双波段自动枪瞄系统方案设计与实现

Design and Implementation of Dual-Spectral Automatic Gun-Aiming System

摘要: 针对传统枪瞄技术的不足，以图像的数字化处理手段为基础，设计并实现了一种双波段的自动枪瞄系统。首先分析了系统的总体功能、软硬件的设计要求和实现原理，确定了成像模块、控制电路模块和软件系统为主构成系统的总体方案。分别设计了具备大视场和小视场的白光和红外成像系统；并采取图像增强及红外伪彩手段解决了图像对比度不高及灰度图像细节信息不明显等问题。经实际检测验证，该双波段自动枪瞄系统的各项指标均达到系统设计的技术指标要求，能够满足实际需求。

Abstract: Aiming at the shortage of traditional aiming telescope, a dual-spectral automatic gun aiming sys-tem is designed based on digital processing method of image. Firstly, overall function of the sys-tem, requirement of software and hardware and principle of the system are analyzed. Design of the whole system composed of imaging module, control circuit module and software is proposed. Secondly, lens with big and small field for visible spectrum and lens for infrared spectrum are designed for use in the daytime and in the evening. Thirdly, in order to acquire more information from image accurately, image enhancement and pseudo color image are studied. And contrast ratio and details of image are improved. The test results indicate that the indexes of the system match the design function requirements well.
