Description

The operator read_calib_dataread_calib_dataReadCalibDataReadCalibDataread_calib_data restores a calibration data model from a file specified by its FileNameFileNameFileNamefileNamefile_name and returns a handle to the restored model in CalibDataIDCalibDataIDCalibDataIDcalibDataIDcalib_data_id. The model file must have been created by write_calib_datawrite_calib_dataWriteCalibDataWriteCalibDatawrite_calib_data.

Note that write_calib_datawrite_calib_dataWriteCalibDataWriteCalibDatawrite_calib_data does not store any calibration results into the file. Yet, calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerascalibrate_cameras can be called for a fully configured calibration model immediately after the reading. All calibration results are accessible afterwards.

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 returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

FileNameFileNameFileNamefileNamefile_name (input_control)  filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

The path and file name of the model file.

File extension: .ccd

CalibDataIDCalibDataIDCalibDataIDcalibDataIDcalib_data_id (output_control)  calib_data → HCalibData, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of a calibration data model.
