In the industrial field, in order to achieve rapid and accurate detection, sorting, recording irregular objects's products, it is necessary to be able to quickly and accurately measuring the size of the irregular body's area, which is to enhance economic benefits, it is a very important significance. Based on digital image processing of the irregular body projection area measurement, combination of a variety of irregular body area measurement, and on this basis,increasing image processing technology. So that detected in the image more accurate, the error is smaller, more intelligent. This the first time, the projected area of an irregular body of measurement techniques used in windward area of fragments measurement. The use of the projected area of an irregular body measurements can accurately measure the area of windward area of fragments.Through obtain the windward area of fragments,muzzle velocity and bullet fragments available attenuation coefficient,for improving the structural design and improving the projectile lethality projectiles, it has a great significance. |
