Machine vision based full-automatic grinding system and full-automatic grinding method

The invention firstly provides a machine vision based full-automatic grinding system. The machine vision based full-automatic grinding system comprises a workpiece clamping platform, a grinding device, a machine vision image system, an upper computer control system and a robot control cabinet. The workpiece clamping platform is used for clamping and locating to-be-ground workpieces. The grinding device comprises an industrial robot mounted on one side of the workpiece clamping platform, and a grinding execution device used for grinding the to-be-ground workpieces is mounted on the industrial robot. The machine vision image system is used for collecting image data of to-be-ground faces of the to-be-ground workpieces. The upper computer control system sets up a three-dimensional model of theto-be-ground faces according to the image data, collected by the machine vision image system, of the to-be-ground faces, and a grinding track of the to-be-ground faces is obtained. The robot controlcabinet receives grinding
