This is the problem. There is a camera on uav and try to detect and send pose of the tag. The detected tag is at center for both images but one of them gives different coordinates (e.g (3,0,0) should be (0,0,0) ) because of the roll angle. I want to transform (rotate) the pose of the tag by using roll-pitch-yaw angles coming from IMU. Something like transforming from cameraframe --> worldframe but by using angles not by frame_name.

BRİEF : I have a pose and want to transform by using angles not frame name. Not like this

transform = tf_buffer.lookup_transform(target_frame,
                                   pose_stamped_to_transform.header.frame_id, #source frame
                                   rospy.Time(0), #get the tf at first available time
                                   rospy.Duration(1.0)) #wait for 1 second
pose_transformed = tf2_geometry_msgs.do_transform_pose(pose_stamped, transform)

This is a solution I found but doesn't work for me because ı don't want transform one frame to another. I want to transform by using angles.

This is the another solution which I tried but not sure is it a a proper way to do this..

    mpose = PoseStamped()

    mpose.pose.position.x = 3
    mpose.pose.position.y = 0
    mpose.pose.position.z = 0

    mpose.pose.orientation.x = 0
    mpose.pose.orientation.y = 0
    mpose.pose.orientation.z = 0
    mpose.pose.orientation.w = 0


    v = Vector3Stamped()
    v.vector.x = 3.0
    v.vector.y = 0.0
    v.vector.z = 0.0

    static_transformStamped = geometry_msgs.msg.TransformStamped()

    static_transformStamped.transform.translation.x = 0.0
    static_transformStamped.transform.translation.y = 0.0
    static_transformStamped.transform.translation.z = 0.0

    quat = tf.transformations.quaternion_from_euler(30.0, 0.0, 0.0)
    static_transformStamped.transform.rotation.x = quat[0]
    static_transformStamped.transform.rotation.y = quat[1]
    static_transformStamped.transform.rotation.z = quat[2]
    static_transformStamped.transform.rotation.w = quat[3]

    pose_transformed = tf2_geometry_msgs.do_transform_pose(mpose, static_transformStamped)
    #  I only need to convert x-y-z so,  can also do vector transform.
    pose_transformed = tf2_geometry_msgs.do_transform_vector3(v, static_transformStamped)
