Ortophoto water

[Peter]

I have a new mission coming up where the client wants to map the parts of the ocean. The area is quite  shallow and maybe if i use polarising filter i might work and agisoft can see ocean bottom in the images and make aligment based on that.

Has anyone tried this?, would it be possible

I know from tha past that water is big problem due to lack of textures

Hi Peter

You can test and I hope that you succeed! If so, please give me your tricks. I do not want to deceive you in advance but, however, I tested something similar, with polarising filters and, even considering that you can eliminate all the reflections, you have the water refraction angle. If you tilt the camera over the photographed area the angle change by the air/water fluids will completely fool agisoft Photoscan or any other photogrammetric software. The only possible way is to do the photos completely submerged. From the air, if the water ripples slightly (I do not even talk about small waves), the refraction will completely destroy your 3D model.
Cheers
