一种新型的视频十字光标叠加技术

摘要

视频叠加技术在现代在军事领域的应用越来越广泛. 激光校轴、电视瞄准、激光能量检测等都需要用到视频叠加技术. 随着该技术应用越来越频繁, 对其各方面功能要求不断提高. 本文介绍了一种基于Xilinx的CPLD芯片XC95108的视频十字光标叠加技术. 介绍了视频十字光标叠加的基本原理,详细讨论了软、硬件设计,给出了视频十字光标叠加的实验结果. 本技术具有很大的灵活性和多样性,不仅能叠加十字光标,对叠加简单汉字、字符等都可以实现. 本设计具有方法简单、功能强大、可靠性强等优点.%Video superimposition technology has found an increasingly wide utilization in modern military fields, which are used in laser axis adjust, TV targeting, laser energy detect. With the frequently used of technology utilization, the function demand for it is increased dramatically. This paper proposes a novel video cross cursor superimposition technology based on CPLD chip XC95108 from Xilinx. First, the principal of video cross cursor superimposition is introduced;then, the hardware and software design is detailed discussed; finally, the experiment result is shown. The technology is full of flexibility and diversity, not only used for cross cursor superimposition but also for the Chinese characters and other characters. The design has the advantage of simple, powerful and reliable.
