名称

write_cam_parT_write_cam_parWriteCamParWriteCamParwrite_cam_par — 将内部相机参数写入文件。

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 标定 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。

参数

CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param (输入控制) campar → (real / integer / string)

Internal camera parameters.

File name of internal camera parameters.

默认值： 'campar.dat' "campar.dat" "campar.dat" "campar.dat" "campar.dat" "campar.dat"

示例（HDevelop）

*
* Calibrate the camera.
*
StartCamPar := ['area_scan_division', 0.016, 0, 0.0000074, 0.0000074, \
                326, 247, 652, 494]
create_calib_data ('calibration_object', 1, 1, CalibDataID)
set_calib_data_cam_param (CalibDataID, 0, [], StartCamPar)
set_calib_data_calib_object (CalibDataID, 0, 'caltab_30mm.descr')
NumImages := 10
for I := 1 to NumImages by 1
  read_image (Image, '3d_machine_vision/calib/calib_' + I$'02d')
  find_calib_object (Image, CalibDataID, 0, 0, I, [], [])
  get_calib_data_observ_contours (Caltab, CalibDataID, 'caltab', 0, 0, I)
endfor
calibrate_cameras (CalibDataID, Error)
get_calib_data (CalibDataID, 'camera', 0, 'params', CamParam)
* Write the internal camera parameters to a file.
write_cam_par (CamParam, 'camera_parameters.dat')

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。如有必要，则抛出异常。
