Abstract

A Lidar system is provided. The Lidar system comprise: a light source configured to emit a multi-pulse sequence to measure a distance between the Lidar system and a location in a three-dimensional environment, and the multi-pulse sequence comprises multiple pulses having a temporal profile; a photosensitive detector 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 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 pulses and the temporal profile.
