We are working on a high-accuracy geotagging solution that should ultimately be capable of providing the location of the GPS antenna within 2-3cm.
As I am sure most of us are aware, the GPS antenna is not usually where the camera is located on an aircraft/drone and there will be an offset. This offset will be fixed (relative to the camera coordinate system), so long as the camera is not mounted on a gimbal.
Since our high-accuracy geotagging solution won’t have an IMU on it, we cannot pre-account for the antenna offset before importing the camera positions into Pix4d.
Here are my questions…
Will Pix4D automatically figure out that there is a constant offset, account for it, and still output a mosaic that has a georeferencing accuracy close to the 2-3cm range?
If the software can’t automatically determine/account for the constant offset, would it be possible for a user to simply type in the offsets (X offset: 5cm, Y offset: 10cm, Z offset: 20cm, for example) relative the camera coordinate systems since Pix4d effectively determines the orientation of each camera during its initial processing anyway?
