摘要
激光雷达主动发射激光,可高精度、高分辨率地获取入侵目标的距离、方位、速度及轮廓等信息,已在城市安防和工业安全等领域得到广泛应用。简要介绍了国内外主流安防激光雷达厂商及其产品技术指标。结合不同安防应用需求,从测距方案、扫描方式和光源选型三个方面重点讨论了不同技术体制下激光雷达的原理、特点及现状。最后对安防激光雷达的应用趋势及发展前景进行了总结与展望。为了满足消费级安防应用需求,安防激光雷达将进一步向低成本、高性能、系列化、小型化、固态化、芯片化及多源集成等方向发展。
A light detection and ranging(LiDAR)system can actively emit laser light to capture the distance,direction,speed,and contour of an intrusion target with high accuracy and high resolution,and thus it is widely used in the urban security,industrial fields,etc. This paper briefly introduces the mainstream manufacturers of security LiDAR at home and abroad as well as the technical indicators of their products. The principle,characteristics and current status of security LiDAR under different technological regimes are mainly discussed in terms of LiDAR ranging schemes,scanning methods and light source selection,combined with different security applications. The application trend and development future of security LiDAR are summarized and prospected in the end. Security LiDAR will develop toward low-cost,highperformance,serialization,miniaturization,solidification,chip,and multi-source integration.
