Research on Flexible Plastic Sleeve Thickness Detection System Based on Binocular Vision
In order to measure the wall thickness of flexible plastic dustproof sleeve with the shape of conical bellows,a measure-ment system based on binocular stereo vision model was established.The system of two industrial digital camera by PLC workpiece and external trigger image acquisition,the acquisition of multiple sets of image after the corresponding preprocessing,feature point extraction method was adopted to realize image matching,using the feature matching algorithm to extract the correspond-ing 3d coordinate specific information,complete flexible plastic shrouds wall thickness detection.The measurement system,the use of flexible pneumatic clamping claw clip artifacts,reduce the flexible deformation of workpiece to the clip,using high preci-sion movement to move the slider to drive workpiece pictures,by controlling the sliding table specific mobile distance and combina-tion of graphical feature extraction method for multiple artifacts after the photo image feature point selection and image match-ing,complete workpiece thickness and high precision detection.The experimental data show that the absolute detection accuracy of the measuring system is within±0.05mm,which is simple and fast,and shortens the equipment adjustment time in the work-piece production.
