• Item type calibration

• Source item types:

  required	optional
  input_cameras scene_reference_frame	constraints projected_input_cameras input_control_points projected_control_points

• Resource formats:

  required	optional
  application/opf-calibrated-cameras+json	application/opf-calibrated-control-points+json application/opf-gps-bias+json model/gltf+json application/gltf-buffer+bin
