• i need to know these parameters for the RGB camera L1:

  • pixel size in the Y direction
  • Focal length
  • Principal point x0

Can somebody help, please?

Hi, there. Sorry for the late reply.
Please check the below photos for more details.
You need to use DJI Terra to perform the Aerotriangulation, please export the xml file. After the operation is completed, an undistorted photo and an Aerotriangulation report will be generated. Then you can check the Aerotriangulation report to get the parameters you need.

Hello Natalia,

Thank you for your reply, please do you know how to know every parameter unit, And how to convert from Pixel to millimeter.

The focal length listed in the tags for the L1 RGB images is 8.8mm. I know you are trying to do photogrammetry using these values as inputs but there are other ways to figure out the GSD (cm/pixel).
