This disclosure provides a method, apparatus, and electronic device for detecting surface defects in steel plates. The method involves simultaneously acquiring multiple surface data points of the steel plate under test using different acquisition devices. For any given surface data point, a first modal feature tensor is extracted and normalized to obtain a second modal feature tensor. Based on a preset standard modal feature tensor and a first mapping relationship, first candidate defect regions are determined for all second modal feature tensors. Second candidate defect regions are selected from all first candidate defect regions. Third candidate defect regions are obtained based on the cosine similarity and fusion loss function of the second candidate defect regions. All third candidate defect regions are weighted and fused to obtain a fused defect region. The target defect is determined based on the candidate defect mask and a joint scoring function. This improves the accuracy of steel surface defect detection and can adapt to the detection needs of various complex industrial scenarios.
