摘要
Method for calculating a position and possible mapping of a space-related variable by means of acoustic signals, comprising the following steps: providing at least three position emitters (A, B, C, D) with known relative position at a three-dimensional measuring space and at least one acoustic receiver (R) located at a not known distance (D1, D2, D3, D4) from each of said position emitters (A, B, C, D); making each position emitter (A, B, C, D) emit a position acoustic signal (X1, X2, X3, X4); acquiring by means of the acoustic receiver (R) a received acoustic signal (J) comprising contributions associated with the individual position acoustic signals (X1, X2, X3, X4); obtaining a position identification signal (H1, H2, H3, H4) for every position acoustic signal (X1, X2, X3, X4); obtaining, from the position identification signals (H1, H2, H3, H4), the time of flight (T1, T2, T3, T4); calculating the distances (D1, D2, D3, D4) starting from the times of flight (T1, T2, T3, T4); calculating the position (P) of the acoustic receiver (R) in the three- dimensional measuring space starting from said distances (D1, D2, D3, D4).
