Abstract


In recent years, with the changing international situation, the three forces of all kinds of terrorism, religious extremism and ethnic separatism has become increasingly active, and endless violence. The face of growing security threats, governments have invested a lot of manpower, material and financial resources in the fight against terrorism. Based on effective against the enemy, and the effective protection of the guiding principles of self, a commonly known as \and development. With the installation of the kinds of weapons systems auxiliary unconventional sights combatants can be completely hidden to the naked eye can not look directly at the target indirect fire, which effectively improves the shooter's ability to grasp the fighter, is also very good to protect themselves, the purpose of killing the enemy. Indirect Aimed Shot image stabilization system as an important part of the special weapons and equipment, directly determines its operability and stability in actual combat, practicality. This paper the image stabilization system to fully study the design according to various technical and tactical indicators. Application of the program, the development of a digital image processing board completed the Design and Implementation of the system of various sub-module, which is to ensure the design of the system is flexible, scalable cropping, a convenient upgrade the features, this paper uses a programmable system on chip (SOPC ) technology, the completion of the entire system from a single-chip logic functions. EP2C35F484C8, low-cost, high-performance FPGA system's main control chip production Altera Corporation, responsible for the completion of the entire system initialization settings work to control the transmission of the data flow between the sub-modules and orderly coordination of various plug-IP core tasks processes, as well as to ensure the real-time requirements of the system, the paper of the time-consuming sub-module in the form of a hardware circuit implementation, and algorithm optimization process, the use of a custom instruction, C2H hardware acceleration technology. Auxiliary control sub-module system, this paper is to use NIOS II soft-core processor in the form of software to complete the module function under heavy control tasks, data flow requirements of the more high-speed transmission in the future, can be transplanted uCOSII uCLinux mature and stable, high-efficiency, low-cost embedded operating system is the use of dual NIOS II soft-core implementation of parallel processing to improve the system further escalation. Board-level testing, the indirect aim and shoot weapons image stabilization system is able to effectively complete each planning sub-module, the overall design to meet the stringent performance requirements of the firearms in actual combat. High integration and the use of flexible features, plus a low-cost, easy to upgrade, it high engineering practical value.
