基于小波变换的激光测距奇异值处理

Singular Value Processing in Laser Ranging Based on Wavelet Transform

随着科学技术的不断发展,人们对测量技术的要求越来越高,激光传感器利用被测物体反射激光,经信号处理器后将光信号转换为电信号,从而准确测得物体的实际距离。但是由于激光自身反射的不足,导致接受到的数据不可避免地存在奇异值。本文提出利用小波变换的原理,将其应用于激光测距中处理测量信号中的奇异数据,并通过仿真验证了这种方法的可行性。

With the development of science and technology, people put forward more and more demands on the measuring technology. Through reflecting laser by object and converting light signal to electrical signal by signal processor, laser sensor thereby measured the actual distance of object accurately. But the received data existed singular value inevitably because of the laser reflection’s shortcomings. In this paper, the principle of wavelet transform was applied to the treatment of singular value in laser ranging, and the feasibility of this method was verified by simulation.
