Integration and Optimization of Multimedia Technology in Art and Painting Education under Big Data

With the continuous changes in art and painting teaching problems, the commonly used methods can no longer solve the problem very well. At this time, we use multimedia technology to study them in the context of big data. The experiments show that: (1) Multimedia technology can be well integrated into the teaching of art and painting; the rapport rate between them reached 92%. The problem that the system would sometimes become unstable was solved through the optimization algorithm, and finally, the overall score of the model was obtained through the evaluation algorithm to be floating between 88–94 points. (2) According to the data of the figures and tables, it can be concluded that due to the integration of multimedia technology into the teaching of art and painting, my country is paying more and more attention to it anyway, and the amount invested is also increasing, which has changed from the original 2.5 billion to 4 billion yuan. In the future, the training of art and painting teaching talents will be 123 million yuan in 2020–222 million yuan in 2024, and the proportion of my country’s art and painting transactions will basically account for 50%. Finally, the teaching of art and painting in our country will become better and better.
