Implementación de un prototipo de dispositivo electrónico que mediante el procesamiento de imágenes con visión artificial muestre la información de circuitos turísticos del centro histórico de la ciudad de Riobamba.

Abstract

The present graduation work describes the development of a portable device that allows to detect the different pictograms of the tourist signs of the historic center of the city of Riobamba using artificial vision, and in turn applying the SIFT and FLANN algorithm which, thanks to the detection of the characteristic points of each pictogram or image of the signs, can detect tourist places, it also has a guiding stage by means of generating routes of each tourist place depending on the pictogram detected, this information is transmitted through a map on a screen installed in the prototype for a better interaction and the efficiency of data transmission to the final user. Altogether, a user-friendly application was elaborated where tourists can take the image, choose the place and be guided by this device. The tourist places of the historical center of the city of Riobamba can be churches, parks, squares, markets etc. therefore, in addition to the guiding stage, it has an information screen of the tourist place with basic and important information of the place. It should be noted that the vision system has two parts for its operation, the image detection stage covered by the SIFT-FLANN algorithm previously mentioned, and a character detection algorithm which works to identify the written signs or those containing words. The prototype is intended for the tourist field as well as the experimental educational area, for that reason the development of the prototype applied the deductive and experimental methods both in the information gathering stage for the development of the device, and in the selection, design and construction stage. Finally, it must be remarked the use of hardware and free software oriented to the development of research works.
