What are the requirements for sensor configuration in using Autoware?

Hi!

What are the requirements for sensor configuration in using Autoware?

I am trying to build autonomous driving capability for my own robot and would like to know what kind of sensors I need to use Autoware.
I went through the Autoware Document but could not find any.

It seems that LiDAR is required for ndt_scan_matcher, but how about other sensors such as IMU, odometry, GNSS, or camera?

Thank you in advance.

Thanks for your question!
Unfortunately, there is no documentation about the whole sensing policy just for now. 🤕

The sensing policy around the localization module is as follows.

LiDAR pointcloud ( sensor_msgs/PointCloud2 ) is mandatory.

Vehicle Twist ( geometry_msgs/TwistWithCovarianceStamped ) is mandatory.

IMU ( sensor_msgs/Imu ) is not mandatory, but it can be used with gyro_odometer to improve the accuracy of Vehicle Twist.

GNSS ( geometry_msgs/PoseWithCovarianceStamped ) is not mandatory, but can be used with pose_initializer for automatic initial position estimation.

The basic idea can be found at the following URL, the previous AutowareArchitectureProposal documents.

Thanks a lot! This fully answers my question.
