The Design And Implementation Of Image Stabilization System In Indirect Aimed Weapon

In recent years, with the changeable international situation, all kinds of terrorism, religious extremism and national separatism etc.have become increasingly active and made endless violence emerge. Facing the increasingly serious security threats, goverments have spent a great deal of human, material and financial resources in the war against terror. Based on the principle of protect themselves against the enemy effectively, a new firearms common says"bend gun", whose scientific name is"indirect aimed shot weapon systems"came into being in such big context, and has got a rapid research and devepment in several countries.By this weapon system of auxiliary unconventional aiming devices, the shooter which is not exposed situations or the naked eye can not look straight into the target could shot with indirect aimed so as to maximize shelter selves and kill enemies.Indirect aimed shot weapon system as an important part of the special equipment directly decided the maneuverability and practicability in actual combat. This paper studies the system sufficiently and proposed the corresponding realization scheme of modules according to various tactics index.With the application of the scheme, the paper completed all system design and implementation of the sub module in a digital image processing development board. This paper adopts the system on programmable chip technique, by which single chip complete the whole system's logical functions with the characteristics of flexible, extendable cutting and upgrade conveniently. The main control chip of the system whose type is EP2C35F484C8 with low cost and high performance is mianly responsible for the system initialization, the transmission of data flow between modules and coordinate plugin IP core orderly, to ensure the real-time of the system, this paper adopts custom IP core in the time-consuming sub module with hardware circuit, and uses the hardware acceleration technology such as custom instructions, C2H etc. in the optimizing of the algorithm.For the auxiliary sub module of the control system,this paper complete the functions mainly by NIOS II softcore processor in software.when the task is arduous and data flow requires more high-speed transmission,we can transplant the uCOSII or uClinux etc which is mature,stability,high efficiency and low cost of embedded operating system or use double softcore processors to realize the parallel-treatment way so as to improve the system further.After the board level test, this system can complete the several sub modules effectively. On the whole, this design can satisfy the demand of the strict performance requirements in actual combat.With the high level of integration, flexible characteristics, high cost performance and upgrade conveniently, therefore it has a high engineering practical value.
