异常面积计算

CALCULATION OF THE ANOMALY AREA

提出一种新的异常面积计算方法———多边形逼近法 ,并给出相应的算法和精度控制方法。采用该方法计算异常面积 ,速度快、精度高 ,具有较好的应用效果。

This paper puts forward a new method for calculating anomaly area—the polygonous approximation method,and gives corresponding algorithm and precision controlling technique.With this method,one can calculate anomaly area rapidly and precisely,thus yielding relatively satisfactory results.
