Automatic tracking control system of visual laser marker of machine

Abstract

The invention discloses an automatic tracking control system of a visual laser marker of a machine. The automatic tracking control system comprises a to-be-detected test sample, an image processing system and an automatic laser marker tracking system, wherein the to-be-detected test sample is provided with a to-be-detected area A, the image processing system comprises a CCD image collection sensor, an image storage device and a first controller, the CCD image sensor is connected with the image storage device, and the image storage device is connected with the first controller; the automatic laser marker tracking system comprises a second controller, a servo motor, a reflecting prism, a laser and an incidence graticle, the second controller is connected with the servo motor, the laser light transmitted by the laser runs through light transmission holes in the graticle to radiate the polygonal cylindrical prism, the laser light is reflected by the polygonal cylindrical prism onto the to-be-detected test sample to form a marker area B. The automatic tracking control system is simple in structure, the non-contact measurement in a high temperature environment can be realized, and the problem that the performance of the material from an ultra-large strain range to the breaking cannot be measured by the contact measurement way can be solved.

Description

technical field [0001] The invention relates to the technical field of machine vision tracking, in particular to a machine vision laser marking automatic tracking control system. Background technique [0002] With the progress and development of modern society, the types of engineering materials are increasingly rich and their application fields are also expanding. In order to quickly and accurately measure the mechanical properties and other parameters of materials in production and scientific research, higher requirements are put forward for the performance of material testing instruments. Stress and strain measurement is one of the most basic links in the detection of physical properties of materials. Usually, a professional measurement tool-extensometer is used to measure the lateral and longitudinal deformation of the specimen while applying a load. The methods can be divided into two categories, namely contact measurement and non-contact measurement. [0003] In cont...
