Flat surfaces coming out as semicircles or spheres
« on: August 03, 2018, 06:33:18 PM »
Hi folks, I'm using Standard Edition to process calibrated and cropped frames from GoPro footage of coral reefs.
For really rough surfaces, alignment and mesh building are working fantastically. Like so: https://i.imgur.com/1DgBMnw.png
But for flatter, more uniform surfaces, everything curves into semicircles or spheres. Like so: https://i.imgur.com/Ahz83QR.png

It's finding enough overlap to build the terrain properly, but it refuses to make it flat.
How do I correct this? Is there any way to force the camera positions onto a plane?
It is not possible for me to take new videos or images, I can only work with what I already have.
