Abstract

The invention discloses an image recording system applicable to various teaching environments. The system is composed of two or more mobile shooting devices for shooting a teaching process, a reference module for establishing a reference coordinate system by using a lower left corner of an image shot by a reference shooting device as an original point, a conversion module for carrying out coordinate conversion on an image shot by another mobile shooting device to the reference coordinate system, an adjusting module for carrying out radial distortion adjustment on the image after coordinate conversion, and a splicing module for capturing features points of the image after distortion adjustment and carrying out image splicing to enable same feature points in the images shot by different mobile shooting devices to be overlapped. The invention provides an image recording system for various teaching environments; even if the teaching environments are different, the captured images are processed and debugging of the mobile devices is not needed, so that the whole teaching process is recorded without starting part missed.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an image recording system suitable for various teaching environments. Background technique [0002] Teaching video class is to record the entire classroom teaching process through video cameras and other video equipment, objectively record the teacher's teaching process, the student's learning process and the teaching scene of teacher-student interaction, and truly reflect the audio and video digital files of the classroom teaching effect. Because the teaching video course can objectively reflect the whole process of classroom teaching, including the teacher's teaching philosophy, teaching ability, teaching content, teaching resources used, teacher's organization of the teaching process, bilateral interaction between teachers and students, and the resulting teaching experience. Therefore, it is playing an increasingly important role in promoting excellent classroom teaching exp...
