Photogrammetry testing in Santorini with BR2


(Othonas) #1

One of our first attempts on using BR2 for photogrammetry. Here we are in Santorini trying to scan a small sandy beach


(Rusty) #2

@Othonas - Very nice! What software did you use to process the imagery?


(Oystein Skarholm) #3

Very Nice. Same as Rusty, I am curious of the software too. Do you have any control of where the photo is taken. Like geomarking?


(Othonas) #4

Thanks Rusty and Oystein! We use Agisoft PhotoScan for generating the model. This was our first try and we didn’t use any geomarking. However we are working on a new project near Athens where we will use control points. The problem that we are trying to work around for now (as I mention in another post) is how we will get the gps position underwater.

I use https://www.pix4d.com/

What is nice about it is you can license it for a month only and compile all your 3d projects.

You will need a super computer though because it takes days to compile.

I cannot share results here because of NDA clauses…

That said results are comparable to the above.

I am working on a similar projects.

I have a method for time tagging the images and then preprocessing the images to insert a georef in the exif header.

Can share if you are interested

There is a really good c++ library for exif in github:
