RMS height percentage difference and peak-to-valley height. Would you please recommend me how to minimize this error using Agisoft or any other photogrammetry software?  Thanks.
