指针式仪表识别系统的设计

Design of Recognition System of Analog Measuring Instruments

介绍了基于图像处理技术的表盘识别系统的组成及其识别过程,针对表盘面与镜头面不平行问题,设计了一种景深校平函数,并利用第二最近法则解决了指针误判问题。只要对系统参数稍作修改即可适用于其他类型的仪表。实验表明,该系统具有良好的实用性。

The composing and recognizing process of an analog measuring instrument recognition system is proposed in this paper. The Rectify Function of Depth is designed to solve the question that the meter and the lens are non-parallel. And The Second Closest Principle is thought up to decrease the error. The system can be used in other meters only by changing a little parameter. The＂ practice suggests that it is of good practicability.
