The PPA is the most common choice when it is given. You may choose whether to enter the PPA or PPS in the Summit camera’s Principal Point fields. If neither the PPA nor the PPS is (0,0), then the fiducial coordinates are not already shifted.Summit Camera Principal Point for PPA=(0,0) Having (0,0) for the PPA or PPS doesn’t mean there is no offset between the FC and the PPA it simply means that the offset from the FC has already been applied to the fiducial coordinates.Ĭamera Calibration Report with the PPA as origin It is common to see the PPA=(0,0), but some old reports may list the PPS=(0,0), especially if there is no PPA on the report. If either the PPS or PPA is (0,0) on the report, then the fiducial coordinates are already shifted to that point as origin, and you should enter (0,0) in the Summit camera’s Principal Point fields.
In this case, the PPS and PPA will not be (0,0), but will have some shift in x, y, or both. If the fiducials are listed with the FC as origin, then they need to be shifted to the PPA (or PPS, it’s your choice). If the fiducial coordinates are already shifted to a better origin than the FC, you have to be careful not to shift them again by entering the wrong principal point in the camera file. When either the PPS or PPA displays as (0,0), it means the fiducial coordinates in the calibration report are already shifted to that point. It is important to enter the principal point correctly in the Summit camera dialog before any measurement begins, because it affects the interior orientation. You must read the camera calibration report carefully to see whether the FC, PPA, or PPS is identified as the origin for the fiducial coordinates. The answer is not always the same, because camera calibration reports from different calibration organizations and from different decades are not always the same. Which one do you enter in Summit’s single Principal Point field in the Summit camera? The camera calibration report lists a fiducial center (FC), Principal Point of Symmetry (PPS), and Principal Point of Autocollimation (PPA). You’re making a Summit camera file for an aerial film camera.

Have Windows 10 already? Here are some more handy tips on the web:
Yes, you can use Windows 10 with a new enough video card. *New!* you have Inpho 1, 7.1.1, or 7.1.2 exporting to Summit 7.2 or higher and the project is in U.S.you don’t know which version of Inpho Match-AT or UAS Master was used.
