feat: 接口1/6 标注层字号上调一档 + 眉心改用 9 号点定位

- annotation: 自适应字号系数 0.017→0.020（下限 8→9），标注文字更大更清晰
- measure: _brow_center 只取 FaceMesh 9 号点（眉间上点），不再与 151 取中点

+# 脸型判断规则优化报告
+
+> 基于 Mediapipe 468 点人脸关键点的脸型分类系统  
+> 优化日期：2026-07-28
+
+---
+
+## 一、优化总览
+
+### 原始规则主要问题
+
+| 问题 | 说明 |
+|------|------|
+| **规则冲突** | 7条 if 规则可能同时匹配，无优先级机制 |
+| **特征定义模糊** | `width_ratio`、`chin_narrowness` 等未给出精确计算方式 |
+| **关键点不足** | 额头宽度用 234/454（颧骨点）而非太阳穴点，导致测量不准 |
+| **无置信度** | 硬判断，混合脸型无处理 |
+| **阈值经验性** | 阈值未经统计校准，边界处容易误判 |
+| **缺少归一化** | 不同距离拍的照片结果不一致 |
+
+### 优化策略
+
+1. **精确特征提取**：增加关键点，所有测量归一化
+2. **评分制分类**：每个脸型计算匹配度分数（0-100），取最高分
+3. **置信度输出**：报告 Top-1 / Top-2 分差，判断是否为混合脸型
+4. **优先级仲裁**：分数接近时按"特异性优先"原则仲裁
+5. **鲁棒性增强**：clamp 防止除零、NaN，角度计算增加 3D 投影

+
+---
+
+## 四、关键参数含义与阈值设定理由
+
+### aspect_ratio（面部长宽比）
+
+```
+计算方式：face_width / face_height
+```
+
+| 范围 | 脸型倾向 | 理由 |
+|------|----------|------|
+| < 0.70 | 长形脸 | 脸长明显大于宽 |
+| 0.70-0.85 | 鹅蛋/心形/瓜子 | 多数亚洲人的标准比例 |
+| 0.85-1.0 | 圆形/方形 | 脸宽接近脸长 |
+
+**设定理由**：根据 Farkas 面部测量数据，东亚人群面宽/面高比通常在 0.75-0.88 之间。0.85 和 0.70 是自然的分界点。
+
+### jaw_angle（下颌角度）
+
+```
+计算方式：下巴底为顶点，向左右下颌角做向量，计算夹角
+```
+
+| 范围 | 脸型倾向 | 理由 |
+|------|----------|------|
+| < 125° | 方形脸 | 下颌角锐利，线条硬朗 |
+| 125-140° | 鹅蛋/瓜子/心形 | 自然柔和 |
+| > 140° | 圆形脸 | 下颌圆润 |
+
+**设定理由**：下颌角是区分方形和圆形的关键。方形脸 gonion 角通常在 110-125°，圆形脸在 140-155°。
+
+### taper_ratio（额头→下巴收窄比例）
+
+```
+计算方式：(forehead_width - chin_width) / forehead_width
+```
+
+| 范围 | 脸型倾向 |
+|------|----------|
+| < 0.05 | 圆形/方形（无收窄）|
+| 0.05-0.15 | 鹅蛋/长形（适度收窄）|
+| > 0.20 | 心形/瓜子（明显收窄）|
+
+### chin_sharpness（下巴尖锐度）
+
+```
+计算方式：chin_width / jaw_width
+```
+
+| 范围 | 脸型倾向 |
+|------|----------|
+| < 0.50 | 尖下巴（瓜子/心形）|
+| 0.50-0.65 | 适中（鹅蛋）|
+| > 0.65 | 宽下巴（圆形/方形）|
+
+---
+
+## 五、优化点说明
+
+### 5.1 从「硬规则」到「评分制」
+
+**原始方案**：每条规则是独立的 if 判断，可能同时满足多条，也可能都不满足。
+
+**优化方案**：每种脸型计算 0-100 的匹配度分数，取最高分。
+
+```python
+# 原始：可能冲突
+if 0.85 <= width_ratio <= 1.0:   # 圆形脸
+    ...
+if jaw_angle < 130:              # 方形脸
+    ...
+# 同一张脸可能同时满足或都不满足！
+
+# 优化：评分制，必然有结果
+scores = {'圆形脸': 72.5, '方形脸': 45.0, ...}
+# 取最高分 → 圆形脸，置信度 72.5/total
+```
+
+### 5.2 三角窗评分函数
+
+每个特征的贡献不是 0/1 的硬切换，而是使用**三角窗函数**平滑过渡：
+
+```
+        满分
+         /\
+        /  \
+       /    \
+      /      \
+_____/__      \____
+   low peak   high
+```
+
+好处：在阈值边界处不会产生跳变，结果更稳定。
+
+### 5.3 增加关键点精度
+
+| 测量 | 原始方案 | 优化方案 |
+|------|----------|----------|
+| 额头宽度 | 234-454（颧骨点）| 127-356（太阳穴点）|
+| 下巴宽度 | 未明确 | 136-365（下巴缘）|
+| 下颌宽度 | 172-397 | 172-397（保持，下颌角）|
+
+**改进理由**：234/454 是颧弓最外侧点，用它们测"额头宽度"会把颧骨宽度误当额头宽度。改用 127/356 太阳穴点更准确。
+
+### 5.4 混合脸型检测
+
+当 Top-1 和 Top-2 分差小于 8 分时，判定为混合脸型：
+
+```python
+# 例：鹅蛋脸 65 分，瓜子脸 62 分 → 分差 3 < 8
+# 输出："鹅蛋脸（偏瓜子脸）"
+```
+
+### 5.5 置信度输出
+
+```python
+confidence = best_score / total_score
+# > 0.25  → 高置信度，结果明确
+# 0.18-0.25 → 中等，有一定混合
+# < 0.18  → 低置信度，建议人工复核
+```
+
+---
+
+## 六、边界情况处理建议
+
+### 6.1 人脸偏转（非正脸）
+
+```python
+# 检测左右对称性，偏转过大时拒绝判断
+def check_symmetry(landmarks):
+    left_eye  = landmarks[33]
+    right_eye = landmarks[263]
+    nose_tip  = landmarks[168]
+
+    eye_mid_x = (left_eye.x + right_eye.x) / 2
+    symmetry = abs(eye_mid_x - nose_tip.x)
+
+    if symmetry > 0.03:  # 偏移过大
+        return False, "检测到人脸偏转，建议正脸拍摄"
+    return True, ""
+```
+
+### 6.2 表情影响
+
+```python
+# 微笑会改变下巴形状，检测嘴部张开度
+def check_expression(landmarks):
+    upper_lip = landmarks[13]
+    lower_lip = landmarks[14]
+    mouth_open = abs(upper_lip.y - lower_lip.y)
+
+    if mouth_open > 0.05:  # 嘴巴张大
+        return False, "检测到嘴巴张开，建议自然闭合"
+    return True, ""
+```
+
+### 6.3 多特征都低分
+
+```python
+if best_score < 25.0:
+    return "无法确定", 0.0, {"reason": "特征不够明显，无法准确分类"}
+```
+
+### 6.4 与正脸自拍的差异
+
+建议在分类前对图像做正脸对齐（使用 Mediapipe 的 transform），确保额头在上、下巴在下，左右对称。
+
+### 6.5 性别/年龄差异
+
+男性下颌通常更宽，女性下巴更尖。分类阈值可以考虑：
+
+```python
+# 如果有性别信息（可由另一个分类器提供）
+if gender == 'male':
+    jaw_angle_threshold += 3   # 男性下颌角自然偏小
+else:
+    chin_sharpness_threshold -= 0.03  # 女性下巴自然偏尖
+```
+

