摘要
根据仪表的结构特点,提出了复杂的指针式仪表的识别方法。对实现其功能的主要方法做了介绍,如阈值迭代二值化、边界跟踪、Hough变换的目标信息的提取、模板匹配。
A method of automatic indication recognition for a point meter by image processing is presented. The principle and step of the automatic indication recognition meter are described. Image analysis and recognition algorithms, such as threshold iterative gray level transformation and Hough transformation, edge-detect, and the template matching method, are used to take out the informanon of the point meter.
