I am sure many of you have had the same issue but I am wondering what strategies you take to minimise this issue.
To illustrate. I have a flight with 312 images (taken with a sony a5100 from a skywalker 1900 and pixhawk fc). When using georef I get the mismatch with the log file recognising 307 images. Now there are spurious images which were taken using 'trigger now' to test before flight, but when I remove these I still have 308 images. I removed the first image and went through the processing (and then on to Photoscan Pro) and the positional accuracy is poor. I suspect the 'off by one' quick fix did not work! I could do the same again by removing the last image but it looks relevant so I am reluctant to remove it. How do I determine which image is missing? I am assuming the camera failed to fire on one occasion - albeit that seems unlikely.
Any suggestions for an efficient way forward would be very welcome.
