基于航空照相枪的数字暗盒设计

航空照相枪是一种安装在歼击机上的小型电影摄影机。传统照相枪主要存在判读环境受限制、判读准确度低、工作可靠性差、效率低等问题。设计了由百万像素CMOS图像传感器、大容量闪存FLASH和CPLD为主要部件组成的数字暗盒。使用基于CPLD状态机设计技术,4片闪存分时存储数据,实现无缓存无压缩实时存储,可以有效地提高判读效率、准确度问题,并使计算机自动判读成为可能。

Design of Digital Cassette Based on Aerial Gun Camera

Aerial gun camera is a kind of small cine-camera installed on the fighter aircraft.There are some disadvantages of gun camera,such as limited interpretation environment,low interpretation accuracy,low reliability and low efficiency.A digital cassette system is designed which is composed of CMOS imaging sensor with mega-pixel,high capacity FLASH and CPLD for engineering embedded equipments.The key technique based on the state machine design of CPLD is used to solve the problem of image collecting and storage.4 pieces of FLASH stored data time-shared without buffer and compression.That will improve interpretation efficiency,accuracy,training quality effectively and make automatic interpretation available.
