Research on the Digital Method of Teaching Resources Based on Raspberry Pi

Abstract

At present, online teaching resources are mainly produced by some software like Rain classroom, or recording video in professional rooms. Both methods have their own advantages and disadvantages, and put into school level, there are still a large part of schools can not provide students with sufficient and excellent online teaching resources. In order to realize an easier way to digitize teaching resources, this paper uses Raspberry Pi as the core processor, camera module and Python-OpenCV library as the basis, and combines Yolov4-tiny algorithm to realize the digitization of teaching resources, which provides a more economical and convenient way to utilize teaching resources. The digital method could promote the circulation of teaching resources and raise the frequency of information exchange inside and outside the school.
