Name

cam_par_pose_to_hom_mat3dT_cam_par_pose_to_hom_mat3dCamParPoseToHomMat3dCamParPoseToHomMat3d — Convert internal camera parameters and a 3D pose into a 3×4 projection matrix.

Signature

Description

cam_par_pose_to_hom_mat3dcam_par_pose_to_hom_mat3dCamParPoseToHomMat3dCamParPoseToHomMat3dCamParPoseToHomMat3d converts the internal camera parameters CameraParamCameraParamCameraParamCameraParamcameraParam and the 3D pose PosePosePosePosepose, which represent the external camera parameters, into the 3×4 projection matrix HomMat3DHomMat3DHomMat3DHomMat3DhomMat3D, which can be used to project points from 3D to 2D. The conversion can only be performed if the distortion coefficients in CameraParamCameraParamCameraParamCameraParamcameraParam are 0. If necessary, change_radial_distortion_cam_parchange_radial_distortion_cam_parChangeRadialDistortionCamParChangeRadialDistortionCamParChangeRadialDistortionCamPar must be used to achieve this. The internal camera parameters and the pose are typically obtained with calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerasCalibrateCameras.

Execution Information

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