| 摘 要： | 针对基于小波理论的多光谱激光雷达消噪信号,从能量、图形、统计多角度出发,提出了由信噪比、平滑度等6项指标组成的小波消噪效果评价体系。实验证明,该体系可以为多光谱激光雷达消噪信号提供更加全面客观的效果评价,为不同信号噪声去除方法的选择提供更加可靠的依据,同时也有利于对不同算法进行有针对性的改进。

| Abstract: | Based on the wavelet de-noising signal of multi-spectral Lidar,the wavelet de-noising effect evaluationsystem is established from the aspects of energy,graphics and statistic.In the system six indicators are proposed,such as signal-noise ratio ( SNR) and Signal smoothness etc. Experimental results show that the system canprovide a more comprehensive and objective evaluation which will provide a more reliable basis for the selectionof different noise reduction methods.Meanwhile,it will improve the algorithms. |
