| 电子内窥镜作为现代医疗仪器中的重要设备，随着产量的不断增加，实现内窥镜信号线自动化焊接已成为一个必然趋势。为精确高效采集内窥镜镜头模组的焊点坐标，设计了一种基于现场可编程逻辑门阵列（field programmable gate array，FPGA）图像处理的内窥镜焊点检测系统。整个系统以OV5640作为图像采集器件对目标板的图像数据进行采集，通过Verilog HDL硬件描述语言进行图像处理，实现焊点检测和瑕疵判别算法的设计。硬件测试结果表明，该系统能实时采集焊点坐标并检测焊点之间的瑕疵，采集到的焊点坐标最大误差小于0.1 mm，检测精度高，实时性强，具有广泛的应用前景。 |

| Electronic endoscope is an important equipment in the modern medical instruments. With the increase of production, automatic welding of endoscope signal line has become an inevitable trend. A field programmable gate array (FPGA) image processing system for welding spot detection of endoscope lens module was designed to accurately and efficiently capture the welding spot coordinates of endoscope lens module. In the whole system, OV5640 is used as the image acquisition device to collect the image data of the target board. Image processing is carried out by Verilog HDL hardware description language for welding spot detection and defect discrimination algorithm. The hardware test results show that the system can collect the coordinates of solder joints in real time and detect the defects between solder joints. The maximum error of the collected coordinates is less than 0.1mm. the detection accuracy is high, and the real-time performance is high. The system has a wide application prospect. |
