An Interactive Multiplayer Mobile Application using Feature Detection and Matching for Tourism Promotion
Waraporn Viyanon · 2019
The idea of developing an interactive multi-player mobile application for tourism promotion using image matching on the Android platform was initiated from the Thai government's policy promoting tourism in order to have a significant impact on the revenues of Thai tourism industry. This application requires a user to be in a real place to complete missions that he or she has selected. The application navigates the user to the selected place. While playing, the user must do missions by taking photos of an object specified in the gallery database in a period of time. The taken photo will be compared with images in the gallery using Oriented FAST and Rotated BRIEF (ORB), the feature detection and matching. Each set of images tested with SSD, SAD, and NCC algorithms with different thresholds in order to find a suitable value that gives good results. In order to make the application more engaging, the application was designed to use/play with multiple users. The experimental results show that the application can detect user's position and lead the user to the target place correctly using GPS technology and can compare images accurately in case of the taken image and the images in the gallery have the same angle or small angle (less than 30 degree) and have little difference in light intensity. The evaluation of overall user satisfaction from thirty testers is at a good level.
