halcon euler_number函数介绍
euler_number(Regions : : : EulerNumber)
euler_number计算欧拉数,
即,连接部件的数量与孔的数量之差。
如果传递多个区域,则结果存储在元组中,
元组中值的索引对应于输入中区域的索引。
例程
gen_circle (Circle, 200, 200, 100.5)
gen_circle (Circle1, 200, 150, 20)
gen_circle (Circle2, 200, 250, 20)
difference (Circle, Circle2, RegionDifference)
difference (RegionDifference, Circle1, RegionDifference)
euler_number (RegionDifference, EulerNumber)
区域RegionDifference内有两个孔洞,一个连接组件,
所计算
欧拉数为1-2=-1个
