Image retrieval method and device, equipment and storage medium

The invention discloses an image retrieval method and device, equipment and a storage medium. The image retrieval method comprises the steps that a to-be-recognized remote sensing image is acquired; performing feature extraction on the remote sensing image based on a student network model to obtain feature data of the remote sensing image, the student network model being obtained by performing distillation training on a to-be-trained student network model based on a preset loss function and a pre-trained teacher network model; performing Hash processing on the feature data by using a Hash network in the student network model to obtain a Hash code of the remote sensing image; and retrieving a target reference image of the remote sensing image according to the hash code of the remote sensing image. 本申请公开了一种影像检索方法、装置、设备及存储介质，所述影像检索方法包括：获取待识别的遥感影像；基于学生网络模型对所述遥感影像进行特征提取，得到所述遥感影像的特征数据，其中，所述学生网络模型是基于预先设置的损失函数和预先训练的教师网络模型对待训练的学生网络模型进行蒸馏训练所得；利用所述学生网络模型中的哈希网络对所述特征数据进行哈希处理，得到所述遥感影像的哈希码；根据所述遥感影像的哈希码检索所述遥感影像的目标参考影像。
