在靶场光电测量任务中，为满足远距离实时监测任务进展的需求，常要将数字相机采集的图像信号转换为SDI视频信号，并将相应信息叠加后显示输出。针对这一问题，以Microsoft Visual Stdio 2010为软件开发平台，结合OpenCV2.4.11，利用Decklink Duo采集卡将Camera Link Full图像视频信号转换为双通道SDI信号输出，并分别对这些信号进行了文字信息叠加显示处理以及模拟红外伪彩色处理。实验达到了预期的显示效果，证明该方法有效，可以满足实际任务的要求。

To meet the need of long range real-time monitoring in the opto-electronic measurement of shooting ranges, the image signals collected by a digital camera usually need to be converted into the video signals of Serial Digital Interface (SDI) and overlapped with the corresponding information for displaying. To solve this problem, a Decklink Duo acquiring card is used to convert the video signals in Camera Link Full mode into the dual channel SDI output signals by means of Microsoft Visual Stdio 2010 and OpenCV2.4.11. Then, the output signals are processed by character information overlapping and infrared pseudo-color simulation. In the experiment, the expected displaying effectiveness is achieved. It shows that this method is effectiveand can meet the requirements of practical tasks.
