    • A method for reading a meter includes (1) capturing a first image of digits displayed by the meter, (2) roughly locating the digits by correlating the entire first image against symbols, (3) precisely locating the digits by correlating the digits against the symbols, which are now rotated, resized, and repositioned to maximize correlation, (4) determining and storing nominal centers of the digits in a nonvolatile memory. The method further includes (5) capturing a second image of the digits, (6) locating regions of interest in the second image according to the nominal centers, (7) determining vertical positions of full digits (or partial digits) in the regions of interest, (8) aligning symbols (or partial symbols) and the full digits (or the partial digits) according to the vertical position, and (9) correlating the symbol and the full digits (or the partial symbols and the partial digits).
    • 用于读取仪表的方法包括:(1)捕获由仪表显示的数字的第一图像,(2)通过将整个第一图像与符号相关来粗略地定位数字,(3)通过将数字与 符号,现在被旋转,调整大小和重新定位以最大化相关性,(4)确定和存储非易失性存储器中的数字的标称中心。 该方法还包括(5)捕获数字的第二图像,(6)根据标称中心定位第二图像中的感兴趣区域,(7)确定在第二图像的区域中的全数字(或部分数字)的垂直位置 兴趣,(8)根据垂直位置对齐符号(或部分符号)和全数字(或部分数字),以及(9)将符号和全部数字(或部分符号和部分数字)相关联。
