The invention relates to a bar on-line automatic counting method based on modified gradient Hough circle transformation. The method includes that after threshold parameters of normal radii, minimum radii, maximum radii and combined radii of bars in various specifications are determined, each frame of real-timely collected bar end surface patterns is processed by the following steps of firstly, reinforcing a current frame of bar end surface patterns on the basis of a modified gradient Hough circle transformation method, subjecting the current frame of bar end surface patterns to Regional Max detection and distance detection according to the corresponding threshold parameters, determining an actual observation central point of a current frame of bar end surfaces, and finally, establishing a relevance matching pair relationship between the actual observation central point of the current frame of bar end surfaces and an actual observation central point of a prior frame of bar end surfaces according to horizontal motion speeds of the bars, wherein in each relevance matching pair relationship, if the actual observation central point of the current frame and the actual observation central point of the prior frame are distributed on the left side and the right side of a bar counting central datum line respectively, a counting variable is added by one, and otherwise, the counting variable is reduced by one. The bar on-line automatic counting method has the advantages of being high in real-time performance, high in counting accuracy and capable of bidirectional counting.
