The supervisory service may receive an acceptance of the offer by the autonomous vehicle that includes an identifier for the autonomous vehicle. The supervisory service may identify one or more video streams of the parking area as associated with the autonomous vehicle based in part on a location of the autonomous vehicle in the parking area. The supervisory service may annotate the one or more identified video streams with metadata regarding a feature of the parking area. The supervisory service may send the annotated one or more video streams to the autonomous vehicle, wherein the autonomous vehicle uses the metadata of the annotated one or more video streams to avoid the feature of the parking area. ## Claims ### Claim 1 A method, comprising: sending, by a supervisory service of a parking area and to an autonomous vehicle, a light fidelity (Li-Fi) based advertisement indicative of an offer by the supervisory service to send video streams of the parking area to the autonomous vehicle; receiving, at the supervisory service, an acceptance of the offer by the autonomous vehicle that includes an identifier for the autonomous vehicle; identifying, by the supervisory service, one or more video streams of the parking area as associated with the autonomous vehicle based in part on a location of the autonomous vehicle in the parking area; annotating, by the supervisory service, the one or more identified video streams with metadata regarding a feature of the parking area; and sending, by the supervisory service, the annotated one or more video streams to the autonomous vehicle, wherein the autonomous vehicle uses the metadata of the annotated one or more video streams to avoid the feature of the parking area. ### Claim 2 (depends on 1) The method of claim 1, wherein the acceptance of the offer by the autonomous vehicle that includes the identifier for the autonomous vehicle is indicated by a pattern in emission of light from headlights of the autonomous vehicle, a Li-Fi transmitter of the autonomous vehicle, a light transmitter of the vehicle, or by infrared emission of the autonomous vehicle. ### Claim 3 (depends on 1) The method of claim 1, wherein the metadata indicates a length, width, area, volume, color, speed, acceleration, or direction of the feature of the parking area. ### Claim 4 (depends on 1) The method of claim 1, wherein using, by the autonomous vehicle, the metadata of the annotated one or more video streams to avoid the feature of the parking area comprises: performing, by the autonomous vehicle, at least one of image recognition or mapping processes with the metadata to determine a proximity of the autonomous vehicle in relation to the feature of the parking area. ### Claim 5 (depends on 1) The method of claim 1, wherein using, by the autonomous vehicle, the metadata of annotated one or more video streams to avoid the feature of the parking area: combining, by the autonomous vehicle, the metadata with sensor data that is collected by the autonomous vehicle. ### Claim 6 (depends on 1) The method of claim 1, wherein the metadata regarding the feature of the parking area is indicative of an occupied parking space or a destination parking spot, further wherein the autonomous vehicle avoids the occupied parking space. ### Claim 7 (depends on 1) The method of claim 1, wherein the metadata regarding the feature of the parking area is indicative of another vehicle in the parking area, further wherein the autonomous vehicle avoids the other vehicle. ### Claim 8 (depends on 1) The method of claim 1, wherein the metadata regarding the feature of the parking area is indicative of signage in the parking area, further wherein the autonomous vehicle avoids traveling in a direction different than indicated by the signage. ### Claim 9 (depends on 1) The method of claim 1, wherein a video stream of the video streams is collected by a camera of a drone. ### Claim 10 A method, comprising: receiving, by an autonomous vehicle and from a supervisory service of a parking area, a light fidelity (Li-Fi) based advertisement indicative of an offer by the supervisory service to send video streams of the parking area to the vehicle; sending, by the autonomous vehicle, an acceptance of the offer by the autonomous vehicle that includes an identifier for the autonomous vehicle; receiving, by the autonomous vehicle, one or more video streams annotated with metadata regarding a feature of the parking area, wherein the supervisory service identifies the annotated one or more video streams based in part on a location of the autonomous vehicle in the parking area and annotates the one or more video streams with metadata regarding the feature of the parking area;

a processor coupled to the network interfaces and configured to execute one or more processes; and a memory configured to store a process executable by the processor, the process when executed configured to: send a light fidelity (Li-Fi) based advertisement indicative of an offer by a supervisory service of a parking area to send video streams of the parking area to an autonomous vehicle; receive an acceptance of the offer by the autonomous vehicle that includes an identifier for the autonomous vehicle; identify one or more video streams of the parking area as associated with the autonomous vehicle based in part on a location of the autonomous vehicle in the parking area; annotate the one or more identified video streams with metadata regarding a feature of the parking area; and send the annotated one or more video streams to the autonomous vehicle, wherein the autonomous vehicle uses the metadata of the annotated one or more video streams to avoid the feature of the parking area. ### Claim 20 (depends on 19) The apparatus as in claim 19, wherein the acceptance of the offer by the autonomous vehicle that includes the identifier for the autonomous vehicle is indicated by a pattern in emission of light from headlights of the autonomous vehicle, a Li-Fi transmitter of the autonomous vehicle, a light transmitter of the vehicle, or by infrared emission of the autonomous vehicle.
