英文摘要: Abstract(#br)An on-line dimensional accuracy measurement method was proposed based on machine vision technology to realize the real-time measurement of straightness and roundness of spun workpieces during spinning. An image acquisition system was developed to obtain the real-time images of conical spun workpiece and the camera calibration was conducted. The edges of the conical spun workpiece were extracted by region of interest (ROI) extraction, image deblurring, denoising and edge detection. The straightness and roundness of the spun workpieces were automatically calculated by writing the calculation program. The reliability of on-line dimensional accuracy measurement system was verified by comparing with measurement results of 3D measuring machine. The results show that the...
