Abstract

The invention discloses a system and method for adjusting a position and an angle of an optical fiber based on machine vision. The system comprises an industrial personal computer, an optical platformand a CCD industrial camera; the CCD industrial camera is mounted on the portal frame; the portal frame is mounted on the optical platform; two support columns are fixed on the optical platform; electric translation tables are respectively fixed on the two supporting columns; the axial leads of the electric shafts of the two electric translation tables are parallel; optical fiber clamps for clamping optical fibers are respectively supported on the two electric translation tables; two ends of the optical fiber are respectively clamped on the two optical fiber clamps; the industrial personal computer shoots the current position of the optical fiber by using an industrial camera, calculates the deviation distance between the current position and the target position and controls the electrictranslation platform to move, adjusts the optical fiber to a target position, detects feedback deviation of the optical fiber in real time for repeated fine adjustment, and controls a deviation valuewithin a precision range, According to the method, the optical fiber can be automatically adjusted to the target position of the CCD shooting area, the requirement for adjusting precision is met, andfull-automatic adjustment is achieved.

Description

technical field [0001] The invention relates to the field of optical fiber adjustment, in particular to a system and method for adjusting the position and angle of an optical fiber based on machine vision. Background technique [0002] The existing optical fiber adjustment equipment uses a camera to capture and amplify the optical fiber image, and manually adjusts the optical fiber clamp so that the optical fiber is in a horizontal and central position in human vision. [0003] However, this method mainly uses the naked eye to identify the position, the adjustment accuracy is poor, there is no feedback mechanism, the adjusted position is uncontrollable, and the production efficiency is not high. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art, and provide a system and method for adjusting the position and angle of the optical fiber based on machine vision, which can automatically adjust the center position...
