Embodiment Construction

[0021] Taking the bundled round steel of Ø60mm as an example to introduce the present invention, in conjunction with the attached Figure 1-2 The present invention is described in detail.

[0022] First build as figure 1 The shown binocular vision system for the end face of bundled round steel includes: a computer 1 installed with an image storage and processing program, a light source 2 , a left camera 3 , a right camera 4 and a calibration plate 5 . The left camera 3 and the right camera 4 are placed side by side horizontally and perpendicular to the end face of the bundled round steel of the measured object. The light source 2 is at the middle position between the left camera 3 and the right camera 4. The camera 3 and the right camera 4 are connected together by a data cable, and placed in a position where the left camera 3 and the right camera 4 are not blocked, and the calibration plate 5 is placed within the depth of field range directly in front of the left camera 3 an...

Abstract

Disclosed are a bundled round steel end face binocular vision system and a spatial positioning and counting method. The system includes a computer (1) equipped with an image storage and processing program, a light source (2), a left camera (3), a right camera (4) and a calibration board (5). The bundled round steel end face spatial positioning and counting method includes the steps of (1) binocular camera calibration; (2) image acquisition by the left and right cameras and epipolar rectification; (3) enhancement processing of left and right images; (4) binarization of the left and right images; (5) circle recognition of the left and right images; (6) round steel counting; (7) solving of the parallax of binocular stereoscopic vision; and (8) solving of three-dimensional coordinates of centers of the round steel end faces. The system is capable of end face center three-dimensional coordinate measurement and counting of bundled round steel, and has a low requirement for the installation precision of the cameras.

Description

technical field [0001] The invention relates to a binocular vision-based method for acquiring and counting spatial coordinates of the end face center of an object, in particular to a binocular vision system for the end face of a bundled round steel and a method for spatial positioning and counting. Background technique [0002] Round steel is the main product of the current steel industry, and it is also an important raw material for production and processing in the industrial field. The quality requirements for round steel in different industries are also different. The specifications of round steel produced in the iron and steel industry are also varied. In order to distinguish different types and specifications of round steel, it is necessary to paste labels on the round steel to facilitate identification of some of the round steel. Basic Information. Buyers can know the diameter, length, production furnace number, composition, production date and other information of th...
