摘　　要：针对逆向工程中圆柱体几何特征参数的评估方法进行了研究,提出了一种新的特征参数评估方法,其主要思想是将圆柱体几何特征参数的求解过程分为2部分通过圆柱体高斯图上的约束平面求解其轴线方向向量;求解已知轴线方向向量的圆柱体。最后,给出了验证实例。This paper presents a new method for evaluating cylinder geometric parameters in the reverse engineering. The main idea of this approach is to separate the evaluation process of the cylinder geometric parameters into two distinct steps. The first step is to in extract a constrained plane in the Gaussian image of the cylinder to yield the direction of the cylinder. In the second step, the cylinder of known direction is extracted in the set of points. Experimental results demonstrate that this method is effective for the evaluation of cylinder geometric parameters.
