Supported models

Camera models

Kalibr supports the following projection models:

• pinhole camera model (pinhole)
  (intrinsics vector: [fu fv pu pv])
• omnidirectional camera model (omni)
  (intrinsics vector: [xi fu fv pu pv])

The intrinsics vector contains all parameters for the model:

• fu, fv: focal-length
• pu, pv: principal point
• xi: mirror parameter (only omni)

Distortion models

Kalibr supports the following distortion models:

• radial-tangential
  (distortion_coeffs: [k1 k2 r1 r2])
• equidistant
  (distortion_coeffs: [k1 k2 k3 k4])
