ALTITUDE CORRECTION OF TWO SETS OF PICTURES

Hi. 

I have used a dji ohantom 3 pro to capture to sets of pictures. The first set was on a vertical track taken with capture app and the second one I had to restart the drone and did it on free flight. I can see know that I have a sort of mirror effect as if one set of data recorded a different altitude than the other. 

Can anyone point me on the right direction to correct this. I haven’t added and GCP yet. It’s only finished first initial processing. 

Thanks.

Hi John,

Any update on your project?

GCPs should easily solve the issue. It happens sometimes that the altitude coordinate is not accurate when it is recorded above the mean sea level. This probably explains the shift between your mission.

Were you able to mark the GCPs and to reoptimize step 1 so that the two blocks are correctly adjusted?
