Abstract

The invention discloses a satellite picture defect-based positioning, identifying and classifying method. The method comprises the following steps of: (1) a preprocessing step: enhancing the characteristics of noisy points and noisy lines of original pictures, and segmenting all the enhanced pictures into a training data set and a test data set; (2) a model training step: feeding the training dataset into a deep learning neural network, carrying out iterative training, evaluating the effect of the trained model by using the test data set to obtain an optimal model; and (3) a model deploying step: reasoning an updated image by using the optimal model, and realizing the positioning, identification and classification of defects in the new image in real time. According to the method, end-to-end learning is realized, image screening speed and precision are improved, and an automatic, efficient and accurate solution is provided for the problem of low production efficiency of manual image screening which puzzles people in the past.

Description

Technical field [0001] The invention relates to the technical field of artificial intelligence computer vision, in particular to a method for positioning, identifying and classifying defects based on satellite images. Background technique [0002] Image recognition and classification is the cornerstone of the intersection of image understanding and artificial intelligence, and it is also the most challenging task. According to the paper review "Deep Learning for Generic Object Detection: A Survey" published in 2018, deep neural network is the learning of feature expression Provide strong support, especially for image recognition and classification tasks, and are driving major national strategic policies related to national economy and people's livelihood such as robot vision, e-commerce, autonomous driving, human-computer interaction, content-based image retrieval, intelligent video surveillance and augmented reality Sinking and landing. [0003] At present, the screening and diag...
