I’m using Metashape to create a model of a fossil track way cast. I’ve only shot the top of the cast, so in a sense, it’s a 2D object with relief like a wall carving or mural. When generating either a dense point cloud or mesh, I end up with black borders around my outputs. Even after I’ve removed the black border from around the dense point cloud prior to meshing, I still end up with a black border.
I’ve tried masking my photos twice, first using the built-in tools in Metashape, and then using Affinity Photo. I get the same results either way. I’m not sure if this would make a difference anyway.
In the case of the mesh, disabling interpolation does prevent the border, but leaves holes in my mesh. I probably could then fill in the holes, but considering I plan on taking measurements from these models, I’m hesitant to do much post-processing.
I’m certainly far from proficient in the photogrammetry workflow. Is this something that’s unavoidable and I just have to manually remove the border, or is there something else I can do to avoid this all together?
