Inspection to 3-D deformation of a dynamic object using fringe projection techniques

A projected fringe profilometry (PFP) is a wide optical measurement technology to gauge the three dimensional appearance of object.Because of non-contact type , the short retrieve time and low environmental effect,PFP was usually used in many fields.PFP has become rather efficient and precise on gauging the three dimensional appearance of the static obiect because of its persistent development in recent years.However,it is still not mature yet to gauge the dynamic object. If we could develop a gauging way in the dynamic object , the application would be more widespread.
First of all,using PFP as the gauging principle and utilzing the math algorithm for analyzing the changes between the dynamic measured object and the blurred fringes.Secondly,reconstructed the inspected object's three dimensional appearance and the velocity. Finally,found out the deformation of the measured object.
The technology of this thesis broke through the typical measurement of velocity.We could analyze the velocities of three dimentional dirtions by only single optic imformation.
