描述

cam_par_to_cam_matcam_par_to_cam_matCamParToCamMatCamParToCamMatCamParToCamMatcam_par_to_cam_mat computes the camera matrix CameraMatrixCameraMatrixCameraMatrixCameraMatrixcameraMatrixcamera_matrix as well as the image width ImageWidthImageWidthImageWidthImageWidthimageWidthimage_width, and the image height ImageHeightImageHeightImageHeightImageHeightimageHeightimage_height from the internal camera parameters CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param. The internal camera parameters CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param can be determined with camera_calibrationcamera_calibrationCameraCalibrationCameraCalibrationCameraCalibrationcamera_calibration. cam_par_to_cam_matcam_par_to_cam_matCamParToCamMatCamParToCamMatCamParToCamMatcam_par_to_cam_mat converts this representation of the internal camera parameters into the representation used by stationary_camera_self_calibrationstationary_camera_self_calibrationStationaryCameraSelfCalibrationStationaryCameraSelfCalibrationStationaryCameraSelfCalibrationstationary_camera_self_calibration. The conversion can only be performed if the camera is an area scan pinhole camera and the distortion coefficients in CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param are 0. If necessary, change_radial_distortion_cam_parchange_radial_distortion_cam_parChangeRadialDistortionCamParChangeRadialDistortionCamParChangeRadialDistortionCamParchange_radial_distortion_cam_par must be used to set the distortion coefficients to 0.

执行信息

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

参数

CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param (input_control) campar → (real / integer / string)

Internal camera parameters.

CameraMatrixCameraMatrixCameraMatrixCameraMatrixcameraMatrixcamera_matrix (output_control) hom_mat2d → (real)

3x3 projective camera matrix that corresponds to CameraParamCameraParamCameraParamCameraParamcameraParamcamera_param.

ImageWidthImageWidthImageWidthImageWidthimageWidthimage_width (output_control) extent.x → (integer)

Width of the images that correspond to CameraMatrixCameraMatrixCameraMatrixCameraMatrixcameraMatrixcamera_matrix.

Assertion: ImageWidth > 0

ImageHeightImageHeightImageHeightImageHeightimageHeightimage_height (output_control) extent.y → (integer)

Height of the images that correspond to CameraMatrixCameraMatrixCameraMatrixCameraMatrixcameraMatrixcamera_matrix.

Assertion: ImageHeight > 0

示例（HDevelop）

* For the input data to calibrate_cameras, please refer to the
* example for calibrate_cameras.
calibrate_cameras (CalibDataID, Error)
get_calib_data (CalibDataID, 'camera', 0, 'params', CameraParam)
cam_par_to_cam_mat (CameraParam, CameraMatrix, ImageWidth, ImageHeight)

* Alternatively, the following calls can be used.
change_radial_distortion_cam_par ('adaptive', CameraParam, 0, CamParamOut)
cam_par_to_cam_mat (CamParamOut, CameraMatrix, ImageWidth, ImageHeight)

结果

If the parameters are valid, the operator cam_par_to_cam_matcam_par_to_cam_matCamParToCamMatCamParToCamMatCamParToCamMatcam_par_to_cam_mat returns the value 2 ( H_MSG_TRUE) . If necessary an exception is raised.
