+# CardDex 卡牌检测 Demo — Flutter 开发方案
+
+> **目标**：复刻 CardDex 本地 TF Lite 目标检测 + 卡片定位能力  
+> **周期**：~3.5 天（单人）  
+> **依赖**：CardDex APK 内提取的 `detect.tflite`（COCO 通用检测模型，4MB）
+
+---
+
+## 一、架构概览
+
+```
+┌──────────────────────────────────────┐
+│  Flutter UI                           │
+│  camera_preview + detection_overlay   │
+├──────────────────────────────────────┤
+│  TFLite Detector Service              │
+│  ├─ 模型加载 (detect.tflite)           │
+│  ├─ 图像预处理 (300×300 RGB)           │
+│  ├─ 推理 (输出 boxes/classes/scores)   │
+│  └─ NMS 后处理 (IoU 去重)             │
+├──────────────────────────────────────┤
+│  Camera Plugin (拍照)                  │
+└──────────────────────────────────────┘
+```
+
+**核心流程**：拍照 → 缩放到 300×300 → TF Lite 推理 → NMS 去重 → 画框展示

+### 4.5 检测框渲染 — `detection_painter.dart`
+
+```dart

+  final List<Detection> detections;
+
+  DetectionPainter(this.detections);
+
+  @override
+  void paint(Canvas canvas, Size size) {
+    final paint = Paint()
+      ..color = Colors.green
+      ..style = PaintingStyle.stroke
+      ..strokeWidth = 3.0;
+
+    final textStyle = TextStyle(
+      color: Colors.white,
+      fontSize: 14,
+      backgroundColor: Colors.green.withOpacity(0.8),
+    );

+          text: '${det.label} ${(det.confidence * 100).toStringAsFixed(0)}%',
+          style: textStyle,
+        ),
+        textDirection: TextDirection.ltr,
+      );
+      tp.layout();
+      tp.paint(
+        canvas,
+        Offset(det.boundingBox.left, det.boundingBox.top - tp.height),
+      );
+    }
+  }
+
+  @override
+  bool shouldRepaint(covariant CustomPainter oldDelegate) => true;
+}
+```
+
+---
+
+## 五、模型提取
+
+```bash
+# 从 CardDex APK 提取模型和标签
+cd apk_analysis/recognize/apk_extracted_carddex
+unzip com.card.dex.identifier.detect.apk \
+  "assets/flutter_assets/assets/ml/detect.tflite" \
+  "assets/flutter_assets/assets/ml/labelmap.txt" \
+  -d ../../../carddex_demo/assets/ml/
+```
+
+---
+
+## 六、构建与运行
+
+```bash
+# 1. 创建 Flutter 项目
+flutter create carddex_demo
+cd carddex_demo
+
+# 2. 添加依赖（编辑 pubspec.yaml）
+
+# 3. 复制模型文件到 assets/ml/
+
+# 4. 替换 lib/ 下的代码
+
+# 5. 运行（需要真机，模拟器无相机）
+flutter run
+```
+
+---
+
+## 七、关键注意事项
+
+### 7.1 模型输出格式适配
+
+CardDex 用的是 SSD MobileNet，输出张量取决于具体的 TFLite 模型。如果上面的输出索引不对，需要先用工具查看：
+
+```bash
+# 查看模型输入输出信息
+python3 -c "
+import tensorflow as tf
+interpreter = tf.lite.Interpreter(model_path='assets/ml/detect.tflite')
+print('Input:', interpreter.get_input_details())
+print('Output:', interpreter.get_output_details())
+"
+```
+
+### 7.2 平台配置
+
+**iOS** (`ios/Podfile`)：确保最低版本 ≥ 12.0，并添加相机权限描述。  
+**Android** (`android/app/build.gradle`)：`minSdkVersion` ≥ 21。
+
+### 7.3 性能
+
+- `detect.tflite` ~4MB，推理耗时约 50-200ms（取决于设备）
+- 拍照后单次推理，不做实时帧，性能无忧
+- GPU delegate 可选，配置方法：`Interpreter.fromAsset('detect.tflite', options: InterpreterOptions()..useGpuDelegateWhenAvailable = true)`
+
+### 7.4 局限
+
+| 局限 | 说明 | 后续方向 |
+|------|------|---------|
+| 只能定位，不能分类 | COCO 标签里没有"卡牌"，检测框内的物体不知道是什么卡 | 自训卡牌分类模型或接 API |
+| 模型不针对卡牌优化 | 卡片是矩形平面物体，COCO 模型对此场景精度一般 | 用卡牌数据 fine-tune |
+| 多卡同框效果差 | SSD 对小目标和密集目标检测能力有限 | 换 YOLO-NAS 或 RT-DETR |
+
+---
+
+## 八、Demo 验收标准
+
+- [ ] 打开 App 显示相机预览
+- [ ] 对准一张卡牌拍照
+- [ ] 画面出现绿色检测框 + 标签 + 置信度
+- [ ] 对准其他物体（杯子、手机等）也能检测
+- [ ] 无明显崩溃或 ANR
+
+---
+
+## 九、进阶方向（Demo 后）
+
+| 阶段 | 内容 | 预估 |
+|------|------|------|
+| **Phase 2** | 替换为卡牌专用检测模型（自训练） | 1 周 |
+| **Phase 3** | 接入服务端 API 做卡牌分类 | 3 天 |
+| **Phase 4** | 实时帧推理 + GPU 加速 | 3 天 |
+| **Phase 5** | 多卡同框检测 + 批量识别 | 1 周 |

