Photogrammetry and Augmented Reality to Promote the Religious Cultural Heritage of San Pedro Cathedral in Guayaquil, Ecuador

Abstract

This innovative proposal combines the use of the biggest reality and photogrammetry for modeling structures in digital format. It addresses two themes the use of technologies for the restoration of heritage structures in the event of a fortuitous event and the use of a technological tool that allows the dissemination of the religious cultural heritage of the Cathedral of San Pedro in Guayaquil, Ecuador to national and foreign tourists, the interest in knowing a little more about the history of culture and art is encouraged when effective conservation strategies are involved and even more by incorporating the use of technology in smart devices. This allows easy quick access with proper visualization, the use of photogrammetry technique is adopted in several museums around the world and allow tourists to learn about a specific topic in a didactic and interactive way. Another technique is the increasing reality technique, this technique incorporates data in virtual form links on the web audio video, video text or other multimedia through markers to objects serving as a tool that encourages learning more about different topics. The one chosen in this work is the religious cultural heritage. The interface developed in Unity, and the use of the Vuforia development kit, through the mobile application “My Cathedral”, allows users to access relevant historical information, visualizing the photogrammetric images in increasing reality, precisely on the most representative objects of the cathedral of San Pedro in Guayaquil.
