导弹发射车视觉辅助导航定位系统设计

Design of Computer Vision-Aided Navigation and Location System for Missile Launching Vehicle

为缩短导弹发射车占领阵地准备时间,提高对点定位精度,将计算机视觉技术应用到发射车上,研制了一种视觉辅助导航定位系统,能辅助驾驶员快速引导发射车准确对点定位,对提高导弹武器可靠性和整体作战性能具有重要意义;针对导航标尺灰度值较高的特点,吸取了Hough变换检测直线的优点,提出了精确定位导航标尺检测方法;为降低成本,采用高速DSP硬件实现,设计了小型化的嵌入式视觉系统。实验表明,系统运行稳定,操作性强,对点定位精度高。

In order to shorten the preparing time of occupying position and improving the locating accuracy for missile launching vehicle, computer vision is applied to it and a vision-aided navigation and location system is developed, by which the driver can be assisted to steer and locate the vehicle quickly and precisely. It has great significance for improving the reliability and performance of missile weapon system. Combining the characteristic of navigation ruler with higher gray value and the advantage of linear detection through Hough transform, the method to precisely locate the navigation ruler is brought forward, In order to lower the cost, high-speed Digital Signal Processor is emand an embedded mini-system is designed, It＇s proved by experiment that this system is practical and reliable and improves the locating precision.
