underwater lens calibration
« on: November 15, 2015, 10:30:06 PM »
Am looking into way to calibrate camera lens for underwater photogrammetry using Agisoft Photoscan. Am planning on calibrating using Agisoft Lens and a printed calibration grid. Am wanting to calibrate at multiple depths where different temperature and depths can be recorded.

Should I expect much difference between parameters using these variables or would it be better to calibrate lens for a single underwater calibration? Also would multiple images need to be captured or could a single image be used for each re-calculation at depth? Was planning on using multiple images for calculation for initial camera calibration and using single image for each additional re-calculation with depth and temp change.
