For the practical application project of vision system in industrial production, the research focus is on the improvement of component re line dimension measurement system and related algorithms, and the inspection object is the key dimension of IC auxiliary product carrier tape .

After the packaging and testing process of the chip is completed, each IC is put into a carrier tape and sealed into a roll, which is then applied to the next stage of PCB welding. Large sized ICs such as CPUs are generally placed in trays. These trays are large in size, and the big brother ICs can be easily placed because of the large gap in the trays pocket.

Some small-sized SMD components, such as resistors, capacitors, inductors and MOS tubes, are placed in carrier tape and packaged in rolls on the industrial packaging.

Generally, the dimensions of these components must be matched accurately, otherwise the roll forming quality of the products in the whole process stage and the application in the next stage will be greatly affected
