Zusammenfassung: | The invention provides a nondestructive testing method for a solid rocket engine based on machine learning and computer vision. An input image is divided into a plurality of local images, and key learning is carried out on key parts, so that subsequent key feature extraction and preliminary judgment are facilitated. The problems of low artificial recognition rate, scattered image data, low data utilization rate and the like are solved. And efficient and rapid identification of engine nondestructive testing images is realized. The method can be used for engine nondestructive testing image recognition, and compared with an existing method, the recognition efficiency and accuracy are remarkably improved.