+
+## 七、实现建议和注意事项
+
+### 7.1 预处理
+
+```python
+import mediapipe as mp
+
+mp_face_mesh = mp.solutions.face_mesh
+
+with mp_face_mesh.FaceMesh(
+    static_image_mode=True,
+    max_num_faces=1,
+    refine_landmarks=True,        # 使用 478 点（多了虹膜点）
+    min_detection_confidence=0.5,
+) as face_mesh:
+    results = face_mesh.process(rgb_image)
+    if results.multi_face_landmarks:
+        face_shape, conf, details = classify_from_mediapipe(
+            results.multi_face_landmarks
+        )
+```
+
+### 7.2 性能注意事项
+
+- Mediapipe FaceMesh 在 CPU 上 ~10ms/帧，足够实时
+- 关键点 z 坐标精度有限，距离计算建议用 (x, y) 2D 即可
+- 如需更高精度，可用 `refine_landmarks=True` 获取 478 点
+
+### 7.3 阈值校准
+
+当前阈值基于以下来源综合设定：
+
+1. **Farkas 面部测量学数据**（经典人体测量参考）
+2. **亚洲人脸型分布统计**（鹅蛋脸和瓜子脸比例较高）
+3. **Mediapipe 归一化坐标特性**（坐标已归一化到 0-1）
+
+建议在实际部署后收集样本数据进行微调：
+
+```python
+# 收集误分类案例，统计特征分布
+# 使用 ROC 曲线优化各阈值
+```
+
+### 7.4 2D vs 3D 距离
+
+Mediapipe 返回的 landmark 包含 z 坐标，但 z 精度不如 x/y。建议：
+
+```python
+# 推荐方案：仅用 x, y 计算（忽略 z）
+def pt_2d(idx):
+    lm = landmarks[idx]
+    return np.array([lm.x, lm.y])
+
+# 高精度方案：用 z 但加权降低
+def pt_weighted(idx):
+    lm = landmarks[idx]
+    return np.array([lm.x, lm.y, lm.z * 0.5])  # z 权重减半
+```
+
+### 7.5 与原始规则的对比
+
+| 维度 | 原始规则 | 优化后 |
+|------|----------|--------|
+| 判断方式 | 硬 if-else（可能冲突/遗漏）| 评分制（必然有结果）|
+| 关键点 | 12 个 | 16 个（增加太阳穴、下巴缘点）|
+| 特征数 | 5-6 个 | 15 个（含复合特征）|
+| 输出 | 单一标签 | 标签 + 置信度 + 混合脸型 |
+| 边界处理 | 无 | 三角窗平滑 + 低分兜底 |
+| 可调性 | 改阈值需要理解全部分支 | 改 `peak` 值即可微调 |
+| 代码行数 | ~60 行 | ~300 行（含注释）|
+
+---
+
+## 八、测试用例参考
+
+```python
+# 单元测试伪代码
+test_cases = [
+    # (features_dict, expected_shape)
+    ({'aspect_ratio': 0.92, 'jaw_angle': 148, 'taper_ratio': 0.03,
+      'chin_sharpness': 0.75, 'width_uniformity': 0.06,

+      'face_curve_score': 0.19, ...}, '鹅蛋脸'),
+
+    # ... 更多测试用例
