光柵尺采集鞋楦數(shù)據(jù)。4shoelastscanmachinecontrolsystemoutlinedLastscannerusingPCasaPC,usingtheobject-orientedlanguageVC+softwaredesign,development,throughtheMotionControlCarddrivesystemandthree-axiscollectionofdatabyscanningdatafiles,foruseinprocessing.PCoperatingasascannerinterface,completedataanalysis,processingandtheimplementationoft
