1. A system for light detection and ranging, comprising:
a light source configured to emit a plurality of laser beams for determining a distance to an object in a three-dimensional environment;
a scanner having a plurality of scan axes and configured to direct the plurality of laser beams to the three-dimensional environment;
a detector configured to output a point cloud image comprising the distance to the object based on echoes of the plurality of laser beams; and
a controller coupled to the scanner and configured to generate a drive signal to cause the scanner to adjust a resolution for determining the distance in a region in a field of view based on a real-time condition.
