Ortho Mosaic Visual Defects

Hi All, 

Any ideas about the following? 

Always had very good results with Pix4D but recently been getting this within my ortho-mosaic? 

Any ideas as to why i am getting artefacts over a perfectly good rail? 

You can see there is a clear rail underneath however i am getting this noise over the top? 

Think its an altitude problem in Z axis? 

 

Cheers

 

Hi Dominic,

Is there any noise above the rails that you would see in the 3D point cloud, i.e. points that could from objects close to the rails? If you prefer, you can follow up in the support request that you created.
