I am using M210 v2 RTK with X7 camera (24mm lens), with DJI Pilot to collect mapping data.Data is post processed with rinex base data and CGP's / checkpoints are used to verify accuracy.
M210 is runnning latest firmware and DJI Pilot is latets recommended version v2.3.1.5.
Pix4D is showing a large error on both checkpioints and geo-location variance.
If I fly the same mission with P4 RTK (SDK controller / DJI Pilot) using same rinex base data and same GCPs / check points, results are very accurate, indicating the issue lies with the M210.
M210 v2 RTK
mean RMS error = 0.034 m
1.38% relative difference between initial and optimized internal camera parameters
P4RTK
mean RMS error = 0.002 m
0.13% relative difference between initial and optimized internal camera parameters
As you can see, the results are not good for the M210.
I would expect slightly better accuracy from the M210 due to the larger sensor of the X7.
Any ideas?
Is it related to the X7 on port 1 being offset from center?
Thanks
Jason
