Abstract

The invention relates to an automatic blackboard wiping device and belongs to the field of image recognition and automation. The automatic blackboard wiping device uses a camera to identify a wiping area and controls a blackboard eraser to identify area dust by a microcomputer combining an ingenious mechanical structure. The traditional way of wiping is time-consuming and harmful to bodies of wiping people; and existing automatic wiping devices in the market are mostly for all-area wiping, and the existing automatic wiping devices have no selectivity, low efficiency, long operation time and waste energy in the wiping process. The automatic blackboard wiping device comprises an intelligent image recognition module, a microcomputer control module and a mechanical motion structure module, thewhole situation of a blackboard is captured by the camera, and the information is fed back to a microcomputer, the microcomputer can intelligently recognize the wiping area through binarization processing of the picture and then controls a motor to rotates to control the blackboard eraser to wipe the blackboard purposefully. The main purpose of the automatic blackboard wiping device is to replacethe traditional blackboard eraser wiping method and realize efficient and intelligent automatic wiping of the blackboard.

Description

Technical field [0001] The invention relates to a blackboard wiping device, in particular to realize automatic, efficient and purposeful wiping of a blackboard by using a mechanical structure and image recognition, and belongs to the field of image recognition and automation. Background technique [0002] Dust is a very harmful substance to the human body. It mainly damages the respiratory system of the human body. It has great damage to the lungs, upper respiratory tract, eyes, skin and ears of the human body. Long-term inhalation of high concentrations of dust can cause coughing and difficulty breathing. Symptoms such as hemoptysis and hemoptysis can even cause serious damage to the human lungs. [0003] In the daily teaching process of teachers, blackboard erasers are commonly used teaching aids. Teachers often need to write a lot of blackboard writing on the blackboard, and the teacher or student manually erase the blackboard, which brings great inconvenience to the teacher’s ...
