Transformation data for robot_localization

[ROSnew]

Hello.
I want to run robot_localization with LOAM integrated_to_init odometry and IMU data.
I have transformation info between LIDAR and IMU devices.
Results of LOAM publish with
_laserOdometry2.header.frame_id = "camera_init";
_laserOdometry2.child_frame_id = "camera"

So, should I add new transformation node between LIDAR and "camera" (or "camera init"). Which? Or i need replace "camera" (or "camera_init") to "lidar" duting publish in TransformMaintenance.cpp ?
And also, should i add others new tranformations?

And how it should looks as result?
