Description: 基于互相关函数，采用求和广义互相关函数(summed-GCC)法用于机器人系统平台。由于采用不同的映射函数(mapping functions)，GCC法在该平台下，只需三个麦克风即可进行三维定位，突破了基于TDOA法进行三维声源定位最少需4个麦克风的限制-Based on cross-correlation function, using generalized cross-correlation function sum (summed-GCC) method for the robot system platform. Because of using different mapping function (mapping functions), GCC method in the platform, the only three to three-dimensional microphone positioning, a breakthrough TDOA method based on three-dimensional sound localization will take at least four microphone restrictions

Description: 结合马尔可夫过程，提出一种概率论的声源定位算法，并给出了基于DSP的机器人实现。其中声源定位部分采用三个麦克风呈三角形放置，为减小由于噪声等引起的TDOA估计误差，采用马尔可夫过程计算时延，这样计算的时延会更可靠。该方案中的声源定位也属于一维定位，即只需知道声源的方向角-Combination of Markov process, a probability theory of sound source location algorithm, and give the robot based on the DSP implementation. Sound Source Localization in part one of the three microphones were used to place the triangle, in order to reduce the noise caused because of the TDOA estimation error, calculated using Markov process time delay, such delay will be calculated more reliable. The program of the sound source location is also a one-dimensional positioning, that is, only need to know the direction of the sound source angle

Description: It is a graphical user interface for avoustic source localisation. It uses an
imote2 wireless sensor with four microphone to determine the acoustic source
coordinate with the TDOA methode. The link between the host pc and the imote is
established using a TCP/IP communication. Embedded linux is installed on the
Imote2. The analog to digital converter found on the ITS400 card board is used
to sample the sound signal, four microphone simultaneously.
