Abstract:
1. A method for estimating a position of N sound-emitting transducers, where N≧2, where the method comprises the following steps: a) determining individual distances d b) based on said individual distances d c) executing an error identification and correction when an overall stress value provided by said MDS algorithm exceeds a given maximum value, said executing step including the steps of subdividing said distance matrix M into sub-matrixes, thereby providing stress values for each of these sub-matrixes, and determining that the or those sub-matrixes resulting in stress values outside a given tolerance region comprise at least one pair of transducers, the determined distance between which is erroneous; d) providing the co-ordinates of the pair of said at least one pair of transducers to an error detection algorithm thereby providing an error matrix; e) providing said error matrix and said overall stress value to an optimization algorithm that optimizes said distance matrix; f) based on the optimized distance matrix, estimating the relative co-ordinates (x g) comparing said updated stress value with said given tolerance region of stress values and repeating steps (c) through (f) until said updated stress value is outside said tolerance; and h) when the updated stress value is outside said tolerance region, providing the relative co-ordinates that are based on the optimized distance matrix as the result of the preceding steps.
