【摘要】 针对现代武器观瞄系统显示图像旋转干扰操作手瞄准的问题,提出了一种基于FPGA的消像旋设计方案。该方案根据从平台姿态传感器获得的旋转姿态信息,对显示图像进行反向旋转,从而消除显示图像的旋转,方便操作手瞄准。该方案同时扩展了无极变焦功能,解决了操杆与显示分辨力不一致的问题,提高了武器观瞄系统的瞄准精确度。更多还原

【Abstract】 To tackle with the problem that the rotation of displaying image disturbs the operator in modern weapon aiming system,this article proposes a kind of design for eliminating display rotation of image-watching-aiming-system based on Field Programmable Gate Array(FPGA).This scheme obtains rotation carriage information from the plat roof carriage sensor,rotates the displaying image reversely, eliminates the rotation of displaying image,and conveniences the aiming of operators.This scheme also expands the ability of changeable focus successively,solves the inconsistence of resolution ratio between the displaying and the operational stick,and improves the perfect precision of aiming.更多还原
