红外与声波协同生命探测平台研发

基于单一类型信息源的生命探测技术因自身缺陷无法完全满足震后救援的需要。该文在介绍音频、视频和雷达生命探测技术工作原理的基础上，分析它们各自具有的优势和存在的问题，给出异类多传感器协同探测的优势与现状，设计红外与声波协同生命探测平台，给出平台的结构模型、传感器的选择策略以及相应的性能指标。主要实现红外图像与声波信息的同步采集、分析与处理，兼具音频生命探测和视频生命探测的功能，弥补单一传感器生命探测仪的不足，能得到更全面、更准确的生命体及救援现场信息，更适用于震后复杂的救援环境。

Design life detection synergy platform with infrared and acoustic wave

Life detection technology based on a single type of information sources can＇t completely meet the needs of the earthquake relief, because they can＇t make up for their own defects. This paper introduces the existing life detection techniques including acoustic wave life detection, optical life detection and radar life detection. The advantages and existing problems of the three life detection techniques are also analyzed. The advantages and present situation of multi-sensor detection synergy technique are given. The life detection synergy platform is designed with infrared and acoustic wave in this paper. And the platform structure model, multi-sensor selection strategy and performance index are introduced too. Finally, the development direction of life detection technique based on multi-sensor synergy is forecasted. This platform can synchronously collect, analyze and process infrared image and acoustic wave, has the functions of audio life detection and video detection function, makes up for the deficiency of the single sensor life detector. It can get more comprehensive and more accurate information about the scene of rescue and living organisms, and it is more suitable for complex quake rescue environment.
