Title: System and method for focusing discrete points on an under-measured object

Abstract: A method for focusing discrete points on an under-measured object is provided. The method includes: (a) receiving an image of the object, selecting measurement points on the image, and obtaining X, Y coordinate values of the measurement points; (b) searching a solid point on the under-measured object according to the X, Y coordinate value of one of the measurement points, wherein the solid point corresponds to the measuring point; (c) emitting a laser light to the solid point for computing a vertical distance "h" between the laser aid and the solid point; (d) computing a Z coordinate value of the measurement point according to the "h"; repeating step (b) to step (d) until all the Z coordinate values of the measurement points have been computed; and (e) focusing the solid points according to the X, Y and Z coordinate values of the measurement points. A related system is also provided.
