资源说明:Over time, sensors have morphed from simple analog and mechanical constructs to chip-based digital devices that connect to a machine to monitor the machine’s health as well as environmental conditions. Similarly, sensor fusion — multiple types of sensors working together to solve a problem — has combined the threads of many other technologies to create something very new and exciting.
The idea of using a computational device to sort out the data from multiple sensors and combine information to draw a conclusion has been around since at least the 1950s. But it was exceptionally difficult to do. Around 1960, several mathematicians developed sets of algorithms in an effort to have a machine draw a conclusion based on input from multiple sensors. These filters also removed meaningless data from noise or other sources. Of course, it wasn’t long before the military decided that this technology would be useful in their applications. Being able to process inputs from multiple sources and compare it with stored data would allow the military to better track and identify potential airborne targets and even compute the certainty of the results. With better computers and sensors, the technology was advancing, but there were still complex and expensive problems to solve.
【传感器融合技术的发展与应用】
随着科技的进步,传感器已经从早期的简单模拟和机械结构演变为集成在芯片上的数字设备,这些设备可以连接到机器上,不仅监测机器的运行状态,还能感知周围环境条件。传感器融合,即多种类型的传感器协同工作以解决特定问题的技术,融合了多个领域的创新,为现代科技带来了全新的可能性。
自20世纪50年代以来,利用计算设备整合来自多个传感器的数据并结合信息得出结论的概念就已经存在。然而,在当时,这一技术实施起来极其困难。大约在1960年,一些数学家开发了算法集,旨在使机器能够基于多个传感器的输入信息来做出判断。这些算法还能过滤掉由噪声或其他来源产生的无意义数据。不久之后,军事领域认识到这种技术在目标追踪和识别,甚至是结果可信度计算中的潜在价值。随着计算机和传感器技术的提升,该技术逐渐发展,尽管仍然面临复杂性和高昂成本的问题。
【微机电系统(MEMS)在传感器融合中的作用】
