| description | To solve the problem of the damage effect of static detonation test fragments on target, a photogrammetric technique is proposed to obtain the images of the equivalent target plate before and after the static detonation based on the static detonation test fragments acting on equivalent target plate. For the weak texture of the target plate and the difficulty to measure of the warhead detonation center, their shape feature is represented with single point mark, the salience regions are extracted and tracking matched for the sequence image, the image is absolute localized based on SFM and PnP, then the 3D point cloud of the detonation field shape is reconstructed based on the triangulation method. For the similar of the target plate, it is difficult to identify before and after detonation, the code mark is utilized for the equivalent target plate, the invariance of the cross ratio with the affine transformation is used to decode, and a back-projection localization model of the fragment perforation on the equivalent target plate after the static detonation was established. Finally, The fragment dispersion parameters are obtained, and a complete fragment measurement system is constructed. Through calculation and experimental analysis that the method has higher accuracy and automation for fragments dispersion parameters calculation. Meantime, it is not sensitive to the target plate color and layout, and suitable for complex environments of static detonation test, which can provide accurate and complete data support for the development, improvement and product identification of high-energy and high-efficiency munitions, and provide fragments spatial distribution for the precision strike of new weapons and equipment, therefore, it is beneficial for evaluating the performance parameters of the warhead and target damage efficiency. |
