Abstract

The invention provides bar counting method and device, wherein the method comprises the following steps of obtaining quantity of bar end faces in a current frame image, and marking the bar end faces in the current frame image; obtaining moving speed of bars on a transmission chain; obtaining a position in the next frame image of the last bar end face in the current frame image according to the moving speed of the bars; obtaining the quantity of bar end faces not marked in the next frame image according to the position in the next frame image of the last bar end face in the current frame image; accumulating the quantity of the bars and marking unmarked bar end faces according to the quantity of the bar end faces in the current frame image and the quantity of the unmarked bar end faces in the next frame image; and marking bar end faces reaching preset values in the frame images with a parting line when the accumulated quantity of bars reaches the preset value so as to show that the quantity of bars before the parting line reaches the preset value. By the invention, bars can be accurately counted.

Description

technical field [0001] The invention relates to the field of computer image recognition, in particular to a rod counting method and device. Background technique [0002] When the rod products are delivered to the user, according to the current international standards, it is required to carry out standardized bundling and packaging according to the specified count, that is, to deliver the product with theoretical quality, which is also the common demand of the manufacturer and the final customer, which requires rods Material manufacturers must achieve accurate counting to reduce trade disputes. Due to the harsh conditions at the bar production site, the bars will overlap and cross each other, and there will be many uncertainties in the process of steel separation. Therefore, it is difficult to achieve accurate counting of bar products. [0003] At present, my country's steel mills mainly use two methods of manual counting and photoelectric detection in bar counting, and most...
