Applying the information extracted from numerous hydrographic data of field trials collected by h / hcs - 017, the first set of multi - beam swath bathymeter developed in china, a series of mosaic techniques have been carefully studied in this thesis, including digital terrain model building, statistical error analyzing, hydrographic data mosaicking as well as tides correction and projection of the earth coordinates. finally, standard digital sea - charts and three dimensional seafloor images are successfully developed that are consistent with hydrographic surveying principles
本文利用我國第一臺h hcs ? 017型條帶測深儀的測量數據進行拼圖技術的研究，主要研究的內容有：利用分帶原理對深度數據進行潮汐修正，得到瞬時海面的深度數據；對測深數據進行誤差分析處理，去除野值；將多波束數據進行坐標變換及投影轉換后構建數字地理模型，進而根據海道測量規范繪制標準海圖。 -
