【摘要】：针对当前等深线的化简主要依靠经验和手工方法实施,其自动化简仍未取得实质性突破的现状。从等深线化简的安全性约束出发,阐释了蛇模型的基本内涵,分析和计算了蛇模型曲线所受的力,明确了蛇模型点的安全约束方法,推导了蛇模型的能量公式,并实现了基于蛇模型的等深线自动化简。试验结果表明,采用该算法化简后的等深线能够很好地遵守安全性约束准则;蛇模型算法可以用来实现等深线的自动化简。
[Abstract]:At present, the simplification of isobath mainly depends on experience and manual method, but its automation simplification still has not made a substantial breakthrough. Based on the security constraints of isobaric simplification, the basic connotation of snake model is explained, the force of snake model curve is analyzed and calculated, the security constraint method of snake model point is defined, and the energy formula of snake model is deduced. The automation of isobath based on snake model is realized. The experimental results show that the isobath can comply with the security constraint criterion well, and the snake model algorithm can be used to realize the automatic simplification of the isobath.
