A photovoltaic assembly defect detection method and apparatus, a classifier training method, a terminal device, and a non-transitory storage medium. Said detection method comprises: detecting a salient-region of a target image to obtain positional information of at least one salient region; obtaining at least one input image according to the positional information of the at least one salient region; and inputting the at least one input image into a classifier, so that the classifier outputs class information of the at least one salient region. The detection method can improve the efficiency of photovoltaic assembly defect detection, thereby realizing real-time detection.