+# Card Scan Demo 说明
+
+> 对照《集换社_反编译分析报告》（v3.23.15）与本仓库当前实现，说明 demo 定位、流水线与差异。
+
+---
+
+## 1. 背景：集换社里的「卡牌扫描」
+
+集换社是 TCG 卡牌 **C2C 交易平台**（包名 `com.jihuanshe`），卡牌扫描只是完整业务中的一环，不是独立工具 App。
+
+反编译报告里与扫描相关的关键结论：
+
+| 项 | 集换社侧证据 |
+|----|--------------|
+| 入口 | `CardScanActivity` / `CardScanAlbumActivity` / `CaptureActivity` / `ScanActivity` |
+| 相机 | CameraX（`MetadataHolderService` 等） |
+| 识别 | Google ML Kit（`libmlkitcommonpipeline.so` ~8.4MB、`GraphicOverlay`、`MlKitInitProvider`） |
+| 裁剪 | uCrop（`MCropActivity`）— 识别不佳时可手动纠偏后再跑 |
+| 结果 | 匹配卡牌库 → `CardDetailActivity`（详情 / 价格）→ 购物车或上架 |
+
+报告中的扫描流程可概括为：
+
+```
+相机 / 相册 → ML Kit 边框检测 →（可选）手动裁剪 → 匹配卡牌数据库 → 详情页
+```
+
+加固（爱加密）导致无法还原完整 Java/Kotlin 源码，上述链路主要来自 Manifest、Native 库与 Flutter 字符串等静态证据，**不是**可运行的源码级复刻。
+
+本 demo **只复现「拍/选图 → 锁定卡边 → 裁剪纠偏」** 这一段视觉能力，不包含交易、匹配库、登录、支付等平台能力。
+
+---
+
+## 2. Demo 是什么
+
+纯 Flutter 小应用（`carddex_demo` v2.0.0），竖屏暗色 UI。
+
+**一句话**：拍照或相册选图 → 按 TCG 引导框裁切 → ML Kit 目标检测得到外接框 → 经典 CV 细化倾斜四边形 → 透视 / 轴对齐裁剪 → 预览结果。
+
+**明确不做**：
+
+- 实时预览帧上的检测（拍摄页只有引导框）
+- 卡牌身份识别 / 图库检索 / 价格
+- 打包自研或从 APK 抽取的 TFLite 模型（早期方案已废弃）
+- 集换社业务（订单、IM、拍卖、仓储等）
+
+---
+
+## 3. 与集换社扫描链路的对照
+
+| 维度 | 集换社（反编译推断） | 本 Demo |
+|------|----------------------|---------|
+| 形态 | 交易 App 内嵌模块（Native Activity） | 独立 Flutter Demo |
+| 采集 | CameraX + 相册 Activity | `camera` + `image_picker` |
+| 检测时机 | 报告描述含实时预览标注（`GraphicOverlay`） | **仅静帧**：进入预览页后跑一次 |
+| 检测引擎 | Google ML Kit | 同为 Google ML Kit Object Detection |
+| 边框形态 | 报告侧重 AABB + Overlay；细节不可见 | AABB → 可选倾斜四边形细化 |
+| 裁剪纠偏 | uCrop 手动为主 | 自动透视 / 轴对齐裁剪（无手动 uCrop） |
+| 下游 | 匹配卡库 → 详情 / 交易 | **无**：只展示锁定框与裁切图 |
+| 架构上下文 | Native + Flutter Hybrid + 大量 SDK | 单应用、无后端、无加固 |
+
+技术选型上，demo 与集换社扫描模块最接近的一点是：**都用 ML Kit 做卡牌区域定位，而不是卡牌分类识别**。定位成功后，集换社走业务匹配；demo 停在图像几何处理。
+
+早期仓库内的 `carddex_flutter_demo_plan.md` 曾计划复刻 CardDex 的本地 `detect.tflite`；当前实现已改为 ML Kit，与集换社扫描栈更一致，也避免依赖 APK 内模型资产。

