Acquirement Method of Damage Parameter of Bullet Penetrating Gelatin Target
摘要
Abstract
To accurately obtain the parameters of bullet damaging gelatin target,the digital image-processing technology on the basis of improved adaptive mean filter and outline tracking method were put forward to segment contour line of gelatin target.The 3-D modeling technology was used to build 3-D model of damaged cavity,which was based on the methods such as removing pseudo contour-line,polynomial fitting,removing horn according to tangent-line-slope difference and ellipse cross-section method.The penetrated gelatin image shot by the super-speed imaging system was applied to test the method.The three important damage parameters were calculated exactly,including the maximum winking cavity volume,the narrow tract wound length and the transmitted kinetic energy numeric of bullet.The study offers a feasible method to evaluate the damage efficiency of small arm.关键词
