摘要
为了实现对传送带上的仪器的表面裂纹检测,研究并设计了一种基于Cotex-M4内核的实时图像采集系统。该系统由STM32F407VET6单片机、CMOS图像传感器OV2640以及以太网收发芯片LAN8720A构成。STM32单片机持续地将OV2640采集到的图像显示在LCD上面,并通过以太网将图像数据传输到PC机,PC机实时显示收到的图像,并储存起来供图像表面裂纹分析。实验结果表明:该系统可得到较清晰的图像,网络传输过程稳定,并能够实时地在PC机上面显示采集到的仪器图像,为仪器裂纹检测提供了一种解决方案。
A real-time image acquisition system based on Cotex-M4 kernel is researched and designed in order to detect the surface crack of the instrument on the conveyor belt.The system is composed of STM32F407VET6 MCU, CMOS image sensor OV2640 and Ethernet transceiver chip LAN8720A. STM32 MCU continuouslydisplays the imagescollected by OV2640 , and transmits image data to the PC through Ethernet, then the PC would display the image immediately and store the image data for the analysis of surface cracks.Experimental results show that the system can get a clear image , and the transmission process of network is stable, also the PC can display the collected imagein real time, which it provides a solution for crack detection of instrument.
