| 摘 要： | 用全站仪对船舱进行分段精确测量,取得各截面上测点的准确数据坐标。建立船舶舱数学模型,采用B样条方法对所测数据进行曲线拟合,形成数学舱图。利用Matlab计算舱剖面相应高度的截面面积,再积分求出相应高度的型容积,扣除舱内部构件体积,得出正平容积表。对船舶实际状态的型容积进行容积修正,同时扣除相应高度构件的体积,得出在不同高度不同状态下的舱容修正表。将两表对照使用,得出液货舱内准确的液货体积。

| Abstract: | In this paper,the cargo hold is accurately measured with the Total Station instrument which is a modern electronic measuring instrument and the coordinate data at every cross section is gathered.The mathematical model is established with the method of B spine interpolation.With the help of the MATLAB software,the corresponding height profile cross-section area is found,the molded capacity can be found through integration calculation and the sheet of the tank capacity in the upright condition can be work out... |
