Abstract

The invention discloses a fragment field multi-parameter test and three-dimensional reconstruction method and system. The method comprises the following steps: S1, arranging a flash target array and a high-speed camera; s2, the warhead is triggered to conduct static explosion, in the whole process from the beginning of the explosion to the end of the explosion, the high-speed camera continuously shoots perforation optical sequence images of the fragments penetrating through the corresponding flash targets, and shot image data are stored; s3, according to the perforation optical sequence images of the fragments penetrating through the corresponding flash targets, fragment parameters and space coordinates of all the perforations are obtained; and S4, performing fragment field three-dimensional scene reconstruction according to the fragment parameters and the space coordinates of the perforations. By adopting the technical scheme of the invention, the technical problems of limited test range, incomplete acquisition of multiple parameters of fragments, low test precision and incapability of realizing three-dimensional replay of the fragment field in the existing fragment field test method in the static explosion test of the explosion-killing warhead are solved.
