This paper proposes a new idea of detecting meter using image arithmetic- logic operation and
high-precision raster sensor. This method regards the data measured by precision raster as real
value, the data obtained by digital image-processing as measuring value, and achieves the aim of
detecting meter through the compare of above two datum finally. This method utilizes the dynamic
change of meter pointer to complete subtraction processing of image, to realize image segmentation,
and to achieve warp-value of image pointer of border time. This method using the technology of
image segmentation replaces the traditional method which is low accuracy and low repetition caused
by manual operation and ocular reading. Its precision reaches technology index demand according to
the arithmetic of nation detecting rules and experiment indicates it is reliable, high accuracy. The
paper introduces the total scheme of detecting meter, capturing method of image pointer, and also
shows the precision analysis of indicating value error.
