A quick guide to the Calibration of any camera using ContextCapture
Remove optical stabilization.
Disable photo auto-rotation
If you are unfamiliar with the camera use <<Automatic>> mode
Fix the focal length
Fix image dimensions
Changing the camera focal length (zoom+/-) and / or the image dimensions will result in a different calibration.
Select a highly textured and geometrically complex scene
Acquire photos at 360 deg around the scene
Shoot photos holding the camera in different positions (horizontal / vertical). NB. this only applies if auto-rotation mode is disabled
In the Photogroup tab, select the type of camera being used: perspective / fish-eye
Submit and aerotriangulation. In the aerotriangulation definition settings set << optical properties estimation mode >> to << multipass >>
Go to the Photo tab and right click on the photogroup. Click << add camera to database >>
When processing another project using the same camera, the latest calibration will be used by default. If not you can still browse to it from the camera database by selecting << get camera model from the database >>
In specific cases, you may want to prevent the software from adjusting the camera parameters, i.e. If a calibration already exists or has already been imported from the database.
In the aerotriangulation definition settings, set the focal length, principal point and radial distortion to << keep >>.
