+# 多视角图片一致性 & 3D/视频生成 技术文档
+
+## 一、系统概述
+
+玉宗珠宝 AI 设计系统支持根据用户选择的品类、颜色、工艺等参数，自动生成多视角设计图（效果图、正面图、侧面图、背面图），并基于这些图片进一步生成 3D 模型和 360 度旋转展示视频。
+
+**核心挑战**：AI 生图模型（如 Seedream 5.0 lite）的"参考图"参数本质上是**风格参考**，而非"同一物体不同角度"的语义理解。因此需要通过多层提示词策略来约束 AI 保持多视角图片的一致性。

+## 三、涉及文件清单
+
+| 文件路径 | 职责 |
+|---------|------|
+| `backend/app/services/design_service.py` | 设计生成主流程，多视角循环、一致性策略协调 |
+| `backend/app/services/prompt_builder.py` | 提示词构建器，品类视角配置、品类专属背面/侧面描述 |
+| `backend/app/services/ai_generator.py` | AI 生图服务，支持 SiliconFlow Kolors 和 Seedream 双模型 |
+| `backend/app/services/ai_3d_generator.py` | 腾讯混元3D 模型生成服务，多视角→3D |
+| `backend/app/services/ai_video_generator_kling.py` | 可灵 AI 多图参考生视频服务 |
+| `backend/app/routers/designs.py` | REST API 路由，收集多视角图片调用 3D/视频服务 |

+| `init_data.sql` | 数据库初始化，包含 prompt_mappings 视角映射 |
+| `frontend/src/components/DesignPreview.vue` | 前端多视角展示与下载 |
+
+---
+
+## 四、品类视角配置
+
+不同品类生成的视角数量和种类不同，定义在 `prompt_builder.py` 的 `CATEGORY_VIEWS` 字典中：
+
+| 品类 | 视角列表 | 视角数 |
+|------|---------|-------|
+| 牌子 | 效果图、正面图、背面图 | 3 |
+| 珠子 | 效果图、正面图 | 2 |
+| 手把件 | 效果图、正面图、侧面图、背面图 | 4 |
+| 雕刻件 | 效果图、正面图、侧面图、背面图 | 4 |
+| 摆件 | 效果图、正面图、侧面图、背面图 | 4 |
+| 随形 | 效果图、正面图、侧面图、背面图 | 4 |
+| 手镯 | 效果图、正面图、侧面图 | 3 |
+| 戒指 | 效果图、正面图、侧面图 | 3 |
+| 耳钉/耳饰/手链/项链/表带 | 效果图、正面图 | 2 |
+
+**生成顺序**：严格按列表顺序，第一张始终是"效果图"（45度英雄镜头），后续视角依次生成。
+
+---
+
+## 五、多视角图片一致性策略（四层保障）
+
+### 第一层：AI 模型级参考机制
+
+位置：`design_service.py` → `_generate_ai_images()` 第 134-183 行
+
+**两种模型的不同一致性方式：**
+
+| 模型 | 一致性机制 | 参数 | 说明 |
+|------|-----------|------|------|
+| SiliconFlow Kolors | seed 复用 | `seed` | 第一张图返回的 seed 值传给后续视角，确保随机过程相同 |
+| Seedream 5.0 lite | 参考图 | `ref_image_url` → `image: [url]` | 第一张图的远程 URL 作为风格参考传入后续视角 |
+
+**代码流程：**
+```python
+shared_seed = None       # Kolors 用: 第一张图的 seed
+first_remote_url = None  # Seedream 用: 第一张图的远程 URL
+
+for idx, view_name in enumerate(views):
+    # 后续视角传入 seed 或参考图 URL
+    ref_url = first_remote_url if idx > 0 else None
+    
+    remote_url, returned_seed = await ai_generator.generate_image(
+        final_prompt, model, seed=shared_seed, ref_image_url=ref_url
+    )
+    
+    # 第一张图保存信息供后续复用
+    if idx == 0:
+        first_remote_url = remote_url
+        if returned_seed is not None:
+            shared_seed = returned_seed
+```
+
+**关键限制**：Seedream 的 `image` 参数本质上是**风格参考**，AI 不能直接理解为"同一个物体的不同角度"，所以需要第二、三、四层提示词来补充约束。
+
+---
+
+### 第二层：一致性前缀（相机位置描述）
+
+位置：`design_service.py` 第 159-172 行
+
+从第 2 张图起（idx > 0），在提示词**最前面**拼接一段一致性约束前缀，按视角名称定制相机位置描述：
+
+```python
+view_angle_map = {
+    "正面图": "moving the camera to face the object directly from the front",
+    "侧面图": "moving the camera 90 degrees to the left side of the object",
+    "背面图": "moving the camera 180 degrees to see the reverse/back side of the object",
+}
+
+consistency_prefix = (
+    f"Photograph the EXACT SAME jade object from the reference image, {angle_desc}. "
