Signature

Description

The operator set_calib_data_calib_objectset_calib_data_calib_objectSetCalibDataCalibObjectset_calib_data_calib_objectSetCalibDataCalibObjectSetCalibDataCalibObject defines the calibration object with the index CalibObjIdxCalibObjIdxCalibObjIdxCalibObjIdxCalibObjIdxcalibObjIdx in the camera calibration data model CalibDataIDCalibDataIDCalibDataIDCalibDataIDCalibDataIDcalibDataID. The index must be between 0 and NumCalibObjects-1 (NumCalibObjects is specified during model creation with create_calib_datacreate_calib_dataCreateCalibDatacreate_calib_dataCreateCalibDataCreateCalibData and can be queried with get_calib_dataget_calib_dataGetCalibDataget_calib_dataGetCalibDataGetCalibData).

If a calibration object description with index CalibObjIdxCalibObjIdxCalibObjIdxCalibObjIdxCalibObjIdxcalibObjIdx is already defined, then the current object description overwrites it (the description is 'substituted'). Note that all NumCalibObjects calibration objects must be set to perform calibrate_camerascalibrate_camerasCalibrateCamerascalibrate_camerasCalibrateCamerasCalibrateCameras.

The parameter CalibObjDescrCalibObjDescrCalibObjDescrCalibObjDescrCalibObjDescrcalibObjDescr can be used in two ways:

as a file name:

it specifies a calibration object description file. The supported format is defined with gen_caltabgen_caltabGenCaltabgen_caltabGenCaltabGenCaltab. Only the circles' center coordinates are used from this file similar to caltab_pointscaltab_pointsCaltabPointscaltab_pointsCaltabPointsCaltabPoints.

as a numerical tuple:

it specifies the 3D coordinates of all points of the calibration object. All X, Y, and Z coordinates, respectively, of all points must be packed sequentially in the tuple in form: [X, Y, Z], i.e., [X1, ..., Xn, Y1, ..., Yn, Z1, ..., Zn], where |X| = |Y| = |Z| and all coordinates are in meters.

To query the calibration objects parameters stored earlier in a calibration data model, use get_calib_dataget_calib_dataGetCalibDataget_calib_dataGetCalibDataGetCalibData.

Attention

A camera calibration data model CalibDataID cannot be shared between two or more user's threads. Different camera calibration data models can be used independently and safely in different threads.

Parallelization

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