This paper presents the design and implementation of an automatic inspection system for parts rejection in a manufacturing process, where parts are the short pieces of circle- and square-pipes. The designed model is based on a stereo vision and programmable logic controller (PLC). Both shape classification and height measurement of the parts can be achieved simultaneously with a stereo vision. Its computation is implemented in Raspberry Pi broad, which is supported by Python and OpenCV. The simplified stereo vision is established by two commercially available webcams and it has already been calibrated. If the shape and height of products are not correct, the rejected signal is produced and passes to a PLC. Meanwhile, the PLC of model Siemens S7-1200 is applied to control the pneumatic rejection cylinder. The designed method is completely executed and evaluated. The experimental result shows good synchronization between Raspberry Pi and PLC. The accuracy of shape classification is more than 98% and the error of height measurement is less than ±1mm.
