Hello.

We have got liner projects. We flighed in one mission line.

But for some flight there is some problem maybe and we can not merge all of them or can not procces all of them together. It can not do image matching normally.

Could it be due to drone data?

I am ready to share example of data from here:

Hi,

Welcome to Pix4D Community!

Several conditions need to be fulfilled to be able to merge projects; please make sure that these requirements are in place:

  • The coordinate system (both horizontal and vertical) of the images has to be the same in all subprojects. Note: A subproject with no image geolocation can be merged with a subproject with image geolocation.
  • The GCPs have to be in the same coordinate system (both horizontal and vertical) in all subprojects. Note: A subproject with no GCPs can be merged with another subproject with GCPs.
    It is highly recommended the GCPs to be added in the merged project, especially when more than 2 subprojects are merged.
  • The output coordinate system (both horizontal and vertical) of all subproject has to be the same. Note: A subproject with no georeference (arbitrary system) can be merged with a subproject with georeference.

Another important aspect is that you must be able to identify and mark a minimum of three manual tie points (MTPs) with the same name and point to the same feature on both projects.

You can get more information about merging projects in the following article: How to merge projects

But for some flight there is some problem

Please could you post the quality report here to check those problems? This will make faster the troubleshooting process.

Have a very nice day!
