Abstract: A detected displacement of a marker on a vehicle is determined based on image data captured while the vehicle traverses a displacement object of a ground surface. Then a health status of a suspension component of the vehicle is determined to be unhealthy based on comparing the detected displacement of the marker to a target displacement of the marker. The target displacement specifies displacement of the marker that indicates the suspension component is healthy. The vehicle is operated based on the suspension component being unhealthy.
