Abstract:
1. A shape measurement system for measuring a three-dimensional shape of an object, comprising: a picture taking part taking a picture of the object; a projecting part applying light having a predetermined pattern onto the object; a rotation component detecting part detecting, based on a gravity direction and an angle around the gravity direction by a sensor, a rotation component of position information specifying a position to take a picture of the object by the picture taking part; a three-dimensional coordinate calculating part calculating a three-dimensional coordinate of each point of the object based on the rotation component and an image taken at the position; and a three-dimensional shape composing part calculating a translation component of the position information, based on at least two of the three-dimensional coordinates for each point of the object calculated by said three-dimensional coordinate calculating part, based on each image obtained from taking a picture of the object, to which the light is applied from at least two different positions, and the rotation component, and expressing said each point, based on the translation component, by a coordinate in a single coordinate system, and to produce a composed image.
