Abstract：Inrecentyears，withthedevelopmentofcommercialspaceflight，therequirementsof theproductionqualityfor startracker incommercialsatelitebecome higherandhigher.Inthispaper，“SevenParameter ImageQuantitative Evaluation Standard"is developed，which makesuseof the massive starimage dataaccumulated inthe productionofstar trackerand throughdata modeling theoryresearch.Theadjustmentofoptical machinefor Pistar trackerusethisstandard，andthe final measurementaccuracyof theproductforPistartracker wasverifiedbystargazing test，which prove thestandard is efectively and can improve the consistency of measurement accuracy of the product for Pi star tracker.
