摘要
Abstract
In order to meet requirements of automation and real-time of water gauge for measuring water levels, the article proposes research and technical methods of automatically extract water gauge water level image information by image processing technology . First it locates the water gauge by the disposes of image enhancement, binarization, edge detection and removal process noise for the water gauge image. Then it realizes character segmentation based on the characteristics of the characters on the water gauge, achieves character recognition using the template matching method, and uses the longest and other arithmetic method to optimize recognition results. Finally, it calculates water gauge readings based on the recognition results at the different situations. Experimental results show that the correctness and accuracy of the method for identifying information is higher. It may meet the actual application requirements.关键词
