Research on Billet Character Positioning Based on the Projective Invariants
摘要
Abstract
Aiming at the problem of billet location of heavy rail production line ,a kind of character location method based on projective invariant features was proposed .Firstly ,the feature was presented by linear array of billet character ,the definition of the measured value of the projective invariants was put forward on the basis of it ,secondly ,the method of re‐cursive segmentation based on the variance of the largest class of multi-stage filter w as used ,by finding the satisfied con‐dition of the measured value of the projective invariants and the area of billet characters (that is the image region of inter‐est) quickly ,finally ,coordinate positioning was extracted from the image region of interest by projection ,and then com‐pleted the positioning problem of billet characters .Experimental results show that compared with the Mean Shift character positioning method ,this method can more accurately complete the location of characters ,with good stability and accuracy , improves the correct rate of the character positioning .关键词
