我们基于Xilinx PYNQ-Z2的强大图像处理能力，设计了一款低成本高性能，硬件可灵活配置，处理速度强大的远端现场微缺陷检测设备。Xilinx已内嵌入OpenCV 库，包含有50多项硬件优化的OpenCV 功能，包括Gausian、 Median、Bilateral、Harris corner、Canny edge、Canny edge detection等。我们首先对图像进行灰度处理，运用边缘检测算法对图像进行二次处理，找出图像边缘的突变点，针对标准产品图像对照滤波，即可以找出工业品的缺陷点。我们重点运用Canny等图像边缘算法及图像凸性检测函数处理出工业产品线图，综合运用比较其优缺点，进行腐蚀、膨胀、层次化和边缘处理的手段找出细小的缺陷，充分运用FPGA并行处理图像的强大计算能…
