Problems solved by technology

[0004] In the actual teaching process, when the teacher writes and explains on the writing board, the students' attention is on the content written by the teacher, but part of the content being written or the content that has been written may be blocked by the teacher's hand, such as figure 1 As shown, the content written by the teacher in the first line is P(C)=0.01=1%, but when the teacher writes the content of the second line, the content of "0.01 = 1%" in the first line is manually Covered, need to wait until the teacher moves the hand, this part of the written content can be received by the students, thus affecting the students' attention in the learning process

Abstract

The invention discloses a video processing method and apparatus, a terminal device and a storage medium. The method comprises the steps of obtaining a writing image corresponding to a region where a touch display screen is located from video data of a video shot by a camera facing to the touch display screen; collecting a writing track generated on the touch display screen in the shooting processof the camera, and mapping a collection moment of the writing track to a time axis of the writing image; and based on the time axis and a relative position of the writing track in the touch display screen, adding the writing track to the writing image. The problem that writing contents are shielded by a hand of a user in a video teaching process is solved; and the video teaching efficiency and theattention of students in a learning process are improved.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to a video processing method, device, terminal equipment, and storage medium. Background technique [0002] As the web continues to grow, so do teaching aids. In the 21st century, with the continuous popularization of PCs and notebooks, online education has also continued to rise with the development of network technology. [0003] In the existing technology, the teacher's lecture process can be recorded into a multimedia file, which can help students to study, review and preview conveniently, and can also form resource sharing between teachers and schools to improve the teaching force of teachers. At the same time, remote video teaching can also be carried out to learners in different regions through the network. [0004] In the actual teaching process, when the teacher writes and explains on the writing board, the students' attention is on the content w...
