    摘要: Measurement of 3D displacement based on successively captured images of an object becomes difficult to be performed due to a load imposed on an operator along with an increase of the number of target portions defined on the object and that of time steps for displacement measurement. A device for displacement measurement executes stereo measurement relative to a stereo image to generate 3D shape information and orthographically projected image of an object for each time, and tracks the 2D image of the target portion through pattern matching between orthographically projected images at successive times to obtain a 2D displacement vector. The device for displacement measurement converts the start point and the end point of the 2D displacement vector into 3D coordinates, using the 3D shape information, to obtain a 3D displacement vector.
