As of now, the use of PC innovation has understood the change of individuals’ creation and way of life, and furthermore advanced the improvement of computerized media workmanship. The current media digitization and artistic strength is more and more powerful than the previous application. Involving its high level techniques and advancements for data show, this paper proposed to utilize AR innovation to coordinate and methodicallly develop galleries under the craft of computerized media workmanship, which is useful to dissect and tackle objective issues, for example, biological lopsidedness and single framework capability in advanced media workmanship. Based on the principles and laws of augmented reality technology, the construction and optimization of the museum guide system under digital media art is carried out. In the system evaluation experiment, the classical image is first used as the target image, and the image of 120 × 120 pixels at the center of the image is used as the image target. The target image is rotated in the range of 0 degrees to 180 degrees, and the feature points are coincident at different angles. In the experiments, RERIEF, ORB and BRIEF were compared. Among them, the ORB algorithm must calculate the orientation of the feature points before constructing the feature descriptor, so the ORB descriptor contains the directional features of the feature points and has rotation invariance. Its principal orientation is defined as the orientation of the feature points in the circular neighborhood, but the overall performance is still slightly worse than the RERIEF feature description. Therefore, the application prospect of AR technology in digital media design is very important.
