Many large-scale(several meters to dozens of meters)or complex parts and new composite ma-terials are used in atuo,aerospace,shipping,military industry and so on,the rapid and feasible 3D profile,de-formation and strain measurement are in urgent need. In view of the need,a new approach based on close range photogrammetry and digital image correlation is proposed and implemented. In this method,multi-image in 2D sequence are taken by many kinds of industrial cameras,and the 3D coordinates,deformation and strain data of tested objects can be resolved quickly based on these images. Owing to this method,not only rapid measurement on large-scale or complex parts,small to medium parts,micro-nano scale and material property analysis can be realized,but also vabration and shock from low to high velocity and modal analysis can be satisfied. Application results in mechanical engineering,materails science,mechanics and many industries show that,the new method is versatile,rapid,feasible and flexible. Futhermore,remarkable economic and social benefits have been achieved.
