Need help to classify points
« on: September 19, 2014, 10:02:21 AM »

First of all, let me appologize, and say thanks in advance for any helpful tip. I am still pretty new to Photoscan.

We have been out with our Drone, and have taken pictures of a small quarry.
Our task is to produce a high quality georeferenced orthophoto, a detailed map with contour lines and do a mass calculation of remaining mass in the quarry.

The Orthophoto is fine, but the contour lines and mass prosjection is what I'm having trouble with.

The reason for this is the trees that are on top of the hill behind the quarry. They are generating too much fuzz, and makes the contour line software super confused.

Its the same with the mass calculation software, it includes the trees, which makes the projection accuracy low.

I have tried to classify points, but the result becomes even worse regarding the trees.

So if anyone have done a similar job, please share some tips, and I will be super gratefull.
