Development of Non-contact On-line Automatic Measurement System Based on Machine Vision
Aiming at the problems of low precision and low efficiency in contact measurement methods of batch work-pieces,a non-contact automatic measurement system is developed based on machine vision.By image processing,edge-extracting,image fitting,precise positioning of 2-dimensional manipular,a simultaneous and accurate measurement of multiple parameters for workpieces can be realized.The experimental results show that measurement precision is bet-ter than 3 μm,with repeatability accuracy better than 0.2%and measurement uncertainty 3.5 μm(k=2).
