[OpenDroneMap-users] ODM_Orthophoto and Georeferencing

Tue Feb 17 02:22:10 PST 2015

Hi to all,

Probably I will be a first to post question to this list. ;) OpenDroneMap
is an great portion of code.
Right now I'm learing how to use it most productive.

But...

I have problem with georeferencing of orthophoto. It seems, that on mesh
model there are correct coordinates (for example, in CloudCompare distance
measuring puts correct distances for
/reconstruction-with-image-size-1200-results/odm_texturing/odm_textured_model_geo.obj).
But generated orthophoto has incorrect coords. Logs in attachment.

With regards,
