摘　　要：基于图像的燃气表远程直读系统设计了在燃气表上加装图像采集模块,通过GPRS方式将图像定时发送到远端服务器,由服务器通过图像处理和模式识别技术对燃气表的读数进行识别。在图像采集模块中,采用了分块迭代算法对图像进行二值化处理,使其具有更好的适应性,并在远程发送前对图像数据进行压缩,以减少数据量。服务器端通过对图像进行二次处理、图像分割等预处理后,采用模板匹配算法对字符进行识别。A new remote direct reading gas meter system is designed .In the system ,an image acquisition module is equipped on the gas meter .The meter image is collected and sent to a remote server by GPRS .The gas reading is read out on the server through image processing and pattern recognition technology .In the image acquisition module ,the block iterative algorithm is adopted for image binarization processing .This makes it have better adaptability and the influence of the environment is reduced .The image data are compressed before remote transmission .In the server ,the meter characters are recognized through secondary image processing ,digital image segmentation and template matching algorithm .
