摘要

To solve the problem of extracting and locating the manual circular marks from complex background in the image of range visual measurement, two kinds of extraction methods of circular manual mark were studied, one was the interactive extraction method based on region of interest and the other was the extraction method based on image gray scale and geometric morphology. In this paper, the two methods are introduced at first, and then the methods are adopted to extract the circular marks from the image of visual measurement. The edge extraction and positioning results are compared, and the advantages and disadvantages of the two methods are analyzed. The result shows that the first method can extract the edge of the circular mark smoothly, but this method a lot by the image of the circular marks, while, the second method is less affected by the image of the circular mark. But the edge extracted by the second method is serrated, and part of the circular mark pixels misidentified as background, which is not in conformity with the actual situation.
