近20年来，由于超大规模集成（VLSI）和超高速集成电路（VHSIC）、高精度数控机床、计算机辅助设计和制造，以及其他设计和生产的改进，传感器性能的大大提高，各种面向复杂应用背景的军用或民用多传感器信息系统也随之大量涌现。在多传感器系统中，信息表现形式的多样性、信息容量以及信息的处理速度等要求，都大大超过了人脑的信息综合能力，因此出现了信息融合技术。-Over the past 20 years, due to ultra-large-scale integration (VLSI) and ultra-high-speed integrated circuits (VHSIC), high-precision CNC machine tools, computer-aided design and manufacturing, as well as other design and production improvements, greatly improve sensor performance, various surface complex applications to the military or civilian background of multi-sensor information systems have also emerged in large numbers. In multi-sensor system, the performance of the diversity of information, information capacity and information processing speed, etc., are much higher than the synthesis of the information the human brain capacity, so the information fusion technology.
