Abstract

According to an embodiment, a measuring device includes a projector, an image capturing unit, and a first calculator. The projector projects, onto a target, a first superimposed pattern which is obtained by superimposing a first pattern having a periodic change and a second pattern configured with a first design for specifying a period of the first pattern. The image capturing unit captures the target, onto which the first superimposed pattern is projected to obtain an image. The first calculator performs matching of the first design taken by the image capturing unit, which is included in the first superimposed pattern in the image, with the first design projected by the projecting unit, and calculates correspondence between a second superimposed pattern, which points to the first superimposed pattern captured in the image, and the first superimposed pattern.
