摘要
该系统通过CMOS图像传感器采集产品的图像信息并转化成数字信号传输到存储器中,由ARM处理器进行图像处理和分析,判断产品是否合格,然后自动剔除不合格的产品。同时,还可以统计每天的检测结果,上传到上位机。系统使用以ARM7TDMI为核心的LPC2210处理器,配合嵌入式多任务实时操作系统μC/OS-Ⅱ。这样既方便了应用程序的开发,也同时保证了各个任务的实时性和可靠性,实现了系统的设计要求。
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.
