The invention discloses a noisy point identifying method capable of being used for a laser radar. The noisy point identifying method comprises the steps: S201, point cloud obtained through the laser radar is received; S202, the reflectivity and at least one of continuity parameters of a point in the point cloud, and the distance between the point and the laser radar are obtained; and S203, whetherthe point is a noisy point or not is judged at least according to the reflectivity, at least one of the continuity parameters and the distance.
