I was recently collecting some test data with a Zenmuse P1 and the resulting orthomosaics were completely scrambled. I'm curious if anyone can provide insight into what might have happened so I can avoid running into this problem on an actual job.
I've attached a screenshot of the satellite base layer for reference, and the resulting orthomosaic after processing. The individual images themselves appeared to be fine. The following setup/settings were used:
- Equipment: M300 + P1
- Mission type: Mapping
- Altitude: 35m
- Side Overlap: 70%
- Front Overlap: 80%
- Image Format: RAW + JPG
- Time Interval shots
- Software: ESRI Drone2Map (reskinned Pix4D)
I flew a total of 4 missions, 3 of the 4 successfully processed but resulted in a scrambled ortho, and 1 failed due to "innaccurate geographic data" or something along those lines. I noticed during flight, the shutter sound from the remote seemed to be triggering at inconsistant times. You'll notice this was actually the case in the screenshots as the spacing between the blue dots is fairly inconsistent.
This is the first time I had tried RAW+JPG mode and one hunch I had was that there was just too much data being saved at once for the SD card or hardware to keep up, although the SD card is reasonably high quality (Lexar Professional 1667x).
Any thoughts on what might have happened and how it could be avoided in the future?
