Lidar based communication
Systems and methods for performing operations based on LIDAR communications are described. An example device may include one or more processors and a memory coupled to the one or more processors. The memory includes instructions that, when executed by the one or more processors, cause the device to receive data associated with a modulated optical signal emitted by a transmitter of a first LIDAR device and received by a receiver of a second LIDAR device coupled to a vehicle and the device, generate a rendering of an environment of the vehicle based on information from one or more LIDAR devices coupled to the vehicle, and update the rendering based on the received data. Updating the rendering includes updating an object rendering of an object in the environment of the vehicle. The instructions further cause the device to provide the updated rendering for display on a display coupled to the vehicle.
1. A device, comprising:
one or more processors; and
a memory coupled to the one or more processors, the memory including instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
causing a transmitter to transmit a first modulated optical signal to a first light detection and ranging (LIDAR) device coupled to a vehicle, wherein the transmitter is coupled to infrastructure, and wherein the first modulated optical signal includes an optical carrier signal modulated to include a data signal.
2. The device of claim 1 , wherein the infrastructure comprises at least one of a toll booth, a road construction area, a tunnel entrance, a traffic signal, a charging station, an entry gate, or a stand.
3. The device of claim 1 , wherein the transmitter is part of a second LIDAR device coupled to the infrastructure.
4. The device of claim 1 , wherein the data signal includes a transmitter identification.
5. The device of claim 1 , wherein the data signal includes an indication of a location of the infrastructure.
6. The device of claim 1 , wherein the data signal includes operating parameters for the transmitter.
7. The device of claim 1 , wherein data signal indicates restrictions on entering a limited access area.
8. The device of claim 7 , wherein the limited access area comprises at least one of a tunnel, a hospital ambulance entrance, handicap parking space, a high occupancy vehicle (HOV) lane, a parking area, or a portion of a city.
9. The device of claim 7 , wherein the infrastructure controls access to the limited access area.
10. The device of claim 1 , wherein data signal indicates a toll for entering an area.
11. The device of claim 10 , wherein the area comprises at least one of a bridge, a lane, or a portion of a city.
12. The device of claim 10 , wherein the infrastructure is a toll booth.
13. The device of claim 1 , wherein the data signal includes information regarding at least one of a missing vehicle, a stolen vehicle, or an offline vehicle.
14. The device of claim 1 , wherein the data signal hails the vehicle for a requested ride.
15. The device of claim 1 , wherein the data signal includes a notification to the vehicle.
16. The device of claim 15 , wherein the notification relates to at least one of an emergency vehicle, a road hazard, a school crossing zone, a speed limit change, a construction zone, a traffic accident, or a traffic obstruction.
17. The device of claim 1 , wherein the infrastructure is associated with a parking area, and wherein the data signal indicates available parking spaces in the parking area.
18. The device of claim 1 , wherein the infrastructure is associated with a parking area, and wherein the data signal indicates a fee to be charged for parking in the parking area.
19. The device of claim 1 , wherein the operations further comprise:
receiving data associated with a second modulated optical signal emitted by the first LIDAR device and received by a detector, wherein the detector is coupled to the infrastructure, and wherein the second modulated optical signal is responsive to the first modulated optical signal.
20. A non-transitory computer readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
causing a transmitter to transmit a first modulated optical signal to a first light detection and ranging (LIDAR) device coupled to a vehicle, wherein the transmitter is coupled to infrastructure, and wherein the first modulated optical signal includes an optical carrier signal modulated to include a data signal.
