Abstract

为了改善激光测距数据处理中信号提取困难以及自动化程度还不高的现状,考虑激光测距数据的特征,结合二值图像处理和分析的技术提出一种新的提取测距信号的方法。先将原始数据映射为一幅二值图像,根据激光测距数据密度分布特点作第一次粗略的去噪,再根据信号形状特征作一次细去噪,将去噪后的图像矩阵逆映射回来。实验结果显示用于各种激光测距中的自动数据处理有很好的效果,可替代人工选点的激光测距数据提取方式。

Other Abstract

In order to improve the situation of laser ranging signal extraction problem and degree of automation, the feature of laser ranging data are listed, considering these feature and combination of binary image analysis a new method extracting the signal from the laser ranging data that contain a lot of noise is proposed. Before removing the noise the original data should be mapped into a binary image matrix in the method. According to the density of signal is higher than noise, the first step is done to remove the noise in the image matrix. The second step is done to remove the noise based on the feature that the signal is similar to a line in the image. The result of the image which has been processed should be inversely mapped back. The experimental results show that it is a potential method which can extract signal automatically and replace artificial methods.
