Description

The operator set_calib_data_cam_paramset_calib_data_cam_paramSetCalibDataCamParamSetCalibDataCamParamset_calib_data_cam_param sets the initial camera parameters CameraParamCameraParamCameraParamcameraParamcamera_param for the camera with the index CameraIdxCameraIdxCameraIdxcameraIdxcamera_idx in the calibration data model CalibDataIDCalibDataIDCalibDataIDcalibDataIDcalib_data_id. The parameter CameraIdxCameraIdxCameraIdxcameraIdxcamera_idx must be between 0 and NumCamerasNumCamerasNumCamerasnumCamerasnum_cameras-1 (NumCamerasNumCamerasNumCamerasnumCamerasnum_cameras is specified during model creation with create_calib_datacreate_calib_dataCreateCalibDataCreateCalibDatacreate_calib_data and can be queried with get_calib_dataget_calib_dataGetCalibDataGetCalibDataget_calib_data). If a camera with CameraIdxCameraIdxCameraIdxcameraIdxcamera_idx was already defined, its parameters are overwritten by the current ones (the camera is substituted). In this case, the selection which camera parameters are marked for optimization is reset and maybe has to be set again. Note that all NumCamerasNumCamerasNumCamerasnumCamerasnum_cameras cameras must be set to perform calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerascalibrate_cameras. The calibration procedure refines these initial parameters. You can find further information about the calibration process of different camera setups in Calibration.

The parameter CameraTypeCameraTypeCameraTypecameraTypecamera_type is only provided for backwards compatibility. The information about the camera type is contained in the first element of CameraParamCameraParamCameraParamcameraParamcamera_param. Therefore, CameraTypeCameraTypeCameraTypecameraTypecamera_type should be set either to its default value [] (the recommended option) or to the same value as the first element of CameraParamCameraParamCameraParamcameraParamcamera_param. In any other case an error is raised.

An overview of all available camera types and their respective parameters is given in CameraParamCameraParamCameraParamcameraParamcamera_param.

The camera type can be queried later by calling get_calib_dataget_calib_dataGetCalibDataGetCalibDataget_calib_data with the arguments ItemTypeItemTypeItemTypeitemTypeitem_type='camera'"camera""camera""camera""camera" and DataNameDataNameDataNamedataNamedata_name='type'"type""type""type""type". The initial camera parameters can be queried by calling get_calib_dataget_calib_dataGetCalibDataGetCalibDataget_calib_data with arguments ItemTypeItemTypeItemTypeitemTypeitem_type='camera'"camera""camera""camera""camera" and DataNameDataNameDataNamedataNamedata_name='init_params'"init_params""init_params""init_params""init_params".

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:

• CalibDataIDCalibDataIDCalibDataIDcalibDataIDcalib_data_id

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