The invention relates to the technical field of unmanned aerial vehicle search and rescue, and discloses an unmanned aerial vehicle platform-based sound source positioning system, which comprises an aircraft, a closed bin, a main image acquisition module, a noise reduction module, an anti-inertia damping release module, a sound acquisition module, a collection control module and a micro image acquisition module, the anti-inertia damping release module is arranged in the closed bin and is used for adjusting the distance between the main image acquisition module and the sound acquisition module and improving the sound acquisition precision of the dense forest area; the sound acquisition module and the main image acquisition module are separated and parallel by using the anti-inertia damping release module, the positioning mode of high-position acquisition and low-position sound acquisition is realized by combining time delay positioning, the influence of dense forest on sound energy reduction is reduced by using the crown-attaching flight of the sound acquisition mechanism, and the method is applied to search and rescue in mountainous regions and dense forests, such as poor sound acquisition quality and low noise. And the search and rescue precision and the search and rescue quality are improved in a low-position flight image acquisition area which is too small.
本发明涉及无人机搜救技术领域,本发明公开了一种基于无人机平台的声源定位系统,包括飞行器、封闭仓,还包括主图像采集模块、降噪模块、抗惯性阻尼释放模块、声音采集模块、收集控制模块、微图像采集模块,所述抗惯性阻尼释放模块设置在所述封闭仓的内部,用于调节所述主图像采集模块与所述声音采集模块的间距,提高密林区声音采集精度;利用抗惯性阻尼释放模块将声音采集模块与主图像采集模块分离并行,结合时延定位,实现高位采集,低位采声的定位方式,利用采声机构的贴冠飞行降低密林对声能降低的影响,应用于山地、密林搜救时的声音采集质量差,低位飞行图像采集区域过小的区域提高搜救精度与搜救质量。
