A test run of this script shows that it does exactly what’s on the label, it writes the lat/long/height to the EXIF data of each image.
This is OK for standard workflows, but it could potentially be a very important part of the complete data that we could generate from the unit. For a directly georeferenced dataset that was captured at 40% side lap, we do not have enough overlap for aerial triangulation and should have a separate file with each image orientation (exterior orientation). This is what is normally collected from larger systems from Leica, etc.
Thus we can then process orthomosaics fairly easily since we have:
- a pre-generated pointcloud
- a pre-calibrated camera
- a file of exterior orientations
While aerial triangulation is possible at the 60% sidelap point, we are then going to be recreating a pointcloud that has already been done (via the laser) and are open to inaccuracies from the bundle adjustment. Not to mention that we will be both wasting time in the field by flying such a dense grid and in the office by processing the same dataset in a variety of ways.
Lets hope this is fairly easy to implement since the coordinates of each event marker seem to be interpolated from the script and that it now needs to be extended to the OPK information. Obviously this can not be written to the EXIF tags since none exist for that information and that a separate ASCII file would have to be generated.
