Abstract	本发明公开了一种产品缺陷检测方法、装置、设备及存储介质，涉及自动检测技术领域，其中，一种产品缺陷检测方法包括：获取待检测产品图像；采用大律算法对待检测产品图像进行处理，得到第一图像分割结果；采用高斯混合模型算法对待检测产品图像进行处理，得到第二图像分割结果；采用后处理算法对第一图像分割结果和第二图像分割结果进行处理，得到检测结果。本发明能够大幅度地提高检测速度，适用于不同类型产品的表面缺陷检测，还能够减小不同光源、检测件摆放角度和阴影情况等外界因素对检测结果的影响，实现对生产线产品缺陷的准确检测。
Other Abstract	The invention discloses a product defect detection method, device and equipment and a storage medium, and relates to the technical field of automatic detection. The product defect detection method comprises the steps that an image of a to-be-detected product is acquired; processing the to-be-detected product image by adopting a large-law algorithm to obtain a first image segmentation result; processing the to-be-detected product image by adopting a Gaussian mixture model algorithm to obtain a second image segmentation result; and processing the first image segmentation result and the second image segmentation result by adopting a post-processing algorithm to obtain a detection result. The method can greatly improve the detection speed, is suitable for surface defect detection of differenttypes of products, can reduce the impact on a detection result from external factors such as different light sources, the placement angle of a detection part and the shadow condition, and achieves theaccurate detection of the defects of a production line product.
