Embodiment 1

[0034] refer to figure 1 , this embodiment provides a remote practical teaching system based on augmented reality projection interaction, the system includes:

[0035] The teacher terminal 001 includes: a display module for displaying the actual operation process of the student terminal, an interactive module for the teacher to conduct interactive guidance, a first data collection module for collecting the teacher's interactive guidance process, and a remote data receiving and sending module The first network communication module, wherein the interaction module interacts based on the student-end practical operation process provided by the display module, and the teacher directly interacts in the displayed practical operation screen, and provides interactive guidance information at any position specified by the teacher ;

[0036] Specifically, the teacher's end is composed of a notebook computer, the display screen of which is a display module, the keyboard, mouse, and touchpa...

Embodiment 2

[0042] refer to figure 2 , the present embodiment provides a remote practical teaching method based on augmented reality projection interaction, the method includes the following steps:

[0043] The projection correction step S101 is to set up a projector and a camera in the student's practical environment at the student end, and calculate the relative positional relationship between the projected coordinate system and the camera coordinate system, specifically including the following sub-steps:

[0044] 1.1 Adjust the positions of the projector 301 and the camera 303 according to the actual operation environment of the students and fix them with the bracket 305, so that the projection area 311 and the video shooting area 313 basically overlap and cover the actual operation area 315. Finally, the projector 301, camera 303, The spatial relationship between 315 in the actual operation area is as follows image 3 shown;

[0045] 1.2 After using brackets and other equipment to fi...

Abstract

The invention discloses a remote practical operation teaching method and system based on augmented reality projection interaction. The method enables a teacher to remotely watch the practical operation process of a student online, and carries out the online guidance of the student in a mode of voice and graph interaction at any time, a student terminal projects the guiding information drawn in real time to a practical operation area of the student through a projector so that the student is enabled to visually observe the guiding content of augmented reality, the intention of the teacher can bemore accurately and efficiently understood, and the learning efficiency of remote practical operation teaching can be greatly enhanced. The invention provides a new tutoring mode for remote practicaloperation teaching, the system is simple in composition and easy to construct, teachers and students can operate visually and efficiently, and a solution is provided for remote practical operation teaching which is difficult to realize originally.

Description

technical field [0001] The invention relates to the technical field of digital teaching, in particular to a remote practical teaching method and system based on augmented reality projection interaction. Background technique [0002] With the development of the digital age and the influence of uncertain factors such as epidemic control, distance teaching has become one of the important teaching methods. Existing distance teaching is mostly carried out in the form of electronic courseware, video and live broadcast, and the teaching is basically carried out in the form of students as viewers. At present, this method of teaching can only be observed through flat-panel display equipment, which is difficult to combine with actual operation. It lacks intuitive operation guidance, and it is difficult to support practical teaching with many components and complicated operation processes. Practical courses are an indispensable and important form of education in vocational education...
