Modern distance teaching activities have occupied an important position in current education and teaching activities. This research mainly discusses the application of digital image processing technology in remote interactive art teaching systems. In order to avoid complicated calculation and a huge amount of calculation, reduce the difficulty of calculation, and improve the correction speed of distorted image and for qualitative recognition and correction of a large background and small target (or medium and small target) digital images (video is regarded as a special form of continuous image, method-like) that appear in a large number of remote teaching activities, this paper proposes a direct look-up method based on coordinate interpolation, that is, to establish the approximate correspondence between the image coordinate positions before and after the distortion and build a reference model for comparing the two image coordinates through experimental data. The system design includes overall design, functional module design, and database design. To realize the function of distance education, it must have characteristics different from ordinary networks and the most important thing is that its transmission bandwidth should be large. Because the distance education platform needs to be able to transmit the teaching text, hear the teacher’s voice, see the teacher’s teaching image content, and even see the carefully designed animation, the distance education system must have a very wide bandwidth. The database tables are designed using entity attribute diagrams and E-R diagrams. E-R diagram is also called entity-connection diagram, which provides a way to express entity types, attributes, and connections. It is used to describe the conceptual model of the real world. Remote online test management includes test content perform operations such as addition. The art teaching management system designed in the article will make teachers and students no longer be restricted by time and place and can inquire about students’ information, choose courses freely, inquire about grades, and understand the teaching plan anytime and anywhere. This research helps to promote the development of remote interactive technology.
