# Coin Scan Demo
|
||
|
||
对照 CoinSnap 反编译：`detect.tflite`（YOLOv5 硬币检测）+ `blur.tflite`（模糊度二分类）。
|
||
|
||
流程对齐 card-dex-demo，但换成硬币圆框与双模型：
|
||
|
||
拍照 / 选图 → **blur 清晰度检测** → **detect 目标框** → **圆形轮廓精修** → 圆形裁剪预览。
|
||
|
||
模型来自 CoinSnap APK `assets/`：
|
||
|
||
| 模型 | 输入 | 输出 |
|
||
|------|------|------|
|
||
| `detect.tflite` | `[1,320,320,3]` NHWC, `/255`, letterbox | `[1,6300,6]` → cx,cy,w,h,obj,cls |
|
||
| `blur.tflite` | `[1,3,224,224]` NCHW, `/255`, 白底 letterbox | `[1,2]` → `[blur, clear]` |
|
||
|
||
## 运行
|
||
|
||
```bash
|
||
export PATH="$HOME/flutter/bin:$PATH"
|
||
cd /Users/a1518/Desktop/project/coin-dex-demo
|
||
flutter pub get
|
||
flutter run
|
||
```
