Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0045] Make the server side and establish a standard answer database system. The server side mainly includes two contents, one is the real-time operation of the image processing algorithm, and the other is the standard answer database, such as figure 1 shown.

[0046] Firstly, image processing related algorithms are implemented on the server side. One of the most important considerations for setting image processing algorithms on the server side is to reduce the computing pressure on the mobile terminal and improve the real-time performance of the system.

[0047] Secondly, establish a standard answer database on the server side. This database mainly contains a large number of mechanical drawing homework exercises and corresponding answers. The database has many different tables, each table correspon...

Abstract

The invention discloses a drawing-type-work reviewing method based on an augmented reality technology. The method includes the following steps: using a mobile terminal as a client to obtain image frames and sending data to a server side and receiving data from the server side and displaying the data; receiving video frame data transmitted by the client and processing images through an image processing related algorithm; sending standard answer view models and reference grades obtained through calculation to the client; the client rendering the models to the video frames through an OpenGL after receiving the data sent by the server side and displaying the reference grades through superposition of layers so as to achieve a virtual-real fusion confusion effect. The drawing-type-work reviewing method based on the augmented reality technology assigns a drawing work reviewing task to computer vision which is combined with the augmented reality technology and transplants functions to the mobile terminal for realization so that great convenience and fun are brought to reviewing teachers.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to a method for reviewing drawing-type operations based on augmented reality technology. Background technique [0002] According to foreign media reports, the market research company Forrester has predicted the top ten development trends of the mobile industry in 2013, which can be summed up in six words: mobile changes everything. Mobile phones are becoming more and more powerful and are gradually replacing cameras, cash payments, maps, remote control devices, handheld game consoles, boarding passes, tickets, cash registers, calculators and notepads. The ubiquitous mobile phone has become an indispensable product for people all over the world: 1.6 billion mobile phones were shipped worldwide last year, and there will be 1.4 billion smartphone users worldwide by the end of this year. It is not difficult to see from these data that mobile terminals will become an indispen...
