Hello! I would appreciate it if you could help me.

When the car uses lidar for SLAM, I found that the direction in rviz is different from the real world of 90°. It means that the car runs east-west but North-South in rviz.

The car is compsoed of STM32 and Jetson-nano.

I guess something’s wrong with IMU？But I’m not sure. I don’t know how to solve this problem.

My guess is the problem lies somewhere in your URDF of your car. The URDF describes how the IMU link is connected to the base_link of the car. I'm guessing it's rotated 90° with comparison to what you have on the real car.
