Sammanfattning
Embedded sound positioning software Kristian Björk (D06) and Kristian Björk (D06) Start: 2010-09-01 The surveillance intelligence in cameras is increasing, for the most part it is video applications. This thesis is a push forward for embedded audio intelligence. On the market today there are similar high end dedicated sound detection systems. To be able to use large networks of cameras to detect the position of sound is a difficult task and requires a lot of the camera. This thesis is to be a proof of concept. The goal of this master's thesis is to demonstrate that it is possible to construct a sound positioning system under simple circumstances. This task is both theoretical and practical. Investigate different ways to identify the sound and determine ways to improve the performance. All is to be implemented in an Axis network camera. Suggest improvements for audio in current Axis software. Evaluate future improvements and possibilities to the prototype. * Determine the possible precision of off position estimates * Suggest methods for sound identification * Implement a proof of concept on an Axis network camera * Cancellations of unwanted sound artifacts such as echo Advisor: Bengt Mandersson (EIT) Advisor: Per Vilhelmsson (Axis Communications AB)
