Fragment scattering parameter determination method based on image processing technology

Abstract

The invention relates to a fragment scattering parameter determination method based on an image processing technology. The fragment scattering parameter determination method comprises the following steps: establishing a warhead static explosion scene equivalent target plate three-dimensional model; before a warhead explodes, marking each target plate with a serial number; after the warhead explodes, collecting images of a target plate collected one by one through correspondingly-arranged serial numbers to acquire original images of the target plates are obtained; correcting the collected original image of each target plate to obtain a corrected target plate image; carrying out perforation detection on fragments on each correction target plate image, and removing a false target; extractinga two-dimensional coordinate of the central position of the fragment perforation on the correction target plate image, converting the two-dimensional coordinate to an equivalent target plate in the three-dimensional model, and obtaining a three-dimensional coordinate parameter of the central position of the fragment perforation; utilizing the three-dimensional coordinate parameter of the central position of the fragment perforation to calculate the flying parameter of the perforation on the equivalent spherical surface. The fragment perforation can be quickly, accurately and effectively identified, the position of the fragment perforation can be accurately measured, and fragment parameters can be determined.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method for determining fragment scattering parameters based on image processing technology. Background technique [0002] The scattering characteristics of fragments is an important indicator for assessing the power of ammunition, so it is necessary to test the scattering characteristics of fragments after the warhead explodes. Generally, the explosion radius of the warhead is large and the number of fragments is large, so the statistical workload of fragment scattering parameters larger. [0003] The test of the scattering characteristics of the explosive fragments of the warhead is mainly carried out with the equivalent target plate of a rectangular target or a spherical target, and the radius and recovery angle of the target are carried out according to specific requirements. At present, the calculation method of scattering characteristics mainly relies...
