Study On Image Capture System Based On Goal Coordinate Locating System

This topic originates from some defense project sub-item: Goal coordinate locating (survey node) system. The goal coordinate cryoscope, equipped with the monitor and the imagery processing computer, is an incorporate target tracking equipment with multi-purpose of the collection glimmer, the white light CCD television photograph and the laser ranging. Its pattern recognition and taking the difference technology, can help the operator continuously get the accurate target data through the summary aiming, The system has the good combat reaction capacity and certain night fighting ability to the minimum altitude fast goal.This article mainly discuss the analysis and the design for the image capture system– video capture and playback system's. This system is designed with the PC/104 module, including image gathering and processing module and the video capture and playback module. This article in analyzes two big modular structures and in the function foundation, uses the structurization and the object-oriented theory and the method, carries on the system software project work.Main jobs:i. Has analyzed image gathering and the processing module structure and the function, has completed SAA7111 the EVIP driver design.ii. Has analyzed 69000 graph accelerator card hardware support video frequency capture and the playbacking function, has completed the image capture and the playbacking module complete software design.iii. Introduced the image capture and the playbacking subsystem's on goal coordinate cryoscope application.This topic involves the aspect of knowledge, not only requests to system's hardware to be very familiar, including video frequency processor, graph accelerator card and knowledge and so on PC/104 architecture, moreover is also very high to the software request. In the software design, used the method which SP (Structured Programming structurization programming) and OOP (Object-Oriented Programming object-oriented programming) unified to carry on the system planning. Moreover, for the transmission of data, the sub-program compiled alone with the assembly language is transferred in the C language to satisfy the system's timely request well.
