Machine vision automatic tracking control system based on laser source motion

Abstract

The invention discloses a machine vision automatic tracking control system based on laser source motion. The machine vision automatic tracking control system comprises a primary controller, a to-be-measured sample, an image processing system and a laser source automatic tracking system, wherein the primary controller is arranged in a control center, a to-be-measured area A is arranged on the to-be-measured sample; the image processing system comprises a CCD (charge coupled device) image capturing sensor, a first sub controller and an image storage device for storing information which is captured by the CCD image capturing sensor, the image storage device is connected with the first sub controller; the laser source automatic tracking system comprises a reflecting prism, a laser device, a second sub controller and a motion mechanism for driving the laser device to move, wherein the motion mechanism is connected with the second sub controller; laser rays emitted by the laser device are sent out to the reflecting prism, the laser rays are reflected on the reflecting prism and are reflected to the to-be-measured sample to form a labeled zone B. the machine vision automatic tracking control system is simple in structure and can be used for realizing non-contact measuring under a high-temperature environment.

Description

technical field [0001] The invention relates to the technical field of machine vision tracking, in particular to a machine vision automatic tracking control system based on the movement of a laser source. 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 meas...
