Abstract
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.
