principles of the structured light 3-D vision

the process of 3-D measurement consists of applying simple geometry to find the intersection of the camera rays corresponding to the detected features with the appropiate plane of the projected light and is both trivial and error-free the 3-D profile of the object under measurement is obtained with respect to a base plane which acts as a plane with a defined y co -ordinate as shown in figure 2. the z-axis is considered on the projected line and the y-axis is perpendicular to eh plane of x-z.
