| 针对目前国内药品检测数粒机大多是多通道数粒机，存在稳定性差、检测精度低等缺陷，课题组提出了基于FPGA的平板式数粒机检测系统。采用现场可编程门阵列（FPGA）作为控制系统的核心，对面阵图像传感器进行参数配置、图像数据采集，并对原始图像进行增强预处理。再由FPGA运用Canny算法获取图像采集单元的药粒目标轮廓信息，运用质心法获取质心位置坐标，采用检测线目标位置预测计数方法实现药品的高速在线检测计数。实验结果表明，基于FPGA的面阵图像传感器数粒机系统可以实现高速度、高精度的在线计数。 |

| At present, domestic drug testing counting machines are mostly multi channel counting machines, which have the disadvantages of poor stability and low detection accuracy. Aflat panel counting machine testing system design based on FPGA was proposed by the research group. The counting machine adopted FPGA as the core of the control system. It configured the area array image sensor parameters, collected image data, and performs enhanced preprocessing on the original image. Then FPGA used Canny algorithm to obtain the target information of the medicine particles in the image acquisition unit, and used the centroid method to obtain the coordinates of the centroid position, and used the detection line target position prediction counting method to realize the high speed online detection and counting of medicines. The experimental results show that the FPGA based area array image sensor counting machine system can achieve high speed and high precision online counting. |
