APPARATUS FOR MEASURING STRIP POSITION APPARATUS FOR CONTROLLING STRIP DEVIATION AND METHOD FOR CALCULATING STRIP DEVIATION

摘要

According to an embodiment of the present invention, there is provided an apparatus for measuring a position of a plate, comprising: an image measuring unit for obtaining image information on a strip; And an edge detector for detecting an edge of the plate by performing a pre-filtering process on the image information; The edge detecting unit detects the edge of the plate using the image information obtained by calculating the one-dimensional profile value by combining the preprocessed image information in one direction and weighting the calculated value to improve the plate position measurement accuracy .
