Abstract

The invention discloses a projection image processing method based on a contour detection algorithm, a server, a teaching system and a medium. The method comprise: an image acquisition device acquiring a first image and sending the first image to the server for processing, and the server responding to the received first image and then extracting first contour data of the first image; detecting second contour data in the projection image corresponding to the first contour data according to a coordinate conversion relationship between the first image and the projection image; therefore, the server performing operation on the first contour data and the second contour data, and transmitting the operated projection image to the shunt projection equipment in real time. Based on this, through extracting the first contour data of the real image, the first contour data and the second contour data at the corresponding position of the projection image are matched and superposed to enhance the definition of the projection image, so that students can clearly see the situation and courseware content of a teaching site, and the teaching quality of teachers and the learning effect of the studentsare ensured.

Description

technical field

[0001] The present invention generally relates to the field of teaching technology, and specifically relates to a method for processing projected images, a server, a teaching system and a medium. Background technique

[0002] With the rapid development of network technology and the wide application of multimedia, network teaching based on online video has changed the traditional classroom teaching mode, freed teachers and students from time and geographical constraints, and expanded the scope of classroom teaching. In addition, compared with traditional classroom teaching, online teaching also has the advantages that the number of students is not limited by the size of the classroom, and the teaching content can be updated in a timely and low-cost manner.

[0003] In the process of online teaching, the teacher will show the situation of the teaching site and the content of the courseware to the students through the projection screen. However, the low definit...
