| 摘 要： | 介绍一种应用样条函数法对有限原木数据进行曲线拟合的方法。此方法具有采集数据少,曲线拟合准确度高,使用方便等特点。利用电子计算机高精度绘图功能,可以很方便地绘制出原木几何形体不同视角的图形,为确定合理最佳锯剖方案提供有力的工具。

| Abstract: | The paper introduces a new method of the curve-fitting the finite discrete points in log with the method of spline function. The method has advantages of less data acquired, higher accuracy in curve-fitting, casier to use, etc. Making use of high-precision drawing function of computer, we can achieve the geometric shapes of log in different visual angles, and determine optimum saw-cutting scheme. |
