Abstract


Typical fragments average frontal area interpretation system and shells fragments area is mainly used for interpretation . Fragments typical average data consolidated upwind area and fragmentation guns , muzzle velocity fragments can be obtained attenuation coefficient of the power of conventional weapons and ammunition test provides an important test data . Independent direction of this paper icosahedron 16 analog, the spatial attitude of the broken piece to measure its projected area in the 16 different sampling direction , obtained by the data processing of fragments of maximum , minimum and average windward area . 89C51 microcontroller to control DC torque motor is running , and by the absolute measurement of photoelectric rotary encoder rotary table and the rotation angle , grating displacement sensor measures focusing feed amount , thus forming a closed-loop control system . By focusing accuracy , the CCD camera scan imaging, calculated Fragments Fragments obtained , through image processing, the projected value of the measured direction of broken tablets in the average value of the 16 directions area .
