Description

The operator write_calib_datawrite_calib_dataWriteCalibDataWriteCalibDatawrite_calib_data stores a calibration data model CalibDataIDCalibDataIDCalibDataIDcalibDataIDcalib_data_id into a file specified by its file name FileNameFileNameFileNamefileNamefile_name. The information stored in the file includes:

  • initial camera parameters

  • calibration object descriptions

  • observation data

  • model settings: generic and specific optimization parameters for both cameras and calibration object poses.

Note that no calibration results are stored in the file. You can access them with the operator get_calib_dataget_calib_dataGetCalibDataGetCalibDataget_calib_data, either as individual items or in form of a camera setup model and store them separately.

The calibration data model can be later read with read_calib_dataread_calib_dataReadCalibDataReadCalibDataread_calib_data.

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.

This operator modifies the state of the following input parameter:

During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.
