Abstract

The invention discloses a sunshine noise filtering method based on a laser head, a chip and a robot, and the method comprises the following steps: S1, enabling the robot to control the laser head to work, and then obtaining laser data; S2, enabling the robot to acquire line segments and data points in the laser data; S3, enabling the robot to judge whether the line segment is a sunshine line segment or not, and if yes, executing the step S4; S4, filtering discrete points in the sunshine line segments and the data points by the robot, wherein the sunshine line segment is a line segment composedof sunshine noisy points. According to the method, the robot can effectively filter sunlight noise points in the laser data, the detection accuracy of the robot is improved, the influence of the environment on the use of the robot is reduced, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of intelligent robots, in particular to a laser head-based sunlight noise filtering method, a chip and a robot. Background technique [0002] The laser head is infrared data. After the spot is shot on the target, the camera is used to capture the position of the spot, and then the position of a single point is calculated by the method of triangulation. Due to the use of infrared rays, there will be a lot of noise in sunlight, especially under strong light. If there is noise in the image acquired by the robot, there are obviously no obstacles at the position inspected by the laser head of the robot, but there are laser spots there. If these noises are not dealt with, it will affect our map building and obstacle avoidance, and even the sweeper will keep avoiding obstacles and walking around. Contents of the invention [0003] In order to solve the above problems, the present invention provides a sunlight n...
