Orthophoto from textured Model

[Santa Claus]

Hello

I am looking for a Way to create a Photo/Ortophoto that looks just the same Way as the textured Model, while the Orthomosaic looks very disappointing because the orthorectified images are blended hard together.
 Any Ideas how to solve the Problem?

Hi Santa Claus,

I am not sure if I understand you correctly, but have you tried to export the orthomosaic using PLANAR as projection instead of GEOGRAPHIC (which is default).

This allows you to export a high resolution orthomosaic/photo that can be oriented the same way as shown in your screenshot. You might also want to ENABLE COLOR CORRECTION which could possibly mitigate some of your 'hard blending' issues. You might have already chosen ENABLE COLOR CORRECTION when generating the mesh texture, which would explain why the mesh looks better than your orthophotograph.

Note that you can also improve parts of your orthophotograph (e.g., where you have some reconstruction artefacts) by digitsing a polygon and then assigning a different image to it. Simply open the orthophotograph, digitise the polygon, then right click on the polygon line and choose ASSIGN IMAGES.

Hi Santa Claus !

As SAV tried to said I guess, you can indeed BUILD (before export it ) the orthomosaic using a planar projection. You'll be able to define the projection plane based on markers or on the defined view.

Then define the Mesh as reference surface as it's actually the mesh which is textured in "Textured model". So that you will get the same referenced surface.

As well, as SAV explained, enable color correction may help the mosaic to be more homogeneous. But it will increase the processing time quite well. I would suggest you to try it without this color correction because it's already done a bit without the option. Then try to manually select some part and assign images. If you are really not able to get a good color homogeneity, then re-built the mosaic using hard color correction.

Regards

P.S If you don't get any successful result, may you share the produced orthomosaic so that we may highlight another problem ?

Hi Yoann and SAV

Thanks for your helpful advice. The projection plane was already set to "Planar", but checking "Colour Correction" creating the orthomosaic gives back a much better result. The colours look a bit wild, but the hard edges are gone.
Taking into account that the  lighting conditions in the church were really hard, Photoscan Pro did a very good job.

Hi Santa Claus,

Good to hear that you got some improvement. As mentioned by Yoann, COLOUR CORRECTION increases processing time quite significantly. But it is worth the wait if the results are better
