3-D surface shape restoration for the breaking surface of dynamic process

The breaking surface and dispersing fragments bring some difficulties to the surface restoration of dynamic process including impact or explosion process.Therefore,a novel method of 3-D restoration for the breaking surface of dynamic process based on FTP is proposed.3-D binary masks are built with the information of the cracks of the deformed fringes images,and the 3-D phase maps are unwrapped under the control of the masks.The experiment of the 3-D surface shape restoration of a breaking glass proved the feasibility of this method,and this method provides a new means for thoroughly analyzing the theory of dynamic process such as dispersing fragments,deformation of material,explosion process and deformation in impact.
