29 May 2014 Low-cost localization system of impulsive sounds for urban environments
Author Affiliations +
A low-cost acoustic localization system is presented, in which a video camera is directed towards the source of impulsive sounds such as gunshots. An analog filter is implemented at the first stage, in order to reduce the range of frequencies to analyze, hence narrowing and improving the localization of gunshots. The system is design for the integration of open source consumer electronics and processing devices, which makes large-scale deployment possible even in developing countries. Furthermore, results are also obtained with a prototype that shows a high percentage of successes.
