Compared with the prior art, the invention has the following advantages: traditional animation art teaching is generally a mode combining theoretical teaching and actual operation, and the actual operation is generally a mode requiring students to complete homework in an studio. With the development of the technology, many animation art teaching courses cancel the studio drawing mode and replace the studio drawing mode with the computer electronic drawing mode to finish the operation. Although the current computer is completely integrated with the animation art teaching process, due to the particularity of the animation art teaching, many teachers hope to visit the art exhibition and guide students to find spiritual creative works, and meanwhile, many students hope to finish painting on seats of coffee shops, bookstores, libraries and even roadside at any time and any place, so that the spiritual feelings of creators can be furthest prevented from being lost. Teachers and students also want to be able to show on all course participants' terminals within the class directly after the drawing is completed. The current mobile terminal can provide a technology for creating at any time and any place, but the works can only be stored locally, cannot be uploaded to the cloud, and cannot be displayed on the terminals of all course participants in a class in real time. The invention provides a method for uploading the drawing of a student, and the invention provides an image data transmission method and a remote teaching system for animation art teaching in a targeted manner.
