Can I use Roadrunner to import point cloud file in PCD format and export it to Opendrive high precision map XODR format? If so, how does it work? Looking forward to your reply。

You can use the point cloud (.las) and the elevation (.tif) file as a reference. Its like a 3D background image, where you can "lay down" roads with high accurecy. After the modeling, you can export it as Opendrive.

I would like to know the same thing. Can you input coordinates to exactly layout the roads?
I have the road isolated in blender as a mesh. If I just could use this mesh to generate an .xodr it would solve all my problems.
Thank you :)

1. condition
For the Point Cloud Tool to properly load PCD files, the files must have these properties in their headers:
  • FIELDS x y z — These fields must be and .SIZE 4TYPE F
  • DATA — The data type must be , , or.asciibinary binary_compressed
If the file specifies colors for the points, it must also contain an or field with these properties:intensityrgba
  • FIELDS intensity — This field must be and .SIZE 4TYPE F
  • FIELDS rgba — This field must be and .SIZE 4TYPE U
To toggle display of point clouds, select View > Point Clouds on the menu bar or press the F6 key.
2.load to roadrunner
3. click menu of view select Point Cloud
4.drag the point cloud file to workspace window
...
5.select "Sorld Settings Tool" set the display area（important）
you should set Workspace big enough, biger than you point cloud max(x,y)，or not dispaly if you map point value (x,y) is big and you set workspace is small.
you can set the Workspace area(x,y) to (3000000, 30000000), not recommend.
