A system and method for communicating data using lidar, the method being carried out by a lidar communication system, the method including: activating a data communication mode of a lidar unit; preparing data for communication using lidar; after activating the data communication mode, emitting a plurality of light pulses using the lidar unit, wherein the plurality of light pulses are emitted in a manner so as to convey the prepared data to an external lidar communication device; and receiving an acknowledgment message, wherein the acknowledgment message indicates receipt of the prepared data at the external lidar communication device.

Lidar object detection and data communications

The present application generally relates communications and hazard avoidance within a monitored driving environment. More specifically, the application teaches a system for improved target object detection in a vehicle equipped with a laser detection and ranging LIDAR system by determining a plurality of ranges in response to a plurality of light pulse reflections and determining a false target indication by exploiting the expected continuity of surfaces in the environment.

Method and apparatus crosstalk and multipath noise reduction in a LIDAR system

Systems and methods of mapping traffic related objects. In one embodiment, a method includes: receiving image sensor data relating to an environment associated with a vehicle; receiving lidar sensor data relating to the environment associated with the vehicle; selecting, by a processor, at least one image region including a traffic related object from the image sensor data; selectively filtering, by a processor, the at least one image region based on the lidar sensor data; and generating, by a processor, a composite map including a representation of the traffic related object superimposed upon a defined map of the environment based on the selectively filtering.
