Research on group target acoustic-image localization and data fusion method

Aiming at the localization problem of group target spatial coordinates in the experiment task, the acoustic wave and optical characteristics of the target are analyzed, and the localization method and mathematical model based on the fusion of meteorology, acoustic wave and optical image data are established. The fusion localization method was verified by experimental testing. According to different periods of day and night, different low vegetation ground, different visibility and optical background conditions, the rapid localization of the group target can be realized even in the case of serious sound wave superposition and the spread of fire and smoke on the ground, and the localization accuracy is better than 5m.
