Paper Abstract

In this paper, the three-dimensional measurement technology of structured light is combined with high-speed photography to measure and reconstruct the surface deformation of aluminum alloy target under the condition of light gas gun loading. The test designed a structured light projection system based on the Kohler illumination structure, and adopted a self-developed high-speed photoelectric camera to receive the deformed fringe image. A 100ns magnitude time-resolved three-dimensional surface measurement of the deformation of the target during the process of the light gas gun pushing the projectile into the target plate is realized. By comparing the results of 3D surface reconstruction with numerical simulation results, the reliability of the proposed method for 3D measurement under high speed impact conditions is verified.
