Feature Requests / Cross-section based dense cloud editing / classification
« on: February 05, 2017, 01:13:30 PM »
While being an amazing Software for photogrammetry, the biggest challenge in PhotoScan is cleaning up a dense cloud and classify it to get a proper DTM.
While the automatic classification algorithm is doing a good job, there is always some (often a lot) manual work to do.
I had the chance to work with Global Mapper for a while, and one feature that was very helpful was the ability to view a cross-section of a point cloud and the ability to select points from there to be modified and classified. You can see how it works here: https://www.youtube.com/watch?v=v8VM2vkw43g&feature=youtu.be&t=3420
Long story short: you define a cross section path and a range (example +-0.5m) and all the points lying in this slice are viewed in a cross-section window. From there you can select points and edit them.
In the attached screenshot i generated a length-profile with a cross-section every 1m...
