摘要: 激光雷达扫描全景测量技术在数字化时代测绘领域的应用有着非常重要的意义。本文以深圳市海域动态监视监测为例,综合利用基于船载、单兵/车载的移动测量系统和基于卫星、无人机的高分辨率遥感影像等数据获取手段,获得全覆盖、立体化、高精度、高时效性的海域资源基础数据。并讨论了在海域监视监测工作中使用车船载激光雷达全景测量结合多时相高分辨率影像叠加分析方法的便利性、有效性、精确性。它不仅能让测绘生产单位在较短的时间内准确、及时地获取数据,还可以减少外业测量工作和内业的后续处理时间,大幅度提高了勘测工作的效率,值得借鉴和推广。

Abstract: The application of LiDAR scanning panoramic surveying technology in the field of surveying and mapping in the digital age is of great significance. In this paper, dynamic Marine surveillance and monitoring in Shenzhen city is taken as an example, and data acquisition means such as ship-borne, man-mounted/vehicle-mounted mobile measurement system and high-resolution remote sensing image based on satellite and uav are comprehensively applied to obtain the Marine resource basic data with full coverage, three-dimensional, high precision and high timeliness. The convenience, effectiveness and accuracy of panoramic survey of vehicle-borne LiDAR combined with multi-temporal high-resolution image superposition analysis method in Marine surveillance and monitoring are discussed. It can not only enable surveying and mapping production units to acquire data accurately and timely in a relatively short time, but also can reduce the field survey work and the follow-up processing time of the industry, greatly improving the efficiency of survey work, which is worthy of reference and promotion.

Key words: vehicle borne LiDAR, panoramic surveying, mobile measuring system, sea area monitoring, high resolution image
