描述

算子 calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerasCalibrateCamerascalibrate_cameras 计算由 CalibDataIDCalibDataIDCalibDataIDCalibDataIDcalibDataIDcalib_data_id 指定的标定数据模型的内部和外部相机参数。该标定数据模型描述了一个或多个相机的设置，并在创建数据模型时进行指定。有关标定过程的详细信息，请参考 标定 章节。

优化操作的反向投影结果以均方根误差（RMSE）形式返回至 ErrorErrorErrorErrorerrorerror 参数（单位为像素）。该误差值可大致反映优化操作是否成功。有关 RMSE 的详细说明，请参阅上述章参考资料。

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。

此算子修改后续输入参数的状态：

• CalibDataIDCalibDataIDCalibDataIDCalibDataIDcalibDataIDcalib_data_id

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。
