Product detection method and detection device

The invention provides a product detection method. The method comprises the following steps: acquiring an image of a product; obtaining a three-dimensional model diagram of the product according to the information of the image; obtaining at least one section contour of the three-dimensional model graph; and comparing the section contour with a standard contour of a standard product, and judging that the product has defects. According to the detection method, the three-dimensional model diagram of the product is obtained, the at least one section contour of the three-dimensional model diagram is obtained, the obtained section contour is compared with the standard contour of the standard product, and whether the product has defects or not is judged, so that the product detection efficiency is improved. In addition, the invention provides a detection device at the same time. 本申请提出一种产品检测方法，该方法包括：获取所述产品的图像；根据所述图像的信息得到所述产品的立体模型图；获取所述立体模型图的至少一截面轮廓；将所述截面轮廓与标准产品的标准轮廓对比，判断所述产品具有缺陷。本申请通过获取产品的立体模型图，并获取该立体模型图的至少一截面轮廓，将获取的
