Ruler.im

Ruler.im 可帮助您测量现实世界的物品，例如鞋码或身体尺寸。它还可以让您将在线图像缩放到实际的厘米或英寸，从而轻松准备打印或 3D 建模。Think of it as a calibrated digital canvas that restores objects to their true-to-life size on your screen, serving as a "what you see is what you get" tool for better communication.

几年前，当一位同学问我是否有卷尺时，我本能地递出了充电线并查看了它的长度。那个顿悟时刻激发了 Ruler.im 的愿景。如今，作为一名人工智能产品经理，我正在利用人工智能来构建它，以将这个简单的想法变为现实。

With a suite of tools including coordinate rulers, center-find tools, circular scales, tape measures, and protractors—all with built-in distance tracking—Ruler.im is more than just a utility;这是一个直观的学习工具。
