I am processing photos from a Phase One camera with an accurate camera calibration but Im not sure exactly what is happening when I enter the calibration for processing. Is it using the calibration during processing or are the values I enter only used as a comparison to what Context Capture gets?
Also, the camera came with 3 different calibrations - Australis, USGS, and INPHO. I think I use Australis but Im not positive because if I let Context Capture adjust the calibration, the distortion values are not even close to what I entered.
Any help with understanding the camera calibration aspect of Context Capture would be great.
Thanks!
Dear Amicron,
The camera calibration that you import is indeed used as a starting point during the aerotriangulation process. Depending on the settings you are using, the camera calibration will be either adjusted during the bundle adjustment phase, or kept as is.
In the aerotraingulation setting page, you can choose to "adjust" or "keep" the following parameters :
-focal length
- principal point
- radial distortion
-tangantial distortion
-aspect ration
-skew
In contextcapture user manual, there is a section about "contextcapture camera model" if you need more information about the camera model that we are using.
Thanks,
Sylvain
