Processing the LiDAR calibration.

Started with the navigation data but had some problems getting an adequate solution. Emailed Leica support to see if they can help.

comment:3 Changed 12 years ago by emca

Ops are going to attempt to fly another calibration over Little Riss on Saturday (12/05/2012) so if that is sucessful then won't proceed any further with this data.

comment:4 Changed 12 years ago by emca

Leica got back about the nav data and have been able to get an improved solution - contuinuing with the LiDAR calibration.

comment:5 Changed 12 years ago by knpa

Proceeding with HS calibration.

Found SCTs for lines to be used in boresight:

1 -0.03 -0.03
2 1.86 -0.06
3 0.01 -0.06
5 0.00 -0.03
6 0.00 -0.06
7 -0.02 1.82

Lines E2 and H2 have no sync messages.

H: -0.33 0.28 0

Processed the LiDAR calibration

Couple of points to note:

  • the roll error is still evident in this data - emailed Leica support but not heard back from them yet
  • due to lack of ground control points at nadir the range correction needs to be verified against another dataset (a cal flight over little riss)
  • data that is processed using this calibration should be checked carefully for any boresight errors

Processed the day 082 data and found a slight height offset (~15cm) from the GCPs - redid the range correction using the little riss data

Camera delivery had been finalised. Had a quick look at all OK so marking as finished on the status page.
