write_calib_data — 将标定数据模型存储到文件中。
write_calib_data( : : CalibDataID, FileName : )
算子 write_calib_data stores a calibration data model
CalibDataID into a file specified by its file name
FileName. 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_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_data。
此算子修改后续输入参数的状态：
在执行此算子时，若该参数值需在多个线程间使用，则必须对其访问进行同步。
CalibDataID (输入控制，状态被修改) calib_data → (handle)
Handle of a calibration data model.
FileName (输入控制) filename.write → (string)
The file name of the model to be saved.
File extension:
.ccd
