Clipped ortho projection

Hi, I’m an archaeologist, and RealityCapture user for three years - for landscape photogrammetry and 3D modelling.

I have been trying to generate an ortho projection from a model based on a drone survey (400 photos) of a glacial feature.

The model is fine, and I can extract the full .las point cloud. However, despite multiple attempts the ortho projection is randomly clipped much narrower than the surveyed area. I have tried changing the projection from Arbitrary to Top, I have tried with a reduced, and also with a widened, reconstruction area, to no avail. I have used the same process in the past to model another feature nearby without a problem.

Is there anything I could try to solve it, or is it a bug?

Many thanks,

Martin

Hi Martin,
what are your ortho creation settings?
IS this also happening after application reset? Have you tried to set the reconstruction region differently?

Hi othran,

Thanks for your feedback. I have tried multiple times to change the reconstruction area - bigger, smaller, thicker, thinner. Settings were WGS84 pseudo-Mercator for the output. It seems to be working better with OSGB36 (EPSG27700), but in terms of data integration it isn’t the best - particularly with the message “Reference system cannot be saved in the file” or something.

It would be great if there was a fix to make it work in all EPSGs, and especially the most common ones. Any suggestions welcome!

Have you tried also that application reset?
The message is for all coordinate systems unless it is WGS84. These systems is not possible to write into format and it needs to be set in the application where you want to open the ortho.
Were you using mosaicing or true ortho from textured model to create the ortho?
