The cost and speed of defect detection system are directly affected by the large amount of data.Aim to solve this problem,real-time detection technology of image defects was studied.Firstly,according to the materials characteristic of containing few defects,an image compression method is studied.Then,a data packaging method is designed by using the image compression method.Calculations prove that the maximum data compression ratio of this package format can be up to 2 560.0.Field programmable gate array(FPG...
