The invention discloses a matting model training method and device, a matting method and device, equipment and a storage medium, and the method comprises the steps: obtaining a first sample image with a label and a second sample image without a label, the first sample image and the second sample image comprise a target object, and the label is a matting result of the first sample image; and based on the first sample image and the second sample image, training the student model in a manner of combining knowledge distillation and semi-supervised learning of the multi-teacher model to obtain a matting model. In this way, the semantic representation and information extraction capability and generalization capability of the matting small model can be improved at the same time. 本申请公开了一种抠图模型的训练方法、抠图方法、装置、设备及存储介质，其中，该方法包括：获取带标签的第一样本图像和无标签的第二样本图像，第一样本图像和第二样本图像均包括目标对象，标签为第一样本图像的抠图结果；基于第一样本图像和第二样本图像，以联合多教师模型的知识蒸馏和半监督学习的方式对学生模型进行训练，得到抠图模型。通过上述方式，本申请能够同时提升抠图小模型的语义表征和信息提取能力、泛化能力。
