MULTI-SENSOR DATA FUSION METHOD FOR INTEGRATED SURVEYING AND MAPPING OF INTERTIDAL ZONE

摘要

The present invention provides a multi-sensor data fusion method for integrated surveying and mapping of intertidal zone. A carrier vehicle is comprised; the carrier vehicle is provided with sensors; the sensors comprise a satellite positioning system, an inertial navigation system, a laser scanner, a single beam sounder, and a towing sounder. In the method, a precise industrial measurement system is adopted to calibrate the phase center and the axis system of each sensor; the single beam sounder is adopted to acquire data in a shallow water area, the towing sounder is adopted to acquire data in a shoal area, the laser scanner is adopted to acquire data on land; data coordinates acquired in the laser scanner coordinate system, the single beam coordinate system and the towing sounder coordinate system are converted to be in a WGS84 coordinate system. The method solves the problem of incomplete topographic surveying and mapping of intertidal zone, and can complete topographic surveying and mapping of intertidal zone quickly and accurately.
