The orbicular image is very familiar in images
progressing. To detecting orbicular images, many parameters
were got by center coordinates. The algorithm of measuring
center position based on digital image processing is proposed
in this paper. First, the basic circle recognition’s algorithm is
analyzed in the same time, for double images, the method of
separation delimiter is analyzed mainly. Last, an integrated
measurement scheme and realization approach with computer
is presented. Simultaneously, based on experimental data, the
application range of all kinds of detecting algorithm is
analyzed, the result show that this method proposed is effective
and universal.
