描述

pose_to_hom_mat3dpose_to_hom_mat3dPoseToHomMat3dPoseToHomMat3dPoseToHomMat3dpose_to_hom_mat3d converts a 3D pose PosePosePosePoseposepose, e.g., the external camera parameters, into the equivalent homogeneous transformation matrix HomMat3DHomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d. For details about 3D poses and the corresponding transformation matrices please refer to create_posecreate_poseCreatePoseCreatePoseCreatePosecreate_pose。

A typical application of pose_to_hom_mat3dpose_to_hom_mat3dPoseToHomMat3dPoseToHomMat3dPoseToHomMat3dpose_to_hom_mat3d is that you want to further transform the pose, e.g., rotate or translate it using hom_mat3d_rotatehom_mat3d_rotateHomMat3dRotateHomMat3dRotateHomMat3dRotatehom_mat3d_rotate or hom_mat3d_translatehom_mat3d_translateHomMat3dTranslateHomMat3dTranslateHomMat3dTranslatehom_mat3d_translate。In case of the external camera parameters, this can be necessary if the calibration plate cannot be placed such that its coordinate system coincides with the desired world coordinate system.

参数

示例（HDevelop）

* Calibrate camera.
calibrate_cameras (CalibDataID,Error)
* Get reference pose (pose 2 of calibration object 0).
get_calib_data (CalibDataID, 'calib_obj_pose',\
                [0,2], 'pose', ObjInCameraPose)
*  Convert pose to homogeneous transformation matrix.
pose_to_hom_mat3d(ObjInCameraPose, cam_H_cal)
*  Rotate it 90 degrees around its y-axis to obtain a world coordinate system
*  whose y- and z-axis lie in the plane of the calibration plate while the
*  x-axis point 'upwards': cam_H_w = cam_H_cal * RotY(90).
hom_mat3d_identity(HomMat3DIdent)
hom_mat3d_rotate(HomMat3DIdent, rad(90), 'y', 0, 0, 0, \
                 HomMat3DRotateY)
hom_mat3d_compose(cam_H_cal, HomMat3DRotateY, cam_H_w)
* Convert transformed matrix back to pose.
hom_mat3d_to_pose (cam_H_w, Pose)
