METHOD AND SYSTEM FOR ENCODING AND DECODING LiDAR

A method, comprising:

• transmitting, with a light source, a pulse group signal, wherein the pulse group signal comprises a plurality of pulses having a characteristic;
• receiving a returned pulse group signal, wherein the returned pulse group signal corresponds to the transmitted pulse group signal scattered from a surface;
• correlating the returned pulse group signal with the transmitted pulse group signal based on the characteristic;
• determining a time difference between (1) a time associated with the transmitted pulse group signal and (2) a time associated with the returned pulse group signal;
• and
• calculating a distance from the light source to the surface based on the time difference.

A light detection and ranging (LiDAR) scanning system, comprising:

• a light source, wherein the light source is configured to transmit a pulse group signal,
• wherein the pulse group signal comprises a plurality of pulses having a characteristic;
• a light detector configured to receive a returned pulse group signal, wherein the returned pulse group signal corresponds to the transmitted pulse group signal scattered from a surface;
• and
• a microprocessor electrically coupled to the light source and the light detector, wherein the microprocessor is configured to:
• correlate the returned pulse group signal with the transmitted pulse group signal based on the characteristic;
• determine a time difference between (1) a time associated with the transmitted pulse group signal and (2) a time associated with the returned pulse group signal;
• and
• calculate a distance from the light source to the surface based on the time difference.
