Your question is Road Normal From Lidar. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Given lidar detections, how would you determine where the road is and how would you compute the normal vector to an object?
Explain the pipeline you would build to ingest point-cloud detections, segment road points, and estimate surface normals. Focus on the transformations, quality checks, and failure handling you would use in a production data pipeline.