+    "The object does NOT move or change - only the camera position changes. "
+    "The shape, size, color, material texture, and all physical features must remain IDENTICAL. "
+)
+
+final_prompt = consistency_prefix + prompt_text
+```
+
+**设计思路**：
+- 强调"EXACT SAME"和"IDENTICAL"强制 AI 保持物体一致
+- 用"相机移动"的摄影术语描述视角变化，而非"生成另一张图"
+- 明确"物体不动，只有相机位置改变"
+
+---
+
+### 第三层：品类专属视角描述
+
+位置：`prompt_builder.py` 第 35-65 行 & 第 197-201 行
+
+不同品类的背面特征差异极大，需要品类专属描述来避免 AI 产生错误理解。
+
+**背面描述（BACK_VIEW_HINTS）：**
+
+| 品类 | 背面特征 | 核心约束 |
+|------|---------|---------|
+| **牌子** | 光滑平面，可能有题款，**绝对没有雕刻图案** | "Do NOT mirror or duplicate the front carving on the back" |
+| **手把件** | 同一件三维雕塑的背面，自然延续 | "natural continuation of the carving from the rear angle" |
+| **雕刻件** | 三维雕塑的背面，雕刻自然延续 | "not a separate or different design" |
+| **摆件** | 三维陈列品的背面 | "form and carving continue naturally" |
+| **随形** | 天然石料表面的背面 | "may show more of the raw jade texture" |
+
+**侧面描述（SIDE_VIEW_HINTS）：**
+
+| 品类 | 侧面特征 |
+|------|---------|
+| **牌子** | 薄片轮廓，5-10mm 厚度 |
+
+**解决的核心问题**：
+牌子品类出现"双面佛"效果 —— 背面也有雕刻图案。真实的玉雕牌子背面是光滑平面。通过 `BACK_VIEW_HINTS["牌子"]` 强制约束 AI：
+> "The reverse/back side of a jade pendant plaque is traditionally a smooth, flat, polished surface. It may have a brief inscription or seal mark, but it must NOT have any carved figure, face, or decorative relief pattern."
+
+**应用时机**：在 `build_prompt()` 构建提示词时，根据视角名称和品类名称自动追加：
+```python
+if view_name == "背面图" and category_name in BACK_VIEW_HINTS:
+    parts.append(BACK_VIEW_HINTS[category_name])
+elif view_name == "侧面图" and category_name in SIDE_VIEW_HINTS:
+    parts.append(SIDE_VIEW_HINTS[category_name])
+```
+
+---
+
+### 第四层：数据库视角映射提示词
+
+位置：`prompt_mappings` 表（mapping_type='view'）
+
+每个视角有标准化的英文摄影术语描述，存储在数据库中，支持后台热更新：
+
+| 视角 | 英文描述 |
+|------|---------|
+| 效果图 | `three-quarter view at 45-degree angle, hero shot showing the complete jade artwork with depth and dimension, single object on pure white background` |
+| 正面图 | `front view, camera positioned directly in front of the object facing it straight-on, showing only the front carved surface, single object on pure white background` |
+| 侧面图 | `side view, camera positioned at exactly 90 degrees to the left of the object, showing the edge profile and thickness, single object on pure white background` |
+| 背面图 | `back view, camera positioned directly behind the object at 180 degrees, showing the reverse side, single object on pure white background` |
+
+**设计特点**：
+- 使用纯**摄影术语**（camera positioned, facing, straight-on）
+- 精确的**角度度数**（45°、90°、180°）
+- 统一的**纯白背景**要求（pure white background）
+- 强调**单一物体**（single object）避免生成多个物体
+
+---
+
+### 四层策略的组合效果
+
+以"牌子"品类的背面图为例，最终提示词结构：
+
+```
+[第二层：一致性前缀]
+Photograph the EXACT SAME jade object from the reference image, 
+moving the camera 180 degrees to see the reverse/back side of the object. 
