摘要

    摘要
  • 摘要: 在兵器靶场测试中，为了获得不同位置弹丸炸点同一时刻的图像，需要将多台异地测量站放置的摄像机同步采集图像数据，提出了图像数据异地同步采集方案，采用GPS技术设计了一种高精度时统系统。该系统采用GPS授时，由时统控制电路和计数器电路实现本地时钟功能，记录每个测量站摄像机起拍时间，从而实现图像数据采集的异地同步，同步精度可以达到微秒级。
    Abstract: In the test of proving ground, in order to obtain the images of projectiles exploding at the same time in different places, multiple cameras at testing stations in different places were controlled to achieve the synchronous acquisition of the image data. This paper presented a method for synchronous acquisition of image and a design of high precision timing system based on global position system (GPS) technology. This system used the GPS timing signal, realized the local clock through a uniform time circuit and a counter circuit, and could record the starting shooting time of the camera at each station to achieve the synchronous acquisition of the image data. The synchronous precision of the system could be microsecond level.
