摘　　要：船载多传感器综合测量系统集成了三维激光扫描仪、多波束测深仪、GNSS、IMU、传感器稳定平台等传感器,采用非接触式的测量方式同步获取水上水下地形,在海岸带和海岛礁测绘中有巨大的应用价值。由于测量瞬时数据量大,系统点云实时显示是采集软件的重要组成部分。在有效地控制时间同步的前提下,优化数据融合效率,采用VTK(visualization toolkit)技术实现了海岸线上下一体化点云实时显示,有效地提高了系统的信息挖掘能力和现场决策支持能力,最终实现了水上水下一体化测量。The Shipborne Multi-Sensor Measurement System integrates 3D Laser Scanner, Multi-Beam Swath Bathymeter, GNSS, IMU, Sensor Stable Platform.It can synchronously obtain surface and underwater topography by non-contact measurement, which has great application values in surveying and mapping for coastal zones, islands and reefs.Because of the massive measurement instantaneous data, the point cloud real-time display of the system is an important part of the acquisition software. In this article, on the premise of the effective time synchronization control, the point cloud real-time display of surface and underwater integration has been realized by optimizing the efficiency of data aggregation and using VTK technology. In conclusion, the technology has effectively improved the abilities of information mining and scene decision support and realized surface and underwater integration measurements.