+The object does NOT move or change - only the camera position changes. 
+The shape, size, color, material texture, and all physical features must remain IDENTICAL.
+
+[常规提示词内容]
+Chinese Hetian nephrite jade pendant plaque, 
+natural Hetian nephrite jade with warm luster, 
+featuring dragon-phoenix auspicious pattern, 
+relief carving with raised design emerging from surface, 
+...
+
+[第四层：视角映射]
+back view, camera positioned directly behind the object at 180 degrees, 
+showing the reverse side, single object on pure white background,
+
+[第三层：品类专属背面描述]
+IMPORTANT: The reverse/back side of a jade pendant plaque is traditionally 
+a smooth, flat, polished surface. It may have a brief inscription or seal mark, 
+but it must NOT have any carved figure, face, or decorative relief pattern. 
+The back is plain and minimalist. Do NOT mirror or duplicate the front carving on the back.
+
+[质量后缀]
+professional jewelry product photography, studio lighting setup, 
+pure white background, ultra-detailed, sharp focus, 8K resolution, 
+photorealistic rendering, high-end commercial quality
+```
+
+加上 [第一层] Seedream API 的 `image` 参数传入第一张效果图作为风格参考。
+
+---
+
+## 六、3D 模型生成
+
+### 6.1 技术方案
+
+- **服务**：腾讯混元3D 专业版（Hunyuan3D Pro）
+- **API 认证**：TC3-HMAC-SHA256 签名
+- **输入**：主图 + 多视角图片
+- **输出**：ZIP 包（包含 GLB/OBJ/FBX/STL 多种格式）
+
+### 6.2 多视角图片收集
+
+位置：`designs.py` → `generate_3d_model()` 第 329-339 行
+
+```python
+# 收集所有多视角图片 URL 和视角名称
+image_urls = []
+view_names = []
+if design.images:
+    for img in sorted(design.images, key=lambda x: x.sort_order):
+        if img.image_url:
+            image_urls.append(img.image_url)
+            view_names.append(img.view_name or "效果图")
+```
+
+### 6.3 视角映射
+
+位置：`ai_3d_generator.py` 第 121-126 行
+
+混元3D API 的 `MultiViewImages` 参数支持指定每张图的视角类型：
+
+```python
+_VIEW_NAME_MAP = {
+    "侧面图": "left",
+    "背面图": "back",
+}
+```
+
+**主图选择逻辑**：正面图优先 → 效果图次之 → 否则取第一张
+
+```python
+for url, name in zip(image_urls, view_names):
+    if name == "正面图" and not main_url:
+        main_url = url                    # 正面图作为主图
+    elif name in _VIEW_NAME_MAP:
+        multi_views.append({              # 侧面/背面作为辅助视角
+            "ViewType": _VIEW_NAME_MAP[name], 
+            "ViewImageUrl": url
+        })
+    elif not main_url:
+        main_url = url                    # 效果图或其他作为备选主图
+```
+
+### 6.4 URL 转换
+
+位置：`ai_3d_generator.py` → `_to_public_url()` 第 129-138 行
+
+第三方 API 需要外网可访问的完整 URL，本地存储路径（/uploads/xxx）需要拼接域名：
