ADAPTIVE CODING FOR LIDAR SYSTEMS

Document Type and Number:

WIPO Patent Application WO/2020/000755

Kind Code:

A1

Abstract:

A Lidar system (100) is provided. The Lidar system (100) comprise: a light source (500) configured to emit a multi-pulse sequence (210) to measure a distance between the Lidar system (100) and a location in a three-dimensional environment, and the multi-pulse sequence (210) comprises multiple pulses (211) having a temporal profile; a photosensitive detector (51) configured to detect light pulses from the three-dimensional environment; and one or more processors configured to: determine a coding scheme comprising the temporal profile, wherein the coding scheme is determined dynamically based on one or more real-time conditions including an environment condition, a condition of the Lidar system (100) or a signal environment condition; and calculate the distance based on a time of flight of a sequence of detected light pulses, wherein the time of flight is determined by determining a match between the sequence of detected light pulse and the temporal profile.
