Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the present invention, rather than Full examples.

[0026] The embodiment of the present invention discloses a method for eliminating noise points of a high-resolution solid-state laser radar point cloud, including the following steps:

[0027] Step 1: Carry out image scanning and acquisition;

[0028] Step 2: If figure 1 As shown, set a scanning area on each scanned image, and control the scanning area to slide regularly in the frame, traverse all valid points in this scanning area, the number is P, and obtain Max tof and Min tof , are the maximum value of Tof and the minimum value of Tof respectively;

[0029] Step 3: Set the threshold G, if (Max tof -Min tof )tof -Min tof )≥G, it is determined that th...

Abstract

The invention provides a method for eliminating noise points of high-resolution solid-state laser radar point cloud, which includes image scanning and acquisition; setting a scanning area on each frame of the scanned image, and controlling the scanning area to slide regularly within the frame , traverse all valid points in the frame data, and determine whether the points in the scanning area are suspected noise points; if all points in the scanning area are suspected drawing points and singular points, set a value W; if N×W >P, all points in the area are considered to be non-drawing points and singular points; if N×W

Description

technical field [0001] The invention relates to a method for eliminating noise points of a high-resolution solid-state laser radar point cloud Background technique [0002] Due to the inherent characteristics of solid-state lidar, when the laser spot hits the edge of the object, if the distance between the object and the background is within 0 to 2.5 meters, a waterfall-like gap will appear between the object point cloud and the background point cloud. The point cloud is called the drawing point. If the object and the background exceed the range of 2.5 meters, the unstable jumping point on the edge of the object is called a singular point. These two types of points will seriously affect the accuracy of radar detection and point cloud quality. Contents of the invention [0003] The present invention provides a method for removing noise points of high-resolution solid-state laser radar point clouds, so as to at least solve the influence of drawing points, singular points a...