+
+```python
+def _to_public_url(url: str) -> str:
+    if url and url.startswith("/uploads/"):
+        base_domain = get_config_value("SITE_DOMAIN", "http://c02.wsg.plus")
+        return f"{base_domain}{url}"
+    return url
+```
+
+> **注意**：服务器仅支持 HTTP，不支持 HTTPS（HTTPS 会 ERR_CONNECTION_REFUSED）。
+
+### 6.5 生成流程
+
+```
+收集多视角图片 → 转换为外网URL → 选择主图/辅助视角
+    → 提交 SubmitHunyuanTo3DProJob (ImageUrl + MultiViewImages)
+    → 轮询 QueryHunyuanTo3DProJob (每5秒，最多120次≈10分钟)
+    → 下载 ZIP 解压提取 .glb → 保存到 /uploads/models/
+```
+
+### 6.6 结果存储
+
+3D 模型 URL 保存到**第一张 DesignImage** 的 `model_3d_url` 字段。同时保留 ZIP 包（包含 GLB/OBJ/FBX/STL）供用户完整下载。
+

+
+## 七、视频生成
+
+### 7.1 技术方案
+
+- **服务**：可灵 AI（Kling）多图参考生视频
+- **API 端点**：`https://api-beijing.klingai.com/v1/videos/multi-image2video`
+- **API 认证**：JWT（HS256，Access Key + Secret Key 签发，30 分钟有效期）
+- **输入**：1-4 张参考图片 + 提示词
+- **输出**：MP4 视频
+
+### 7.2 多视角图片收集
+
+位置：`designs.py` → `generate_video()` 第 273-280 行
+
+```python
+# 收集多视角图片 URL
+image_urls = []
+if design.images:
+    for img in sorted(design.images, key=lambda x: x.sort_order):
+        if img.image_url:
+            image_urls.append(img.image_url)
+if not image_urls and design.image_url:
+    image_urls.append(design.image_url)  # 兼容旧数据：只有 design.image_url
+```
+
+### 7.3 核心优势
+
+可灵 AI 的多图参考生视频 API **原生支持传入 1-4 张参考图**，AI 会理解为同一物体的多个角度参考，生成单品旋转展示视频。这是选择可灵 AI 的核心原因。
+
+### 7.4 视频提示词
+
+默认提示词（可通过数据库 `VIDEO_PROMPT` 配置覆盖）：
+
+```
+精美玉雕工艺品在专业珠宝摄影棚内展示，
+纯白色背景，柔和的珠宝摄影灯光，
+玉石作品放在旋转展台上缓慢平稳地旋转360度，
+展示正面、侧面、背面全貌，
+展现玉石温润的质感、细腻的雕刻纹理和通透的光泽，
+电影级画质，微距细节感，平稳流畅的转台旋转
+```
+
+### 7.5 API 参数
+
+```python
+payload = {
+    "model_name": "kling-v1-6",      # 可灵 v1.6 模型
+    "image_list": image_list,          # [{"image": "url"}, ...]，最多4张
+    "prompt": prompt,                  # 视频提示词
+    "mode": "pro",                     # 高品质模式（Pro）
+    "duration": "5",                   # 视频时长（5秒或10秒）
+    "aspect_ratio": "1:1",            # 正方形比例
+}
+```
+
+### 7.6 生成流程
+
+```
+收集多视角图片(最多4张) → 转换为外网URL → 构建image_list
+    → 提交 POST /v1/videos/multi-image2video
+    → 轮询 GET /v1/videos/multi-image2video/{task_id} (每5秒，最多120次)
+    → 下载 MP4 → 保存到 /uploads/videos/
+```
+
+### 7.7 JWT 认证细节
+
+```python
+headers = {"alg": "HS256", "typ": "JWT"}
+payload = {
+    "iss": access_key,        # 签发者 = Access Key
+    "exp": now + 1800,        # 30 分钟过期
+    "nbf": now - 5,           # 允许 5 秒时钟偏差
+    "iat": now,               # 签发时间（必须包含！）
