Mold residue detection method and device

The invention relates to a mold residue detection method and device. The method comprises the steps of acquiring first image data corresponding to an image, which is collected by an industrial camera,in a mold cavity of an injection molding machine; preprocessing the first image data through a light compensation method and a position correction method to obtain preprocessed second image data; andtaking the second image data as input of a preset residue detection model, and determining whether residues are contained in the mold cavity or not according to a result output by the residue detection model. According to the invention, whether residues are contained in the preprocessed injection molding machine mold cavity or not can be recognized through the trained residue detection model, a manual recognition method which is low in production efficiency and high in recognition error rate is replaced, and the labor cost is saved while the recognition accuracy is improved. 本公开涉及一种模具残留物检测方法及装置，该方法包括：获取工业相机采集的注塑机模具腔体内
