| 摘 要： | 针对激光雷达在物性信息探测方面的缺陷，提出了一种新型多光谱激光雷达用于地物探测，兼具三维空间探测能力和物性探测能力。随着探测波长增加，多光谱激光雷达数据采集与处理对整个系统的运行至关重要。根据多光谱激光雷达系统结构原理，基于图形化编程语言Lab-VIEW，进行数据采集与处理系统单元及整体设计，实现系统功能需求。通过实验运行，数据采集与处理系统的运行良好，同时多通道回波信号的采集也进一步验证了多光谱激光雷达的物性探测能力。

| Abstract: | In order to improve the ability of detecting properties of objects, a multi-spectral lidar which can acquire both three-dimensional spatial information and multi-spectral information is proposed by Wuhan University. With the increase of detection wavelengths, data acquisition and processing become the crucial point in multi-spectral lidar system. According to the discussion about block diagram of multi-spectral lidar, a design proposal based on the LabVIEW development platform is presented to achieve data acquisition and processing. Through experiment, the system can operate well. The backscatter sig- nals further verifies the detection ability of multi-spectral lidar. |
