Children nasal cavity tissue identification method and device based on fiber nasopharyngeal endoscope video

The invention provides a child nasal cavity tissue identification method and device based on a fiber nasopharyngoscope video, and the method comprises the steps: obtaining the fiber nasopharyngoscope video of a single object, and selecting a plurality of key frames and optimal frames from the fiber nasopharyngoscope video; generating a large-size image based on the key frame; inputting the large-size image and the optimal frame into a pre-trained segmentation identification model to obtain a corresponding segmentation result and an identification result; and based on the segmentation result and the identification result, obtaining an adenoid judgment result of the nasal cavity tissue. According to the method, the key frame and the optimal frame of the fiber nasopharyngeal endoscope video are acquired, and the large-size image is generated, so that the relevance between the key frame and the optimal frame is improved, and the accuracy of segmentation recognition and the accuracy of adenoid judgment are further
