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


index of the observing camera


index of the observed calibration object


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 CalibObjIdxCalibObjIdxCalibObjIdxCalibObjIdxcalibObjIdx, the corresponding observation data is replaced by the new one. Of course, the same index can be assigned to poses of different calibration objects.

RowRowRowRowrow, ColumnColumnColumnColumncolumn, IndexIndexIndexIndexindex:

Extracted image coordinates and corresponding index of the calibration marks of the calibration object. RowRowRowRowrow and ColumnColumnColumnColumncolumn are tuples containing the same number of elements. IndexIndexIndexIndexindex can either contain a tuple (of the same length) or the value '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.


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_objectFindCalibObjectFindCalibObjectFindCalibObject instead of set_calib_data_observ_pointsset_calib_data_observ_pointsSetCalibDataObservPointsSetCalibDataObservPointsSetCalibDataObservPoints, since the contour information, which it stores in the calibration data model, enables a more precise calibration procedure with calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerasCalibrateCameras.

The observation data can be accessed later by calling get_calib_data_observ_pointsget_calib_data_observ_pointsGetCalibDataObservPointsGetCalibDataObservPointsGetCalibDataObservPoints using the same values for the arguments CameraIdxCameraIdxCameraIdxCameraIdxcameraIdx, CalibObjIdxCalibObjIdxCalibObjIdxCalibObjIdxcalibObjIdx, and CalibObjPoseIdxCalibObjPoseIdxCalibObjPoseIdxCalibObjPoseIdxcalibObjPoseIdx.
