Laser triangulation method steel plate optimized length measuring device

Abstract

The invention relates to the technical field of steel rolling, and particularly discloses a laser triangulation method steel plate optimized length measuring device which comprises a plurality of industrial cameras, a laser and a transmission control system, the industrial cameras are installed on the transmission side of a conveying roller through a support, and the industrial cameras irradiate the center line of the conveying roller. The laser device is provided with a laser transmitter and a laser receiver, the laser transmitter is mounted on the cooling bed side of the conveying roller through a support, and the laser receiver is mounted on the transmission side of the conveying roller through a support and used for irradiating the center line of the conveying roller by the laser device to form laser rays; the displacement of the steel plate is measured through a direct laser triangulation method, the steel plate enters the industrial camera after being scattered by the end part of the steel plate and forms an imaging point on an imaging plane of the industrial camera, the coordinate of the image point and the position of the laser point of the section of the steel plate have a mapping relation, and the end point of an image laser line is searched after image data is collected by a computer; and calculating end part coordinates of the steel plate according to a projection transformation formula, and further calculating the length of the whole steel plate.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a laser triangulation optimized length measuring device for steel plates. Background technique [0002] At present, most of the steel plate length sizing methods used in China are sizing machines, which are very heavy and have a high failure rate. The motor drive is used to control the walking of the mechanical equipment, and the walking distance is calculated by the absolute encoder. Due to the uneven track and other conditions on site, the measurement accuracy is not high, and the length is often inaccurate. [0003] Another way to measure the length of the steel plate is to measure the encoder of the roller, and then convert it into a length through the program. Due to the adverse factors such as vibration and wear on the surface of the roller table in the on-site environment, the measured data after a period of use has a large deviation. production is adversely affecte...

AI Technical Summary

Problems solved by technology

The motor drive is used to control the walking of the mechanical equipment, and the walking distance is calculated by the absolute encoder. Due to the unevenness of the track on site, the measurement accuracy is not high, and the sizing is often inaccurate.

[0003] Another way to measure the length of the steel plate is to measure the encoder of the roller, and then convert it into a length through the program. Due to the adverse factors such as vibration and wear on the surface of the roller table in the on-site environment, the measured data after a period of use has a large deviation. adverse effects on production

Therefore, it is necessary to design a laser triangulation steel plate optimization length measurement device to solve the existing problems of unconfirmed and difficult measurement of steel plates in operation
