## 核心哲学
`vision-action-evolution-loop` 定义了抽象的五阶段闭环。
本 Skill 是它的**具体实现层**——聚焦于"如何把2D线条变成3D动作"。
认知节点关系：
```
vision-action-evolution-loop (父: 抽象闭环)
└── diepre-embodied-bridge (本Skill: 具体实现)
├── diepre-vision-cognition (上游: 2D检测)
└── diepre-action-memory (下游: 动作记忆, 未来)
```
## 三大核心认知
### 1. 已知几何估算（非通用3D重建）
包装盒不是复杂场景，是**已知几何体**。不需要 NeRF / Gaussian Splatting / SfM。
```
输入: 2D DXF + FEFCO类型 + 纸板厚度
算法: FEFCO规则引擎 + 2D尺寸 → 3D展开坐标 → 折叠矩阵
输出: 三维空间坐标 (x,y,z) + 折叠顺序 + 面法向量
硬件: M1 Max 轻松运行（纯CPU计算，<100ms）
```
**为什么排除 NeRF/Gaussian Splatting？**
- 包装盒是平面折叠结构，不是复杂3D场景
- NeRF需要数百张照片+GPU集群训练，M1 Max跑不动
- Gaussian Splatting需要密集视角，生产环境不现实
- 已知几何估算：1张照片+FEFCO规则→3D，秒级完成
### 2. MCP 工具链（Tool-Augmented）
OpenCV 管道封装为可调用工具，VLA 模型调用工具而非处理原始图像：
```python
tools = {
"detect_dieline": {
"input": "image_path: str",
"output": "dxf_path: str, confidence: float",
"impl": "diepre_vision.analyze"
},
"estimate_dimensions": {
"input": "dxf_path: str",
"output": "length, width, height, thickness_mm",
"impl": "dimension_estimator.from_dxf"
},
"identify_fefco_type": {
"input": "dxf_path: str, layout_features: dict",
"output": "fefco_type: str (e.g. 0201, 0427)",
"impl": "fefco_classifier.classify"
},
"calculate_fold_sequence": {
"input": "fefco_type: str, dimensions: dict, material: str",
"output": "ordered_steps: list[FoldStep]",
"impl": "fold_planner.plan"
},
"compute_grasp_points": {
"input": "fold_sequence: list[FoldStep], material_thickness: float",
"output": "grasp_points: list[GraspPoint] (xyz + force + angle)",
"impl": "grasp_calculator.compute"
},
"estimate_quality": {
"input": "image_path: str, expected_dimensions: dict",
"output": "quality_score: float, defects: list",
"impl": "quality_checker.evaluate"
}
}
```
### 3. 自迭代进化机制
```
执行任务 → 记录结果 → 提取失败模式 → 调整参数 → 下次优化
具体流程:
1. 每次任务执行完，写入 evolution_log/{task_id}.json:
{
"task_id": "diepre_20260331_001",
"input": {"image": "...", "fefco": "0201", "material": "B flute"},
"execution": {"steps": [...], "timing_ms": 3400},
"result": {"success": false, "fail_step": 3, "error": "grasp_slip"},
"params_used": {"grasp_force": 2.5, "approach_angle": 45}
}
2. 定期扫描 evolution_log/，提取失败模式:
- grasp_slip 在 B flute 上发生频率 73% → 提高抓取力
- fold_sequence 错误在 FEFCO 0427 上频率 40% → 修正折叠规则
3. 更新参数文件 params/evolved_params.json:
{"B_flute_grasp_force": 3.2, "0427_fold_override": [...]}
4. 下次任务加载 evolved_params.json，用优化后参数执行
```
## 安装命令
```bash
clawhub install diepre-embodied-bridge
# 或手动安装
cp -r skills/diepre-embodied-bridge ~/.openclaw/skills/
```
## 调用方式
```python
from skills.diepre_embodied_bridge import DiePreEmbodiedBridge
bridge = DiePreEmbodiedBridge(workspace=".")
# 单次执行
result = bridge.execute(
image_path="path/to/box_photo.jpg",
material="B flute",
thickness_mm=3.0
)
print(result.fefco_type) # "0201"
print(result.dimensions) # {"L": 300, "W": 200, "H": 100}
print(result.fold_sequence) # [FoldStep(...), ...]
print(result.grasp_points) # [GraspPoint(x=150,y=0,z=50,force=3.2), ...]
print(result.quality_score) # 0.92
print(result.confidence) # 0.96
# 自迭代: 注入失败反馈
bridge.record_failure(
task_id="diepre_20260331_001",
fail_step=3,
error_type="grasp_slip",
context={"material": "B flute", "grasp_force": 2.5}
)
# 查看进化状态
stats = bridge.evolution_stats()
print(stats.total_tasks) # 47
print(stats.failure_rate) # 0.12
print(stats.top_failure_modes) # [("grasp_slip", 8), ("fold_error", 4)]
```
