Other Abstract

The invention provides a bar counting method based on machine vision. The method comprises the steps of acquiring end face images of bars, pre-processing the images, calculating the relative displacement of the bars, analyzing a connected area, counting matched bars, determining the positions of steel bar splitting lines, judging whether the primary steel bar splitting result is accurate or not and the like. Pre-processing of the images comprises smoothing, binaryzation and morphological operation; and analysis of the connected area comprises the steps of splitting stuck bars into single bars and then analyzing the information of the single bars using the connected area again. The method based on machine vision technology realizes automatic counting of bars and judgment of the steel bar splitting result, effectively solves the problems of overlapping and crossing of bars, is high in speed and accuracy, small in modification of a production line and easy to maintain, and greatly reduces the manpower cost of enterprises in production.
