New classroom teaching model based on machine vision technology

Abstract

The invention discloses a new classroom teaching model based on the machine vision technology. The new classroom teaching model solves the problems existing in traditional measurement technology teaching. Hardware comprises a CCD image sensor of a USB interface, a sphere integration light source, a computer, a standard part with the diameter phi of 40.00 mm and a workpiece to be measured. Software is used for workpiece dimension measurement independent learning software based on the machine vision technology. According to the technical scheme of a system, a program is initialized, and a graphical user interface pops up; a video is started, and communication between the computer and a camera is achieved; calibration is performed, and the unit conversion relation is obtained; judgment is made, and students learn through independent operation; the video is stopped, communication between the computer and the camera is stopped; scores are queried, analysis is performed in time, and thus targeted teaching can be achieved and instructions can be given in good time. The system not only can meet the requirements of a traditional classroom but also can motivate the students, repetitive work of teachers is reduced, classroom efficiency is improved, the information-based teaching development progress of vocational schools is promoted, and the application and popularization prospects are broad.

Description

technical field [0001] This patent involves the promotion of machine vision technology research results in the manufacturing and processing industry to classroom teaching in vocational schools, especially a new classroom teaching model based on machine vision technology. Background technique [0002] "Measurement Technology" is an important teaching unit in the main course "Extreme Fit and Technical Measurement" of CNC major. The measurement of the geometric parameters of the parts mainly includes length, angle, surface roughness and shape error. Commonly used measuring tools mainly include vernier calipers, micrometers, inner diameter dial indicators and universal angle rulers. Through the study and practical training of this unit, students should be proficient in the use of basic measuring tools such as vernier calipers, micrometers, inner diameter dial indicators and universal angle rulers.

AI Technical Summary

Problems solved by technology

In the traditional teaching method, students often make mistakes in repeated practice, resulting in the inability to correctly grasp the use method; at the same time, although the teacher has to do a lot of repetitive work for the whole class, he still cannot do it for every student. examination test
