Description

For a calibration model of type CalibSetupCalibSetupCalibSetupCalibSetupcalibSetupcalib_setup='calibration_object'"calibration_object""calibration_object""calibration_object""calibration_object""calibration_object" (see create_calib_datacreate_calib_dataCreateCalibDataCreateCalibDataCreateCalibDatacreate_calib_data), cameras are calibrated based on so-called observations of calibration objects. With set_calib_data_observ_pointsset_calib_data_observ_pointsSetCalibDataObservPointsSetCalibDataObservPointsSetCalibDataObservPointsset_calib_data_observ_points, you store such an observation in the calibration data model CalibDataIDCalibDataIDCalibDataIDCalibDataIDcalibDataIDcalib_data_id. An observation consists of the following data:

CameraIdxCameraIdxCameraIdxCameraIdxcameraIdxcamera_idx:

index of the observing camera

CalibObjIdxCalibObjIdxCalibObjIdxCalibObjIdxcalibObjIdxcalib_obj_idx:

index of the observed calibration object

CalibObjPoseIdxCalibObjPoseIdxCalibObjPoseIdxCalibObjPoseIdxcalibObjPoseIdxcalib_obj_pose_idx:

index of the observed pose of the calibration object. You can choose it freely, without following a strict order. If you specify an index that already exists for the calibration object CalibObjIdxCalibObjIdxCalibObjIdxCalibObjIdxcalibObjIdxcalib_obj_idx, the corresponding observation data is replaced by the new one. Of course, the same index can be assigned to poses of different calibration objects.

RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn, IndexIndexIndexIndexindexindex:

Extracted image coordinates and corresponding index of the calibration marks of the calibration object. RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn are tuples containing the same number of elements. IndexIndexIndexIndexindexindex can either contain a tuple (of the same length) or the value 'all'"all""all""all""all""all", indicating that the points [Row, Column] correspond in a one-to-one relation to the calibration marks of the calibration object. If the number of row or column coordinates does not match the number of calibration marks, a corresponding error message is returned.

PosePosePosePoseposepose:

A roughly estimated pose of the observed calibration object relative to observing camera.

If you are using the HALCON calibration plate, it is recommended to use find_calib_objectfind_calib_objectFindCalibObjectFindCalibObjectFindCalibObjectfind_calib_object instead of set_calib_data_observ_pointsset_calib_data_observ_pointsSetCalibDataObservPointsSetCalibDataObservPointsSetCalibDataObservPointsset_calib_data_observ_points, since the contour information, which it stores in the calibration data model, enables a more precise calibration procedure with calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerasCalibrateCamerascalibrate_cameras.

The observation data can be accessed later by calling get_calib_data_observ_pointsget_calib_data_observ_pointsGetCalibDataObservPointsGetCalibDataObservPointsGetCalibDataObservPointsget_calib_data_observ_points using the same values for the arguments CameraIdxCameraIdxCameraIdxCameraIdxcameraIdxcamera_idx, CalibObjIdxCalibObjIdxCalibObjIdxCalibObjIdxcalibObjIdxcalib_obj_idx, and CalibObjPoseIdxCalibObjPoseIdxCalibObjPoseIdxCalibObjPoseIdxcalibObjPoseIdxcalib_obj_pose_idx.

Execution Information

This operator modifies the state of the following input parameter:

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