+}
+token = jwt.encode(payload, secret_key, algorithm="HS256", headers=headers)
+```
+
+> **踩坑记录**：`headers` 中的 `typ` 和 `payload` 中的 `iat` 字段缺一不可，否则返回 401 认证失败。
+
+---
+
+## 八、图片持久化存储
+
+### 8.1 问题背景
+
+第三方 AI 服务（火山引擎 Seedream）生成的图片 URL 是**临时链接**，一段时间后会过期失效（返回 NoSuchKey 错误）。
+
+### 8.2 解决方案
+
+生成图片后立即下载到本地 `uploads/designs/` 目录持久化存储：
+
+```python
+async def _download_image_to_local(remote_url, design_id, idx):
+    filename = f"{design_id}_{idx}_{uuid.uuid4().hex[:8]}.png"
+    local_path = os.path.join(designs_dir, filename)
+    # 下载远程图片
+    async with httpx.AsyncClient(timeout=60, follow_redirects=True) as client:
+        resp = await client.get(remote_url)
+        with open(local_path, "wb") as f:
+            f.write(resp.content)
+    return f"/uploads/designs/{filename}"
+```
+
+### 8.3 URL 格式
+
+- **本地存储路径**：`/uploads/designs/{design_id}_{idx}_{随机8位}.png`
+- **外网访问 URL**：`http://c02.wsg.plus/uploads/designs/{design_id}_{idx}_{随机8位}.png`
+
+---
+
+## 九、前端展示与下载
+
+### 9.1 多视角切换
+
+前端 `DesignPreview.vue` 通过 Tab 栏展示多视角图片，用户点击不同视角 Tab 切换显示。
+
+### 9.2 图片下载
+
+前端直接通过 `fetch()` 下载当前视角图片（不走后端 download 接口），确保下载的是当前展示的视角图片：
+
+```typescript
+const handleDownload = async () => {
+  const imgUrl = currentImageUrl.value  // 当前视角的图片URL
+  const res = await fetch(imgUrl)
+  const blob = await res.blob()
+  // 创建 <a> 标签触发下载
+  _downloadBlob(blob, downloadFilename.value)
+}
+```
+
+> **踩坑记录**：之前使用后端 `/api/designs/{id}/download` 接口，该接口只返回 `design.image_url`（第一张效果图），导致所有视角下载的都是效果图。
+
+---
+
+## 十、数据模型
+
+### DesignImage 表
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| id | Integer | 主键 |

+
+---
+
+## 十二、成本估算
+
+| 服务 | 单价 | 说明 |
+|------|------|------|
+| Seedream 5.0 lite 生图 | ≈ 0.22 元/张 | 4 个视角 ≈ 0.88 元 |
+| 腾讯混元3D 专业版 | 按量计费 | 单次 3D 生成 |
+| 可灵 AI 视频 Pro 5s | ≈ 7 元/次 | Pro 模式，5 秒时长 |
+
+**单次完整设计成本**（4视角品类）：≈ 0.88（生图）+ 混元3D + 7（视频）
+
+---
+
+## 十三、已知问题与踩坑记录
+
+| 问题 | 原因 | 解决方案 |
+|------|------|---------|
+| 背面图出现"双面佛" | Seedream 参考图是风格参考，AI 把正面图案复制到背面 | 品类专属 BACK_VIEW_HINTS + 一致性前缀 |
+| 图片过期 404 (NoSuchKey) | 火山引擎临时链接过期 | 生成后立即下载到本地持久化 |
+| HTTPS 连接被拒绝 | 服务器未配置 HTTPS | `_to_public_url` 使用 `http://` |
+| 下载所有视角都是效果图 | 后端 download 接口只返回 image_url | 前端改用 fetch 直接下载当前视角 URL |
+| 可灵 AI 401 认证失败 | JWT 缺少 typ header 和 iat 字段 | 显式传入 headers={typ:JWT} 和 iat |
+| 混元3D 字段名错误 | ViewImage 应为 ViewImageUrl | 使用正确的 ViewImageUrl 字段 |
+| 前端更新不生效 | 只上传了 .vue 源文件 | 前端是编译型项目，需上传编译后的 dist/ |
+
+---