+
+## 6. 处理流水线（实现细节）
+
+### 6.1 引导框
+
+TCG 常见比例 **63:88**。框约占视口高度 62%、宽度 78%，垂直中心约在 46%。
+
+- 拍照：用预览视口 + `BoxFit.cover` 反算到照片像素（`GuideFrame.inCoverImage`）。
+- 相册：直接在图像坐标系算引导矩形（`GuideFrame.inImage`）。
+
+进入检测前先按引导框裁掉框外区域，减小背景干扰（隐含前提：卡已大致落在框内）。
+
+### 6.2 ML Kit 检测（`CardDetector`）
+
+- `DetectionMode.single`，开启分类与多目标。
+- 输出 `CardBox`：AABB、置信度、标签（通用 COCO 类名，**不是**卡牌 ID）。
+- `pickBest`：分数 = `0.4 * confidence + 0.6 * fillRatio`，丢弃填充比 ∉ `[0.04, 0.98]` 的框。
+
+这是通用物体检测，不是「宝可梦 / 游戏王」专用模型；能锁边框即可，标签仅作调试信息。
+
+### 6.3 角点细化（`CardCornerRefiner`）
+
+在 AABB 邻域做经典视觉，把轴对齐框尽量收成倾斜四边形：
+
+1. 顶部略抬高、ROI 外扩  
+2. 灰度 → 模糊 → Otsu，保证 AABB 中心为前景  
+3. 最大连通域（优先覆盖种子点）  
+4. 凸包 → 最小面积矩形 → TL→TR→BR→BL  
+5. 面积校验失败则退回 AABB；成功则外扩并照顾卡头区域  
+
+### 6.4 裁剪（`CardCropper`）
+
+| 条件 | 行为 |
+|------|------|
+| 有倾斜四边形 | `copyRectify` 透视变换 → 竖向校正 → 贴合 63:88 |
+| 仅有 AABB | 外扩约 6% 后轴对齐裁切并贴合比例 |
+| 无检测框 | 按引导框中心区域裁切（`usedDetection: false`） |
+
+大图最长边限制约 2560；JPEG 质量约 98。
+
+---
+
+## 7. 能力边界（相对报告中的产品能力）
+
+反编译报告中的集换社扫描落点是 **「识别成功 → 匹配数据库 → 交易」**。本 demo 停在几何裁切：
+
+```
+集换社:  采集 → ML Kit → (uCrop) → 匹配库 → 详情/交易
+本 Demo: 采集 → 引导裁切 → ML Kit → 角点细化 → 自动裁切 → 预览
+                ▲                              ▲
+                多出的本地几何步骤               无业务下游
+```
+
+因此：
+
+- 能验证「静帧 + ML Kit 锁边 + 透视纠偏」是否够用做上架 / 鉴定前处理。
+- **不能**验证卡牌检索准确率、价格、多卡桌面、强反光 / 极端角度等产品级指标。
+- 检测失败时仍可按引导框出图，便于继续调试 UI，但不代表识别成功。
+
+---
+
+## 8. 运行
+
+```bash
+export PATH="$HOME/flutter/bin:$PATH"
+cd /Users/a1518/Desktop/project/card-dex-demo
+flutter pub get
+flutter run
+```
+
+Android `minSdk` 为 26；需相机与媒体读取权限。真机效果明显优于模拟器。

+---
+
+## 10. 小结
+
+本 demo 是对照集换社扫描模块做的 **视觉前处理实验床**：同样依赖 Google ML Kit 做区域定位，但用 Flutter 实现「引导框 → 静帧检测 → 角点细化 → 透视裁切」闭环，刻意剥离交易与图库匹配。若后续要对齐集换社产品路径，需要在裁切结果之上另接卡牌检索 / 版本匹配 API，而不是继续堆叠本仓库内的几何管线。

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
