本文基于C++编程语言设计了距离选通激光成像雷达三维点云实时成像软件。软件以距离选通激光成像雷达成像原理为基础,实现了激光器和延时器的时序控制、点云数据的高速处理、滤波去噪以及三维图像的实时显示。基于自研硬件设备,利用本文设计的软件,对距离为700 m的建筑进行了三维成像实验。实验过程中,该软件能够实现多参数实时控制及目标三维图像的实时显示,三维图像距离分辨率达到0.157 m,实验结果表明,该软件具有精度高、速度快、可操作性强等优点,在远距离探测以及实时三维成像等应用中具有广阔前景。

Based on the C++programming language,this paper designs a software of the range-gated imaging lidar to display the 3D point cloud in real-time.The software is based on the imaging principle of range-gated lidar,realizes the7 timing control of laser and time delay controller,high-speed processing of point cloud data,filtering and denoising,and display the 3D images in real-time.Based on the self-developed range-gated lidar and the software designed in this paper,an imaging experiment was carried out on a building with a distance of 700 m.During the experiment,the software can control the multi-parameter of the range-gated lidar and display the 3D image of the target in real-time.The distance resolution of the 3D image reaches 0.157 m.The experimental results show that the software has the advantages of high accuracy,fast speed,and strong operability.It has a broad prospect in applications such as long-distance detection and real-time three-dimensional imaging.
