Problems solved by technology

[0005] Because the technical scheme of CN201510672905.8 directly obtains the original color image of the end face of the steel bar for image processing, it is limited by the technical defects of the image processing technology, and the counting error is relatively large under the influence of too bright or too dark environment or the corrosion of the steel bar, and it is impossible to mass stable use

Abstract

The invention discloses a handheld steel bar counting instrument. The instrument comprises a line laser emitter, a binocular camera, a gyroscope, a data processing module, a display screen and a manual operation control module, the line laser emitter emits line laser according to a control instruction of the manual operation control module to be projected to the end face of a steel bar, and when the line laser is projected to the end face of the steel bar, contour laser lines of the end face of the steel bar are obtained; the binocular camera acquires a left steel bar end face contour image and a right steel bar end face contour image with contour laser rays, wherein parameters of a left camera and a right camera of the binocular camera are the same; the data processing module analyzes andprocesses the left steel bar end face contour image and the right steel bar end face contour image to obtain steel bar end face contour three-dimensional data; the data processing module obtains a steel bar end face profile diagram and steel bar number information according to the steel bar end face profile three-dimensional data and the corresponding relation; the display screen is used for displaying a rebar end face profile diagram and rebar number information.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a hand-held steel bar counter. Background technique [0002] In the existing technical solutions, the counting method of steel bars is usually manual counting, and counting workers mainly use colored pens of different colors to mark multiple times to distinguish counted and uncounted steel bars. [0003] The existing manual method is time-consuming, labor-intensive, and inefficient, and after a long time of high-intensity work, the human eyes and brain are prone to fatigue, and the counting error will greatly increase. [0004] Chinese patent document CN201510672905.8 discloses a statistical method for the number of steel bars based on computer vision, which obtains the original color image of the cross-section of the measured steel tendon and converts it into a grayscale image, and then converts it into a binary image after enhancement processing, and then uses the bin...
