原木8点检测4点组合回归形状描述方法的研究

Research on the Describing Theory Using Eight Points Inspection and Four Points Combining Regression

介绍了利用8个检测点对圆木进行检测,取其中任意4个点进行组合,从而建立关于原木截面形状的二次仿真数学模型。依据这个原木数学模型,利用试验所得的参数,构建原木外形包络面数学模型,并进一步建立计算机描述系统,实现原木形状计算机仿真和检测自动化。

In this paper,eight points on the log are used and four of them are combined freely.At the same time,the second time simulation mathematic modle has been presented.And so,according perfect log mathematic modle theory and using practical inspection data,we can establish the log's profile mathematic modle.And more,we may establish the computer describing system and the log's profile can be drawn on computer' screen.
