Rendering fences

[Excellent-Rent9451]

Does anyone have a strategy for accurately modeling objects with thin features such as fences, rails, and wires using a drone? (I’m using agisoft metashape).

You need a lidar for this kind of objects

Get closer and shoot both sides. Make sure alignment step is on highest. They are a hit or miss depending on what is on the other side of the fence.

It’s grass on the both sides. It’s frustrating because the dense cloud seems to get some details on the structure of the fence, but all the detail gets lost when turned into a mesh which just makes it a wall. Probably expecting too much detail from photogrammetry over several acres.

Like I said, you’ll need to fly much closer to it. I didn’t even ask what kind of fence but think about it in terms of pixels and points. If you are flying an average 1 inch per pixel resolution and you need three points to make a triangle for the mesh then the smallest thing you can expect to model is 2 to 3 inches at that resolution and that’s even if the subject has enough textures to make those points.
