Ancient cultural relic scene fast rendering method based on augmented reality technology

Abstract

The invention discloses an ancient cultural relic scene fast rendering method based on the augmented reality technology. The method specifically comprises the steps that 1), a landmark is prepared, and data collection is conducted on a cultural relic; 2) the three-dimensional landmark is tracked through a camera, recognition and analysis of the three-dimensional landmark are conducted, three-dimensional landmark area partition is conducted, an environment chartlet is built, and the position and intensity of a light source are obtained in the environment charlet; 3) a virtual illumination model with real-time light rendered is built; 4) a virtual object model is built for the ancient cultural relic, and a three-dimensional model of the ancient cultural relic is obtained; 5) hidden surface elimination is conducted on the built virtual object model of the ancient cultural relic; 6) shadows are added for the three-dimensional model of the ancient cultural relic, and the shadows are softened to be soft shadows; 7) an virtual illumination and virtual ancient cultural relic real-time interactive system is obtained. The ancient cultural relic scene fast rendering method displays the three-dimensional model of the ancient cultural relic to a real scene through the augmented reality and fast rendering technology, and virtual-real interaction is conducted through a display device.

Description

technical field [0001] The invention belongs to the technical field of virtual reality, and in particular relates to a rapid rendering method of ancient cultural relic scenes based on augmented reality technology. Background technique [0002] Ancient cultural relics are precious property left to us by our ancestors and an important way for us to explore ancient culture. With the passage of time, many ancient cultural relics are facing inevitable reverse changes, loss, fading and decay, which we cannot prevent. Today, with the emphasis on the inheritance of material culture and history, the protection and development of intangible cultural heritage has received unprecedented attention. At present, our appreciation of cultural relics is only at the stage of "only being able to see it from a distance", and the development of augmented reality technology provides a new and important way for this. The research and application of augmented reality technology can help rescue, pro...

Problems solved by technology

[0004] At present, in the protection of cultural relics, the application of augmented reality technology is still rarely reported. The domestic development is mainly the Augmented Reality on-site digital reconstruction system of the Old Summer Palace Western Scenic Spot of Beijing Institute of Technology; while the foreign development is mainly IntraCom with the support of the European Union. Developed an electronic tour guide system for historical sites that uses augmented reality technology to restore on-site restoration of ancient Greek ruins; but neither of them has performed real-time rendering of cultural relics, that is, there is no "interaction" between observers and cultural relics
