Defect inspection system having human-machine interaction function

A defect inspection system, comprising:

• a linear light source, being disposed at a first position for facing a photographing region;
• N number of cameras, being disposed at a second position for facing the photographing region, wherein N is a positive integer;
• a display device;
• a tag reader;
• and a modular electronic device, being coupled to the linear light source, the N number of cameras, the display device, and the tag reader, and comprising a processor, a memory and a human machine interface (HMI), wherein the memory stores an application program, and the processor being coupled to the memory and the human machine interface;
• wherein the application program includes instructions, such that in case the application program is executed, the processor being configured for:
• controlling the linear light source to emit a detection light for irradiating the photographing region during an article being transferred by an article transfer system;
• controlling the N number of cameras to acquire an article image frame from the article in case of there being a segment of the article in the photographing region;
• applying at least one image process to the article image frame, so as to generate an article feature image;
• extracting a plurality of defect features from the article feature image, and then determining whether there are existing any strange defects in the article feature image by matching the plurality of defect features with a plurality of reference defect features;
• stopping at least one motor of the article transfer system from running in case of there being one strange defect detected from the article feature image, so as to make the segment of the article be positioned on a manual inspection region;
• generating a plurality of defect tags correlated to the strange defect, and controlling the display device to display the plurality of defect tags;
• labeling the article feature image so as to produce a labeled example after the tag reader is operated to read a specific defect tag from the plurality of defect tags;
• and restarting the at least one motor to run after receiving a transfer restarting command transmitted by the human machine interface.
