1. A method for processing a point cloud generated by a light detection and ranging system, comprising:
receiving a first measurement generated by the light detection and ranging system;
retrieving a plurality of second measurements that are adjacent to the first measurement;
calculating a first parameter by using a distance of the first measurement and distances of the plurality of the second measurements, the first parameter indicating a degree of continuum of the first measurement relative to the plurality of the second measurements; and
determining whether the first measurement represents a measurement of noises by using the first parameter.
