轻武器电子校瞄系统的算法设计及系统验证

Algorithm Design and System Verification of Electronic Pointing System of Light Weapon

摘要:

轻武器验收的重要指标之一是其击打目标的准确度[1],瞄准系统的精度直接影响武器性能的发挥,而传统的校准设备只能完成武器的粗校准,为此设计了一种新型的轻武器电子校瞄系统；其设计核心是枪口轮廓在图中精准识别算法的构建；在算法构建中,通过引入正六边形搜索窗口和梯度方向信息判据对随机Hough变换算法进行改进,弥补了已有的Hough变换方法计算复杂程度高,占用内存大的不足[2]；在MATLAB中充分验证改进算法的优良效果后,将该算法移植到基于嵌入式软件环境的电子校瞄系统中,系统通过测试表面电子校瞄系统对枪口的中心位置,枪膛中心点和十字光标相对位置,展现出优良的校准性能,初步实现了枪支瞄准系统的精细校准；在整个校准过程中,不直接与轻武器接触,可以避免传统校瞄系统重复安装对枪管造成的磨损,为传统的校准方式提供了一种新方法。

Abstract:

Light weapons acceptance is one of the most important factors, that hit targets on the accuracy, the aiming system accuracy has a direct impact on performance of weapons to play, and the traditional calibration device can only be accomplished with weapons of coarse alignment. So design a new light weapons electronic aiming system. The core of the design is the construction of the accurate recognition algorithm in the figure. In constructing algorithm, through the introduction of regular hexagon search window and gradient direction information criterion to improve the randomized Hough transform algorithm, to make up for the existing Hough transform method for computing complex degree is high, occupies large memory. Fully validated in Matlab excellent effect of improved algorithm, the algorithm was transplanted to the embedded software environment of electronic aiming system, by testing the surface electronic aiming system on the muzzle of the center position and bore center point and cross cursor relative position, showing excellent performance calibration, the initial realization of fine calibration of gun system. In the calibration process, not directly in contact with light weapons can avoid the traditional aiming system repeats the installation on the barrel caused by wear, provides a new method for traditional methods of calibration.
