Method and device for detecting stain position of transparent medium

The invention relates to the technical field of stain detection, in particular to a method and device for detecting a stain position of a transparent medium. A light source is adopted on the outer side of the transparent medium to carry out stroboscopic and shooting on each transparent medium to be detected from multiple angles to obtain a plurality of shot images, and the stain forms on different shot images are highlighted to obtain the position information of the stains, so that the difficulty of determining that the stains are located on the inner side and the outer side of the transparent medium is greatly reduced, the detection precision is improved, the detection cost is reduced, and the labor cost is saved. Compared with an existing manual visual mode, the method has the advantages that the detection efficiency is high, and the speed is high. 本发明涉及污渍检测技术领域，涉及一种透明介质污渍位置检测方法及装置。本发明通过在透明介质外侧采用光源以多角度对每个待检测透明介质进行频闪并拍摄获得多个拍摄图像，将不同拍摄图像上的污渍形态突出显示，以此来污渍的位置信息，大大降低了确定污渍位于透明介质内外侧的难度，提高检测精度，降低了检测成本，节约了人工成本，同现有人工目视
