    • 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.
