1. A light detection and ranging apparatus, comprising:
a light emitter configured to generate, according to a first electrical pulse signal, a first light signal comprising one or more pulses;
a receiver configured to receive a return light signal, wherein a controller in communication with the receiver is configured to generate one more points in a point cloud based on the return light signal, wherein the point cloud includes a set of points representing a partial surface of an object and a subsystem, configured to identify as noise a target point from the set of points representing the partial surface of the object by determining whether there is a coherence between the target point and a first neighboring point of the target point along a first direction and a coherence between the target point and a second neighboring point of the target point along a second direction, wherein the first neighboring point and the second neighboring point are from the set of points representing the partial surface of the object in the point cloud.
