get_camera_setup_param — Get generic camera setup model parameters.
The operator get_camera_setup_param can be used to inspect diverse generic parameters of the camera setup model CameraSetupModelID. Two types of parameters can be queried with this operator:
By setting CameraIdx to 'general' and GenParamName to one of the following values, general camera setup parameters are returned in GenParamValue:
Number of cameras described in the model. The number of cameras is fixed with the creation of the camera setup model and cannot be changed after that (see create_camera_setup_model).
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_cameras.
Returns the index of the camera that has been defined as reference camera within the system. If no reference camera has been specified using set_camera_setup_param, the index 0 is returned. If the coordinate system has been moved by setting a pose with the parameter 'coord_transf_pose' in set_camera_setup_param, the origin of the coordinate system is not located in any of the available cameras. Therefore, the index -1 is returned.
Returns the pose in which the coordinate system of the setup has been moved. Please note that after setting a reference camera with set_camera_setup_param, the pose of this camera is returned. Adjusting this coordinate system subsequently using the parameter 'coord_transf_pose' in set_camera_setup_param yields a pose that corresponds to the location and orientation of the desired coordinate system relative to the current one.
By setting CameraIdx to a valid setup camera index (a value between 0 and NumCameras-1) and GenParamName to one of the following values, camera-specific parameters are returned in GenParamValue:
Camera type (see set_camera_setup_cam_param).
A tuple with internal camera parameters. The length of the tuple depends on the camera type.
A tuple representing the standard deviations of the internal camera parameters. The length of the tuple depends on the camera type.
A tuple representing the covariance matrix if the internal camera parameters. The length of the tuple depends on the camera type.
Camera pose relative to the setup's coordinate system (see create_camera_setup_model for more details).
Note that the camera needs to be set first by set_camera_setup_cam_param, before any of its parameters can be inspected by get_camera_setup_param. If CameraIdx is an index of an undefined camera, the operator returns an error.
Handle to the camera setup model.
Index of the camera in the setup.
