TerraPhoto camera calibration parameters
The TerraPhoto camera model specifies the following dimensions and parameters of the camera:
•Resolution of images - this is defined by Image width and Image height.
•Orientation - general viewing direction and mounting orientation of the camera.
•Timing offsets - timing corrections to add to the camera event times when computing an image list. They are defined by Timing offset and Exposure.
•Lever arm - an offset vector to add to trajectory positions when computing an image list. The offset vector points from trajectory positions to the focal point of the camera and is defined by Lever X, Lever Y, and Lever Z.
•Camera misalignment - orientation difference between IMU and camera. Defined by Heading, Roll, and Pitch misalignment angles.
•Principal point position - position of the focal point relative to the image center. This is defined by X, Y, and Z image coordinates.
•Lens distortion - a function that models the difference between the lens and a perfectly spherical shape. There are different models available whose constant parameters depend on the type of the function.
