Embodiment Construction

[0034] The technical problem to be solved by the present invention is to provide a method and device for rechecking and counting bars, which can quickly and accurately obtain the number of bundled bars, has high precision and fast speed, and can be widely used and popularized.

[0035] The present invention will be further described below in conjunction with drawings and embodiments.

[0036] The invention includes a method and device for rechecking and counting rods. Under the condition of light, an industrial camera collects images of the end faces of rods, uses the method for rechecking and counting rods to segment, identify and count the images, and displays and outputs them through a display screen.

[0037] The example of the present invention provides a bar rechecking and counting method. The end face image of the bundled bar is collected by an industrial camera. The industrial camera of the example of the present invention uses a German basler area array camera, and the...

Abstract

The invention discloses a bar reviewing-counting method and device. Bundled bars can be automatically reviewed and counted by the method and device, and counting can be more precise and faster. The method has the advantages that the technical problem that background interference occurs in the site of end partitioning, feature recognition and removal detection for the bundled bars is solved in terms of image processing, and counting precision is improved; a high-brightness LED light source is used in the reviewing-counting device is used to enhance detection effect, an industrial camera is used to acquire images for the ends of bars, an industrial personal computer is used for smooth-filtering and setting a threshold for binary treatment, corrosion and connected domain treatment, counting and comparative judgment are achieved, counting results are output by a field display, and the device has the advantages of high speed, high adaptability, simplicity and reliability and the like; production efficiency is improved, labor intensity is reduced for workers, and the method and device has great practical value.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for rechecking and counting bars, which are used to automatically support bundled bars and solve the current problems of inaccurate counting and low efficiency. Background technique [0002] In the production of bars, after the bars on the production line are counted to the number of full bundles, they must be automatically bundled and hoisted into the warehouse. Before the sale leaves the factory, the factory's specialized technicians enter the warehouse and check the accuracy of the bundles by point-and-point method. The entire counting process is time-consuming, inefficient, and labor-intensive. Therefore, based on the consideration of reducing the labor intensity of workers and improving the productivity and production benefits of the rolling mill, the research and development of an efficient and high-precision bar rechecking and counting system has become...
