介绍由CCD摄象机和微机图象自动处理系统组成的指针式压力表自动判读系统的构成、计算原理及其处理软件。该系统曾对6台压力表进行表盘自动判读,系统误差不超过±0.12％,对于其它指针式仪表的示值判断具有参考价值。
Introduced by the CCD camera and computer image processing system consisting of automatic pointer pressure gauge automatic interpretation of the composition, calculation principle and processing software. The system had six pressure gauges automatic dial reading, the system error does not exceed ± 0.12%, for other indicators of the indicator has a reference value.
