Abstract
A LIDAR system, preferably including one or more: optical emitters, optical detectors, beam directors, and/or processing modules. A method of LIDAR system operation, preferably including: determining a signal, outputting the signal, receiving a return signal, and/or analyzing the return signal.
Claims20
A method for environment mapping, comprising:
- generating a laser output representative of an output signal that encodes a code sequence, comprising modulating a carrier signal based on the code sequence;
- during a time period, transmitting the laser output into an environment;
- during the time period, at an optical sensor, receiving a return signal comprising a reflection, from an object within the environment, of the laser output;
- determining a sample indicative of a contiguous time window of the return signal;
- generating a filtered sample, comprising filtering the sample based on the code sequence;
- based on the filtered sample:
- determining an extremum of the filtered sample;
- and
- determining a delay time associated with the extremum;
- and
- based on the delay time, determining a relative location of the object.
