read_cam_parT_read_cam_parReadCamParReadCamPar (Operator)
Name
read_cam_parT_read_cam_parReadCamParReadCamPar — Read internal camera parameters from a file.
Signature
Description
read_cam_parread_cam_parReadCamParReadCamParReadCamPar reads the internal camera parameters
CameraParamCameraParamCameraParamCameraParamcameraParam from a file with name CamParFileCamParFileCamParFileCamParFilecamParFile. The
file must have been written by write_cam_parwrite_cam_parWriteCamParWriteCamParWriteCamPar.
The default HALCON file extension for the camera parameters is
'dat'.
The number of values in CameraParamCameraParamCameraParamCameraParamcameraParam depends on the
specified camera type. See the description of
set_calib_data_cam_paramset_calib_data_cam_paramSetCalibDataCamParamSetCalibDataCamParamSetCalibDataCamParam for a list of values and the chapter
Calibration for details on camera types and camera
parameters.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

Result
read_cam_parread_cam_parReadCamParReadCamParReadCamPar returns 2 (H_MSG_TRUE) if all parameter values are
correct and the file has been read successfully. If necessary an
exception is raised.
