1. A method for foveated imaging in lidar systems, the method comprising:

  • obtaining a model for foveated imaging in a lidar system operating in a vehicle, the model indicating, for each of a plurality of road conditions or maneuvers, one or more respective regions of interest within a field of regard of the lidar system in which the lidar system is to obtain data at higher quantity and/or quality relative to other regions within the field of regard;

    emitting light pulses by a light source in the lidar system at a certain pulse rate;

    scanning, by a scanner in the lidar system, the field of regard of the lidar system, in accordance with a certain scan pattern at a certain scan speed, including directing the light pulses toward different points within the field of regard;

    determining at least one of a road condition or an upcoming maneuver of the vehicle;

    applying the road condition or the upcoming maneuver to the model to identify a region of interest within the field of regard; and

    modifying at least one operational parameter of the lidar system to obtain data at higher quantity and/or quality within the identified region of interest, relative to other regions within the field of regard.
