| description | The invention relates to the technical field of defect detection, and particularly discloses a new energy automobile die casting crack defect detection system and a new energy automobile die casting crack defect detection method. The method comprises the following steps: extracting common discrimination features between a casting internal reference state image and a casting internal state image of a to-be-detected automobile die casting by adopting an image processing technology, and further erasing the common discrimination features from the internal state image features of the to-be-detected automobile die casting through a feature erasing mechanism; and on the basis of the feature reverse extraction mode, crack defect related features in the internal state image of the casting are excavated, so that whether the crack defect exists in the die casting or not is intelligently judged. Therefore, the accuracy and the stability of crack defect detection can be improved, so that the quality and the safety of the |
