Question

How to use GPS/IMU data in IMAGINE Photogrammetry to rectify aerial images?

Answer

The GPS/IMU provides x-y-z as well as the omega-phi-kappa. If you click the exterior information button when assigning your camera or setting up your fiducials, you will see all of the fields to insert your data. You must import your exterior orientation here to fill in the x-y-z and omega-phi-kappa information. The standard deviations for the rest of the x-y-z and omega-phi-kappa can be set to Fixed if the GPS/IMU data is highly accurate or triangulation is not required.
