Claim 11:
12. A method for light detection and ranging, comprising:
emitting, by a light emitter, a first light signal according to an electrical pulse signal, the first light signal comprising one or more pulses;
receiving, by a receiver, one or more return light signals reflected by an object;
converting, by the receiver, the one or more return light signals into electrical signals, wherein said electrical signals are used to generate one or more points in a point cloud, wherein the point cloud includes a set of points representing a partial surface of the object; and
identifying 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.
