摘要
数据处理软件是激光雷达系统的重要组成部分。根据车载测污激光雷达采集系统的特性与科研工作的需要设计了车载测污激光雷达数据处理软件。该软件集成了测量物的数据处理与显示功能;能够实时检测到激光雷达的回波信号,并自动进行处理;解决了多种测量物时间、空间分布实时显示的问题。在软件设计过程中,采用了双缓冲技术消除了闪烁现象;利用API函数实现了实时处理功能;在等值线的绘制中使用了不规则三角网对数据进行建模。经过测试,该软件能较好地完成车载测污激光雷达的数据处理工作。
Data processing software is one of important parts in lidar system.A data processing software is designed for needs of scientific research,which is used in a monitoring pollutants mobile lidar and based on feature of the lidar data acquisition system.The software comprises both functions of data processing and real-timedisplay of pollutants concentration,and can detect lidar real-time echo and then automatically deal with it.So the software overcome the difficults in real-time temporal and spatial distribution display of multi-pollutant.The flicker phenomena is avoided by using the double buffering technique,and real-time display is achieved by using API function.In plot of contour line,triangulated lrregular network to model data was adopted.At last,the software was demonstrated feasible for satisfing the requirements of the lidar data processing by testing.
