calibrate_camerasT_calibrate_camerasCalibrateCamerasCalibrateCameras (Operator)

Name

calibrate_camerasT_calibrate_camerasCalibrateCamerasCalibrateCameras — Determine all camera parameters by a simultaneous minimization process.

Signature

Description

The operator calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerasCalibrateCameras calculates the internal and external camera parameters of a calibration data model specified in CalibDataIDCalibDataIDCalibDataIDCalibDataIDcalibDataID. The calibration data model describes a setup of one or more cameras and is specified during the creation of the data model. You can find detailed information about the calibration process in the chapter reference Calibration.

The root mean square error (RMSE) of the back projection of the optimization is returned in ErrorErrorErrorErrorerror (in pixels). The error gives a general indication whether the optimization was successful. You can find more details about the RSME in the chapter reference mentioned above.

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:

• CalibDataIDCalibDataIDCalibDataIDCalibDataIDcalibDataID

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