签名

read_cam_par( : : CamParFile : CameraParam)

描述

read_cam_parread_cam_parReadCamParReadCamParReadCamParread_cam_par reads the internal camera parameters CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param from a file with name CamParFileCamParFileCamParFileCamParFilecamParFilecam_par_file. The file must have been written by write_cam_parwrite_cam_parWriteCamParWriteCamParWriteCamParwrite_cam_par。

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

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 标定 for details on camera types and camera parameters.
