Abstract
A three-dimensional measurement system includes a projector, an image sensor, an image analyzing module and a measurement module. The projector provides a structured light pattern. The image sensor captures an object image of an object on which the structured light pattern is projected. The image analyzing module analyzes the object image to obtain a space coding image and a phase coding image according to gray level distribution of the object image. The measurement module calculates phase information of each of coordinate points in the phase coding image, calculates compensation information of a coordinate position, corresponding to a coordinate position of a point of discontinuity, in the space coding image, compensates the phase information of the point of discontinuity in the phase coding image by the compensation information, and calculates height information of the object according to the phase information of each of the coordinate points.
