展示HN：Omi – 一款快速的宝可梦卡片扫描器
嗨，HN，
我开发了 Omi——一种简单的方法，可以用手机扫描宝可梦卡片并立即获取结果：名称、系列和当前市场价格。
我之所以制作这个，是因为管理收藏品实在太麻烦了。手动在 TCGPlayer 或 eBay 上输入卡片名称耗时太长，而现有的应用程序要么反应慢，要么使用不便。
Omi 使用设备上的图像识别技术，并在数千张宝可梦卡片图像上进行了轻量级模型的微调。它具备以下功能：
- 卡片检测——即使在光线不均或卡片稍微倾斜的情况下也能识别
- 实时查询——与大约 15,000 张卡片的数据库进行低延迟匹配
- 定价——从多个市场实时获取价格
最困难的部分是确保对不同系列中几乎相同的卡片（比如皮卡丘变种）的高准确率。我最终添加了边缘检测和系列符号识别作为第二次处理，这大大减少了错误匹配。
你可以在这里试用：<a href="https://tcgscanneromi.com" rel="nofollow">https://tcgscanneromi.com</a>。
非常希望能收到反馈——特别是关于速度、对不常见卡片的准确性以及功能建议（批量扫描？卡组跟踪？）。

Hi HN,
I built Omi — a simple way to scan Pokémon cards with your phone and get instant results: name, set, and current market price.
I made this because managing a collection was a pain. Manually typing card names into TCGPlayer or eBay takes forever, and existing apps were either slow or clunky.
Omi uses on-device image recognition and a lightweight model fine-tuned on thousands of Pokémon card images. It does:
Card detection — even with uneven lighting or slightly rotated cards
Real-time lookup — low-latency match against a database of ~15k cards
Pricing — live price pulls from multiple marketplaces
The hardest part was getting good accuracy with cards that look nearly identical across different sets (hello, Pikachu variants). I ended up adding edge detection + set symbol recognition as a second pass, which massively reduced false matches.

Would love feedback — especially around speed, accuracy on unusual cards, and ideas for features (bulk scanning? deck tracking?).
