Abstract

In virtual reality, traditional roaming methods are limited to a single ground roaming. In order to enrich tourists' roaming experience, this paper proposes an aerial photography path planning method based on areas of interest. First, by obtaining the characteristic information of the landmark, including the outline of the landmark and the middle area of the top surface of the landmark, the corresponding saliency value of the landmark surface is calculated. Then, a landmark-centered viewpoint quality field is constructed to guide local virtual camera motion. In this process, the saliency value is combined with the center composition and the rule of thirds composition in photography techniques to calculate the viewpoint quality score. Finally, a diagonal composition method was adopted to provide an excellent visual experience for flying between landmarks. Experiments show that the aerial photography path obtained by this method allows users to appreciate the beautiful scenery of the city from an aerial perspective in a short period of time, and has strong practicability and applicability.
