In the light of the news that the quality of medical solution influence the life safety accident frequently, the quality of medical product is paid more and more attention.Traditional liquid detection detection efficiency is low and the quality is not controllable.Aiming at the defects of the traditional manual detection, the detection system of the foreign body detection system is proposed, and the detection of the foreign body system based on the image sequence is proposed.Because of the single frame liquid image of the foreign particles of the particle size is small, only for the study of the object will be highly of the system equipment and algorithm.In this paper, the multiple images of the same spot in the mobile solution were collected and the frame difference method was carried out.After the processing of the stage, the background of the image is removed, and the foreign body is clearly observed.The object is then transformed into a foreign body trajectory after the foreign body is converted into a superposition, and the processing of the system is convenient for the system.In this paper, the similarities and differences between the traditional detection system and the detection system of the medical detection system were compared and analyzed, and the system was designed for the detection of foreign body.The image acquisition module introduces the camera selection, the source of several types and the system of the collection device map.The image preprocessing module analyzes the features of the CCD camera collection, and the appropriate image denoising method and the contrast enhancement method are adopted for the image processing.The foreign body detection module of the image first carries on the background operation to the single frame image after the preprocessing, and the area of the window is more than the specified value by the window area method.If there is no more than that, the single frame image trajectory is connected after the background, and the detection algorithm can determine whether the foreign particles exceed the scope of the pharmacopoeia.In the experiment of the system, the simulation of different algorithms is carried out,and the detection algorithm of area method and glass chip size is verified, and the accuracy of the algorithm is ensured.. And the frame difference method and highlight area method issimple, can improve the detection speed. In the paper, the highlight area of the image and the determination of the foreign particles are valuable for the research of foreign objects.
