| Abstract: | Based on laser and CCD image system,the inspected technique of puny deflectable angle measurement to object is presented.With the correlation method in digital image processing,optical measurement of tiny displacement is achieved by obtaining the facula movement.The relation between reflective laser displacement and roll-angle is constructed and the experiment of equal intension cantilever beam is given.The result shows that this system has the advantages of simple constitution,real-time on-line measurement,non-contact and high precision.It will be widely used in engineering. |
