cam_par_pose_to_hom_mat3dT_cam_par_pose_to_hom_mat3dCamParPoseToHomMat3dCamParPoseToHomMat3dcam_par_pose_to_hom_mat3d — Convert internal camera parameters and a 3D pose into a 3×4
projection matrix.
Signature
def cam_par_pose_to_hom_mat3d(camera_param: Sequence[Union[int, float, str]], pose: Sequence[Union[int, float]]) -> Sequence[float]
Description
cam_par_pose_to_hom_mat3dcam_par_pose_to_hom_mat3dCamParPoseToHomMat3dCamParPoseToHomMat3dcam_par_pose_to_hom_mat3d converts the internal camera
parameters CameraParamCameraParamCameraParamcameraParamcamera_param and the 3D pose PosePosePoseposepose, which
represent the external camera parameters, into the 3×4 projection
matrix HomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d, which can be used to project points from
3D to 2D. The conversion can only be performed if the distortion
coefficients in CameraParamCameraParamCameraParamcameraParamcamera_param are 0. If necessary,
change_radial_distortion_cam_parchange_radial_distortion_cam_parChangeRadialDistortionCamParChangeRadialDistortionCamParchange_radial_distortion_cam_par must be used to achieve
this. The internal camera parameters and the pose are typically
obtained with calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerascalibrate_cameras.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
