Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] Such as figure 1 As shown, a method for identifying and counting bundled bars comprises the following steps:

[0047] 1) Use the smart mobile terminal to collect the cross-sectional images at the ends of the bundled bars to be counted;

[0048] 2) Use the touch screen of the mobile terminal to delineate the boundary range of the bundled bars to be identified; wherein, the boundary range to be identified is a closed boundary; the principle of delineating the boundary range to be identified is: in addition to the bundled remove the interference;

[0049] 3) Carry out graphic recognition and count the end faces of th...

Abstract

The invention discloses a method and a device for identifying and counting number of rods in a bundle. The method comprises the following steps of acquiring an end face image at an end of the to-be-counted rods in the bundle by means of an intelligent mobile terminal; defining a to-be-identified boundary range of the rods in the bundle by means of the touch screen of the mobile terminal; performing pattern identification on the end surfaces of the rods in the to-be-identified boundary range and counting the end surfaces of the rods; and according to abnormalities which comprise recessions and black heads in the rods in the bundle and indication of each rod end surface which is identified by an image identification engine, increasing or reducing the counted number of the rods, thereby obtaining a final counting result. The method according to the invention has advantages of high convenience, high speed, high rod identification rate, easy carrying of equipment used in the method, easy operation by a worker without complicated training, and high suitability of a material manager in a building construction site.

Description

technical field [0001] The invention relates to image recognition technology, in particular to a method and device for recognizing and counting bundled bars. Background technique [0002] Steel rolling enterprises generally adopt the negative tolerance rolling method, and the bars they produce are sold in fixed counts and bundles according to theoretical weight, while bars such as steel bars and steel pipes are important building materials used by construction companies on construction sites. Accurate counting of bars is very important to construction companies due to the frequent entry of large quantities of bar material. [0003] In current construction projects, the material staff of construction enterprises mainly use the counting method of manual pointing when signing for the steel bars entering the site. This method is labor-intensive and there is no valid record certificate after counting errors. Bar counting methods available at building construction sites. [0004...
