// 描述: 通孔填锡率测量算子（倾斜投影几何法），基于四椭圆ROI
|
||
// 功能:
|
||
// - 样品倾斜约45°放置，利用投影位移关系计算填锡率
|
||
// - 四个椭圆定义：
|
||
// E1 = 通孔底部轮廓
|
||
// E2 = 通孔顶部轮廓
|
||
// E3 = 填锡起点（与E1重合，代表0%填锡）
|
||
// E4 = 填锡终点（锡实际填充到的高度）
|
||
// - 填锡率 = |E4中心 - E3中心| / |E2中心 - E1中心| × 100%
|
||
// - 纯几何方法，不依赖灰度分析
|
||
// - IPC-610 THT 分级判定（Class 1/2/3）
|
||
// 算法: 倾斜投影位移比例
