摘    要:高速激光相照系统以双目视觉为基础,利用脉冲激光器作为光源照亮弹丸,使用高速相机进行拍照,获取弹丸在飞行过程中的图像进而获得弹丸运动以及姿态参数。时序控制器是连接相机、脉冲激光器、触发靶等设备的关键部件,主要功能是控制系统各部分之间的时序,同时还有计时功能。时序控制器可根据要求输出相机启动触发信号和多次脉冲激光器闪光信号。在相机快门打开的时间内激光器多次闪光,相机可在一次曝光时间内拍摄多张图像,实现对高速飞行的目标弹丸进行拍照。

关 键 词:高速激光照相; 时序控制; FPGA

Abstract:High speed laser camera system which based on binocular vision using pulse lasers as a light source, and high speed camera to take pictures, access to the projectile in the flight of the image and then get the projectile and attitude parameters. Timing controller is a connected to the camera, pulse laser, trigger the target and other key components of the device. Its main function is to control the timing of the various parts of the system and timing . The timing controller can output the camera start trigger signal and multiple pulsed laser flash signals as required. The camera can flash multiple times during the time the camera shutter is turned on, and the camera can take multiple images in one exposure time to take pictures of the target projectile for high speed flight.
Keywords:high speed laser photography   timing control   FPGA
