名称

write_cam_parT_write_cam_parWriteCamParWriteCamParwrite_cam_par — Write internal camera parameters into a file.

参数签名

write_cam_par( : : CameraParam, CamParFile : )

描述

write_cam_parwrite_cam_parWriteCamParWriteCamParWriteCamParwrite_cam_par stores the internal camera parameters CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param into a file specified by its file name CamParFileCamParFileCamParFileCamParFilecamParFilecam_par_file.

The number of values in CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param depends on the specified camera type. See the description of set_calib_data_cam_paramset_calib_data_cam_paramSetCalibDataCamParamSetCalibDataCamParamSetCalibDataCamParamset_calib_data_cam_param for a list of values and the chapter Calibration for details on camera types and camera parameters.

The default HALCON file extension for the camera parameters is 'dat'.

The internal camera parameters can be later read with read_cam_parread_cam_parReadCamParReadCamParReadCamParread_cam_par.

运行信息

结果

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