| 摘 要： | 提出了一种用心形线作为参考边界代替圆参考的近似算法。详细介绍了心形线边界的求法 (包括最小外接心形线求法、最大内切心形线求法和最小区域心形线求法等 3种方法 )以及进行不圆度误差评定的方法。并给出了整个程序流程图 ,经实际运行结果表明 ,该算法较普通算法速度要提高很多 ,特别是最小区域算法较之其它计算方法更为简捷。

| Abstract: | A proximate algorithm adopting the heart-shaped loop reference boundary was put forward. Solutions to heart-shaped loop including the solution to minimal circumscribed heart-shaped loop, maximal inscribed heart-shaped loop and minimal zone heart-shaped loop and the error evaluations of non-perimeters were suggested in detail. The whole process flow charts were also drawn out. The practical process results indicate that the rate of this algorithm was greatly improved contrasted to the average algorithms and the minimal zone algorithms.. |
