texture and orthomosaic from single spherical images
« on: February 28, 2019, 07:57:10 PM »
i have added 3 spherical images, aligned them and added markers to set an arbitrary local coordinate system.

i then imported a planar mesh (densely triangulated, from 3dreshaper) and tried building texture and orthomosaic from just one of the spherical images to get a nice floor orthophoto.

in both cases i get an unfortunate artefact where the spherical image wraps around. In the textured mesh the triangles at the seam are not textured at all, and in the orthomosaic the seam has some crazy distortion going on as shown in attachments.

Hello James,

Can you share the project with the single chunk that contains the alignment results and imported mesh with the texture applied?

Hello James,

Thank you for providing the project file.

It seems that the imported mesh surface is about 0.247 local units higher than the real floor surface. And the dimensions of this imported surface are also smaller than the actual floor dimensions (in local units) by the similar factor.
