Voice positioning method based on minimum circle coverage algorithm

The invention discloses a voice positioning method based on a minimum circle coverage algorithm, and the method comprises the steps: distributing a plurality of voice direction finding modules in a space, and calculating the direction angle of a voice relative to the voice according to the position of the voice; determining coordinates of intersection points between the voice direction finding modules according to a coordinate system set manually; and determining the circle center of all the discretely distributed intersection point coordinates by using a minimum circle coverage algorithm, namely the final voice positioning coordinates. According to the invention, the influence of the direction finding error of each voice positioning module on the final positioning result is minimized by using the minimum coverage dot set method. 本发明公开了一种基于最小圆覆盖算法的语音定位方法，包括：在空间中分布多个语音测向模块，根据语音的位置计算出语音相对于自身的方向角度；根据人为设定的坐标系，确定每个语音测向模块之间的交点坐标；利用最小圆覆盖算法确定离散分布的所有交点坐标的圆心，即为最后的语音定位坐标；本发明利用最小覆盖圆点集的方法将每个语音定位模块的测向误差对最终的定位结果的影响减到了最小。
