摘　　要：提出一种三维地层剖面的实时显示方法。该方法利用给定的数字高程模型数据及三次样条函数拟合曲线构造剖面轮廓线,以有效解决三维地层模型内部的可视化问题。为便于施工,在疏浚过程中采用声纳数据动态调整模型。实验结果表明,该方法计算速度快、精度高,可以达到实时显示的效果,并能提高耙吸挖泥船疏浚的质量,减少对环境的影响。This paper presents a real-time display method of three-dimensional strata profile, this method uses the given Digital Elevation ModeI（DEM） data, it adopts cubic spline function curve to structure its outline line, it effectively solves the internal Visualization of three-dimensional strata model. During the dredging, it uses sonar data to adjust the model dynamically for construction. Experimental results show that this method has fast calculation speed, high precision, the effect of real-time display can be achieved, and effectively improves the quality of dredging in trailing suction hopper dredger, reduces environmental impact.
