A kind of aviation instrument automatic interpretation system based on image process is designed,and the modular design of the system is completed. For the different instruments such as the course pointer, wireless pointer and channel pointer different image processing algorithm algorithm was applied. Then in order to get the course pointer angle accurately, hough transform algorithm was improved. At the same time software system was de signed. Experimental results show that the system can interpret aviation instrument accurately and automatically,and can be applied in practical production.%设计了基于图像处理的航空仪表自动判读系统,完成了系统模块化设计,针对仪表中不同的指针如航向指针、无线电指针、偏流指针和航道杆,设计了不同的图像处理算法,提出了一种基于Hough变换来检测多条平行直线的算法.同时完成了软件系统的设计实现.实验结果表明,该系统可以有效地提高航空仪表检测精度,同时可以有效降低个人劳动强度.
