In this paper, by using the recently developed AVERLOGIC flat panel display monitor controller AL300, we design a portable spying and calibrating apparatus of the cannon barrel which can collect, process and display the measured data and video signal.

• 应用AVERLOGIC公司最新研制的平板显示控制器AL300,实现了便携式火炮测径窥膛仪的火炮直径数据采集、炮膛视频图像转换与显示系统设计。
