THE ALGORITHM OF CALIBRATION GRID MARKER PROJECTION IDENTIFICATION AND COORDINATES DATA EXTRACTION
摘要
Abstract
Aiming at the problem that it is difficult to identify and extract the marker on calibration grid, the paper proposed a method of identifying and extracting the marker projection according to the characteristics of the calibration grid its own. Firstly, the method removes the background colour and uses Otsu algorithm to segment the image. Then the morphology dilation and erosion operation are used to deal with the segmented image. Finally, the intersect coordinates of every cross grid are identified and extracted from the last step result. The centre coordinates of every domain are calculated according lo the intersect coordinates. Experiment demonstrated that the proposed method can effectively identify and extract the intersect coordinates of calibration grid image.关键词
