An imaging-based detection device for on-line products inspection

The image of product in question is acquired by CMOS image sensor and thus is digitized and transferred to MCU. The quality of the product is evaluated through image processing and analyzed by ARM. In so doing, the defective products are automatically removed by the proposed system, with the inspection results gathered and reported to supervising computer on a daily basis. The system adopts LPC2210 processor featured in ARM7TDMI, along with the imbedded multi-task real-time μC/OS-Ⅱoperating system. The presented system simplifies the development of application software, as well as ensures real-time running and reliability for each task, thus the performance of design is satisfied.
