| 摘 要： | 曲线的拟合精度,是衡量反求工程中CAD建模工作成功与否的一个重要标准,针对反求工程中随机扫描所产生的散乱点云数据,在单个数据点满足给定误差的情况下,以数据点与其在曲线上相应参数点之间的距离平方和最小为优化的目标函数,利用遗传规划求解散乱点云数据的精确逼近函数来拟合B样条曲线,并在实验中取得了良好的效果.

| Abstract: | The matching precision of curve is an important criterion for weighing up whether the work of CAD modelling is successful or not in the reverse seeking engineering.Aimed at the disheveled data of points cloud generated by random scanning in the reverse seeking engineering,under the condition of the single data point that satisfies a given error,taking the quadratic sum of distance between the data point and its corresponding parametric point on the curve to be a minimum as the optimized target function,util... |
