Aiming at the problem of multi-sensors data weighted fusion

a data fusion method based on optimal weight value is proposed. The allocation principle of optimal weight is confirmed through analyzing on influence of fusion weight on fusion precision. The optimal weight allocation principle of data weight fusion. The approximate measurement precision calculation model of sensor in the actual work condition is built through statistics and analysis on actual measurement data which can reflect actual measurement precision of sensor. Typical example is used to validate the proposed algorithm

and the result shows that the problem of data weighted fusion of multisensors can be solved well by the algorithm

and has theoretical meaning and practical value.
