Supported distortion model

We support 2 image distortion models

  1. brown_conrady &
  2. fisheye

  • A key camera_model in sensor_data.sensor_meta should be there which can expect two values brown_conrady & fisheye

  • If this key doesn't exist or is null, we assume brown_conrady

We will also expect a key called intrinsics.skew. If it is available it will be used in fisheye model.

      ]

In intrinsics, Brown-conrady expects one of these exact combinations:

  1. k1, k2, p1, p2 or
  2. k1, k2, p1, p2, k3 or
  3. k1, k2, p1, p2, k3, k4, k5, k6

In intrinsics, Fisheye expects one of these exact combinations:

  1. k1, k2, k3, k4 or
  2. k1, k2, k3, k4, skew
