摘要
激光雷达具有体积小、质量轻、探测距离远、高分辨率、高精度、高密度、快速成像等优点,目前已经成为世界各国优先发展的新式雷达。尤其是激光三维成像雷达技术,在科学实验领域、民用领域、商用领域以及军事领域迫切需求的刺激下,各种先进激光三维成像雷达技术迅速发展起来了。详细描述了不同体制下的激光三维成像雷达的研究现状,分别以国内外最先进的激光三维成像雷达为例,分析其基本成像原理,归纳其性能,对比不同体制激光三维成像雷达的优势与缺陷,总结出激光三维成像雷达未来的发展趋势,最终展望其应用前景。
Light detection and ranging(Lidar)has the advantages of small size,light weight,high resolution,high precision,high density,fast imaging,etc.Currently,it has become a new type priority development radar technology in the world.Especially,laser three-dimensional(3D)imaging lidar,which has rapidly developed in the field of scientific experiments,civil,commercial and military applications.In this paper,the research status of laser 3D imaging lidar is described in detail under different systems.We take the most advanced laser 3D imaging lidar as examples in the worldwide.The basic imaging principle of each lidar technology is analyzed.Their parameter indexes and performance are induced clearly.The advantages and disadvantages of different laser 3D imaging lidar are compared,then the future development trend of laser 3D imaging lidar is summarized,and finally,the application prospects are expected.
