Wrong texture when exporting orthophotos
« on: March 09, 2017, 11:54:02 AM »
Hello,

We are working in a documentation project for old buildings.

We are making chunks for each space / room. and then we need to export orthophotos for each facade, in some spaces, when we clean the walls and leave only the wall we want to export the orthophoto of, the result takes texture from other wrong surface, although before exporting (in the program itself) the texture preview is just perfectly fine.

Any suggestion as to what is causing this issue.

Attached are examples showing the wrong texture.

Thanks in advance.

In the attachments you can see one example using mosaic and average blending modes. The average blending mode gives better results but still not as good as what we are typically getting.

Hello Ahmad,

Please specify, which version of PhotoScan you are using? Also are you speaking of Orthomosaic or Texture generation?

If possible, please also provide the screenshot of the model with camera positions overview with the highlighted area of interest.
Best regards,

Hi Alexey,

The version is 1.2.6 build 2834 (Professional version)

I am talking about building orthomosaic. Building texture is fine it seems.


After though: After you requested the camera positions,We tried building orthomosaic with the unnecessary cameras disabled, and the result is better, anything else to be done?

Removing the cameras solved the issue, we had the camera positions hidden before so it didn't come to mind to disable/remove them. Thanks!
