This book starts from the development status of remote sensing image intelligent interpretation and application technology. It systematically introduces the main progress of this field and its application, focusing on remote sensing image intelligent quality improvement, intelligent expansion and sample augmentation, object detection, fine-grained target recognition, semantic segmentation, multimodal remote sensing image joint intelligent interpretation as well as intelligent interpretation and application platform. With the rapid development of large models and artificial intelligence technology, and supported by major projects such as the National Science and Technology Major Project of China High-resolution Earth Observation System, the authors and their team have made a series of research achievements in the field of intelligent interpretation and application technology of remote sensing images.
