基于FPGA的Sobel边缘检测算法研究与实现

Research and Implementation of Sobel Edge Detection Algorithm Based on FPGA

针对某中小河流水文监测系统对水位实时监测的需求,提出利用现场可编程门阵列(FPGA)外接监控摄像头采集图像,结合Sobel边缘检测算法,完成系统设计并在FPGA上实现。实验结果表明:利用FPGA硬件系统较好地实现了Sobel边缘检测算法,呈现出的图像边缘信息也较为理想,能够满足监测系统的需求。

Aiming at the real-time monitoring of water level of a small or medium-sized river hydrologic moni- toring system, making use of FPGA external monitoring camera to collect images was implemented, including having sobel edge detection algorithm combined to complete system design and then to realize it on FPGA. The experimental results show that, the use of FPGA hardware system can better achieve sobel edge detection algo- rithm, and the image edge information presented is ideal to meet the needs of the monitoring system.
