Casting defect detection method and device, electronic equipment and storage medium

The embodiment of the invention provides a casting defect detection method and device, electronic equipment and a storage medium. The method is applied to the technical field of data processing and comprises the steps of collecting an X-ray image of a casting to be detected; the backbone network performs feature extraction on the X-ray image of the casting to be detected to obtain a first feature map, a second feature map and a third feature map; the multi-scale feature fusion module fuses the third feature map to obtain a first fused feature map; the first channel attention module adjusts the first fusion feature map to obtain an encoder output feature map; a second channel attention module adjusts the first feature map, a third channel attention module adjusts the second feature map, and a fourth feature map and a fifth feature map are obtained respectively; obtaining a second fusion feature map according to the encoder output feature map, the fourth feature map and the fifth feature map; and feature select
