cam_par_to_cam_matT_cam_par_to_cam_matCamParToCamMatCamParToCamMat (Operator)

Name

cam_par_to_cam_matT_cam_par_to_cam_matCamParToCamMatCamParToCamMat — Compute a camera matrix from internal camera parameters.

Signature

Description

cam_par_to_cam_matcam_par_to_cam_matCamParToCamMatCamParToCamMatCamParToCamMat computes the camera matrix CameraMatrixCameraMatrixCameraMatrixCameraMatrixcameraMatrix as well as the image width ImageWidthImageWidthImageWidthImageWidthimageWidth, and the image height ImageHeightImageHeightImageHeightImageHeightimageHeight from the internal camera parameters CameraParamCameraParamCameraParamCameraParamcameraParam. The internal camera parameters CameraParamCameraParamCameraParamCameraParamcameraParam can be determined with camera_calibrationcamera_calibrationCameraCalibrationCameraCalibrationCameraCalibration. cam_par_to_cam_matcam_par_to_cam_matCamParToCamMatCamParToCamMatCamParToCamMat converts this representation of the internal camera parameters into the representation used by stationary_camera_self_calibrationstationary_camera_self_calibrationStationaryCameraSelfCalibrationStationaryCameraSelfCalibrationStationaryCameraSelfCalibration. The conversion can only be performed if the camera is an area scan pinhole camera and the distortion coefficients in CameraParamCameraParamCameraParamCameraParamcameraParam are 0. If necessary, change_radial_distortion_cam_parchange_radial_distortion_cam_parChangeRadialDistortionCamParChangeRadialDistortionCamParChangeRadialDistortionCamPar must be used to set the distortion coefficients to 0.

Execution Information

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

Parameters

Example (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)

Result

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