摘要
针对在水下地形数据采集中单波束测深技术是在航动态测量,水深具有不可重复性,阐述利用已有的检查线数据进行水下地形测量成果精度评定的3种方法,并在2种不同海域进行验证,成果表明其中的DEM法能够充分利用检查线数据,实现较全面反映水下地形测量成果精度。
Single beam sounding in underwater terrain data acquisition technology is a dynamic measurement in sailing,and water depth is non-repeatability.To tackle these problems,we used the existing inspection data to analyze three accuracy evaluation methods for underwater topographic survey,and verified them in two different water areas.The results show that the DEM method can make full use of check line data and reflect the accuracy of underwater topographic survey results more comprehensively.
