Embodiment 1

[0060] according to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 with Figure 8 The on-line visual measuring device for the shape of the hot-rolled steel strip end of the assembly cost embodiment is composed of a linear CCD camera 1 on the left and a linear CCD camera 2 on the right to form a binocular vision system, and then the binocular vision system and a laser 3 The scanner of the imaging system is installed above the strip steel production line at an angle of 0 degrees, and the distance between the linear array CCD camera 1 and the linear array CCD camera 2 is 300 mm. The distance from the center line of the scanner of the imaging system to the center line of the reversible rolling mill 5 is 5878 mm. The scanner of the imaging system is installed on the steel structure platform at the exit of the reversible rolling mill 5. An insulating asbestos interlayer is designed under the platform, and steel plate fences are installed around the platform to iso...

Embodiment 2

[0077] Except that the scanner of the imaging system is installed above the strip production line at an angle of 45 degrees, and the distance between the linear CCD camera 1 and the linear CCD camera 2 is 450 mm, the others are the same as in Embodiment 1.

Abstract

The invention provides an on-line vision measurement apparatus for end shapes of hot rolled strip steel and relates to measurement equipment which is characterized by employing an optical method. The on-line vision measurement apparatus comprises: a hot strip steel end shape detection device, a visual information processing system and an on-line detection device monitoring system. The hot strip steel end shape detection device mainly comprises: a vision sensing system, a laser and a computer processing unit. The visual information processing system comprises: a strip width calculating system, a linear array CCD image processing system, a liquid crystal display screen, a keyboard and mouse, a signal processor and an industrial computer. The on-line detection device monitoring system comprises: a monitoring interface for the strip width calculating system and background database management software. The vision sensing system of the hot strip steel end shape detection device is connected with the visual information processing system via a network cable; and the visual information processing system is connected with the on-line detection device monitoring system via a USB wire. Through the on-line vision measurement apparatus, technical problems that in the prior art, strip steel end shape detection speed is slow, efficiency is low and detection precision is not enough are overcome.

Description

Technical field [0001] The technical solution of the present invention relates to a measuring device characterized by adopting an optical method, specifically an online visual measuring device for the end shape of a hot rolled strip. Background technique [0002] Due to the harsh environment of the production site, the traditional strip end shape detection uses offline and manual methods for sampling. The sampling time is long, the labor intensity of the workers is high, and the measurement information cannot correspond to the production status in time, and it cannot reflect the status of the production line in real time. The closed-loop control of production cannot be effectively realized, which reduces the effective operation rate of the rolling mill and increases the scrap rate of strip steel. These have seriously affected the production of strip steel and restricted the further improvement of product quality. Therefore, there is an urgent need to develop a high-precision and...
