Is there any requirement for the brand parameter in this file（vehicle_param.pb.txt）? The brand of my own car will report an error.

I defined my own car brand in calibration/data. After build, an error will be reported when starting dreamview, as shown below. When I changed the brand parameter to LINCOLN MKZ, it can be started successfully, but the brand parameter is required

[dajiba6]

have you defined the type in vehicle_config.proto?

[lq666666666]

No, is it only necessary to add my own brand in VehicleBrand and is there any configuration description? In addition, I would also like to ask if there is any document related to the calibration content of my car?

Yes, if you want to add new vehicle brand is one of the fields. You also need to modify other vehicle parameters, such as vehicle length, width, turning radius, etc.

After that, sensor calibration is required to obtain the position relationship of the sensors.
