Signature

Description

The operator get_camera_setup_paramget_camera_setup_paramGetCameraSetupParamget_camera_setup_paramGetCameraSetupParamGetCameraSetupParam can be used to inspect diverse generic parameters of the camera setup model CameraSetupModelIDCameraSetupModelIDCameraSetupModelIDCameraSetupModelIDCameraSetupModelIDcameraSetupModelID. Two types of parameters can be queried with this operator:

General parameters:

By setting CameraIdxCameraIdxCameraIdxCameraIdxCameraIdxcameraIdx to 'general'"general""general""general""general""general" and ParamNameParamNameParamNameParamNameParamNameparamName to one of the following values, general camera setup parameters are returned in ParamValueParamValueParamValueParamValueParamValueparamValue:

'num_cameras'"num_cameras""num_cameras""num_cameras""num_cameras""num_cameras":

Number of cameras described in the model.

'camera_calib_error'"camera_calib_error""camera_calib_error""camera_calib_error""camera_calib_error""camera_calib_error":

The root mean square error (RMSE) of the back projection of the optimization of the camera system. This error is identical with the error returned by calibrate_camerascalibrate_camerasCalibrateCamerascalibrate_camerasCalibrateCamerasCalibrateCameras.

The number of cameras is fixed with the creation of the camera setup model and cannot be changed after that (see create_camera_setup_modelcreate_camera_setup_modelCreateCameraSetupModelcreate_camera_setup_modelCreateCameraSetupModelCreateCameraSetupModel).

Camera parameters:

By setting CameraIdxCameraIdxCameraIdxCameraIdxCameraIdxcameraIdx to a valid setup camera index (a value between 0 and NumCameras-1) and ParamNameParamNameParamNameParamNameParamNameparamName to one of the following values, camera-specific parameters are returned in ParamValueParamValueParamValueParamValueParamValueparamValue:

'type'"type""type""type""type""type":

Camera type (see set_camera_setup_cam_paramset_camera_setup_cam_paramSetCameraSetupCamParamset_camera_setup_cam_paramSetCameraSetupCamParamSetCameraSetupCamParam).

'params'"params""params""params""params""params":

A tuple with internal camera parameters. The length of the tuple depends on the camera type.

'params_deviations'"params_deviations""params_deviations""params_deviations""params_deviations""params_deviations":

A tuple representing the standard deviations of the internal camera parameters. The length of the tuple depends on the camera type.

'params_covariances'"params_covariances""params_covariances""params_covariances""params_covariances""params_covariances":

A tuple representing the covariance matrix if the internal camera parameters. The length of the tuple depends on the camera type.

'pose'"pose""pose""pose""pose""pose":

Camera pose relative to the setup's coordinate system (see create_camera_setup_modelcreate_camera_setup_modelCreateCameraSetupModelcreate_camera_setup_modelCreateCameraSetupModelCreateCameraSetupModel for more details).

Note that the camera needs to be set first by set_camera_setup_cam_paramset_camera_setup_cam_paramSetCameraSetupCamParamset_camera_setup_cam_paramSetCameraSetupCamParamSetCameraSetupCamParam, before any of its parameters can be inspected by get_camera_setup_paramget_camera_setup_paramGetCameraSetupParamget_camera_setup_paramGetCameraSetupParamGetCameraSetupParam. If CameraIdxCameraIdxCameraIdxCameraIdxCameraIdxcameraIdx is an index of an undefined camera, the operator returns an error.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
