用照片测量戒指尺寸
— 获取你的 US / EU / UK / 毫米 尺寸。
用 AI 从照片测量戒指尺寸 — 无需戒指量圈、无需棉线、无需去珠宝店。上传一张手部照片,AI 会根据手指比例估算你的尺寸(US、EU、UK 和内径毫米)。非常适合惊喜求婚、网购戒指以及购买前核对尺寸。30 秒就知道该订哪个尺寸。
照片测量戒指尺寸的原理
AI 分析你的手部照片 — 无名指根部宽度、关节宽度和整体手部比例 — 并换算成标准尺寸(US 5–10、EU 49–63、UK J–T)以及内径(毫米)。它使用你真实的手指而非模特,因此估算贴合你的解剖结构。当你想在不询问对方的情况下网购戒指、计划惊喜求婚或在改圈前核对尺寸时非常实用。尺寸在解锁后显示,因此在你决定之前惊喜得以保留。
用照片测量戒指尺寸的步骤
- 在光线良好处把手平放,手指略微分开
- 正面拍摄手部照片(掌心朝下),无名指清晰可见
- 选择一枚参考戒指,让 AI 知道放置位置
- AI 估算你的尺寸 — US、EU、UK 和内径毫米
- 放心下单,或把估算结果带给珠宝师做最终确认
照片测量最有用的场景
惊喜求婚
从对方手部照片估算尺寸 — 无需尴尬询问,也无需偷偷借戒指。
网购戒指
大多数网购失败都因尺寸。下单前先估算,避免退货改圈的循环。
家里没有量圈
无需打印量纸或棉线加尺子的技巧。一张照片就能得到可用的 US/EU/UK 估算。
赠送戒指
生日或纪念日 — 购买前从照片悄悄核对尺寸。
改圈决定
不确定戒指偏大还是偏小?在付费改圈前先估算目标尺寸。
照片估算无法取代的事
珠宝师的最终测量
估算精度约为 1 个尺寸。要精确贴合(尤其是婚戒),请用珠宝师的戒指棒确认。
关节与根部差异
若关节比根部宽很多,舒适尺寸可能不同。拿不准时选稍大一号。
温度 / 时段
手指遇热膨胀、遇冷收缩。在正常温度下测量结果最可靠。
别再靠猜测决定尺寸
棉线、尺子和猜测是网购尺寸出错的主因。用照片 30 秒测量,一次就订对尺寸。
