Abstract
An autonomous vehicle including a projector and a sensor system configured to output data representative of an object in an environment exterior of the autonomous vehicle. The autonomous vehicle can further include a data store that stores height map data. A computing system of the autonomous vehicle can classify an object as a person and can detect an initial position of the person. Responsive to the detection, the computing system can calibrate a notification to be projected on a ground of the environment exterior of the autonomous vehicle. The notification is based on output of a transform from a position of the projector to the ground and the transform is applied based on the predefined height map of the ground. The notification can be projected adjacent the person. The notification may be configured to inform the person that the autonomous vehicle detects a position of the person.
