How could I get the IMU data

[Ultramarine1939-syujie]

I've bought a gemini2,and The dealer told me that it has a built-in IMU, but it is not clear how to obtain the IMU data through ROS.
I'm working on ubuntu20.04-noetic

@Ultramarine1939-syujie You have to modify launch file

<arg name="enable_accel" default="true"/>
<arg name="enable_gyro" default="true"/>
<arg name ="enable_sync_output_accel_gyro" default = "true" />
..
..
..

<param name="enable_sync_output_accel_gyro" value="$(arg enable_sync_output_accel_gyro)"/>

which will publish synchronized data stream of acceleration and gyroscope to the topic camera/gyro_accel/sample
