在人工智能时代,遥感影像解译朝着自动化智能化方向发展,高质量的样本数据集是其核心.我国积累了海量优质的时空地理信息基础数据及衍生产品,是深度学习驱动的遥感影像智能解译样本的重要来源.盘活现有数据资源,可推动人工智能与遥感解译的应用深度与广度.本文基于现有数据资源,针对样本数据集区域受限、时效性不强、类型单一等问题,研究了面向深度学习的高分遥感影像智能解译样本库动态构建技术.首先,分析了要素提取、地表覆盖分类、变化检测方面的公开样本数据集的特点,提出业务驱动的样本应需生成-动态构建-智能应用思路;其次,研究了基于历史解译成果的样本自动生成、SAM大模型提示学习引导的样本清洗精化方法及实现过程;再次,设计了具有区域性、时序性、尺度性、多传感器、多类型的样本库,以及顾及空间-时间-地类关系的动态样本数据库架构,研究了样本数据集"量化-检索-组合"动态重构过程,实现时空样本的动态管理与多维检索;最后,开展了地表覆盖分类、要素提取、变化检测等智能解译应用,验证了本文研究思路及方法的可行性,以期推动基于已有基础数据的样本数据集的有效利用,以及样本构建-管理-应用及数据-模型-业务的互联互通,为高分遥感影像智能解译样本库构建与应用提供参考思路.
Dynamic construction of high-resolution remote sensing image sample datasets and intelligent interpretation applications
In the era of artificial intelligence,the interpretation of remote sensing images is moving towards automation and in-telligence.High-quality sample datasets are crucial for this development.A massive amount of high-quality spatio-temporal geospatial information and derived products has been accumulated in China,which serve as an important source for deep learn-ing-driven intelligent interpretation of remote sensing images.Leveraging existing data resources can promote the depth and breadth of artificial intelligence and remote sensing interpretation applications.Aiming at the limitations of existing sample datasets,such as regional restrictions,limited timeliness and sample types,this paper proposes a dynamic construction tech-nique for a high-resolution remote sensing image intelligent interpretation sample datasets based on existing data resources.Firstly,a business-driven framework for sample datasets demand generation,dynamic construction,and intelligent application is proposed based on the characteristics analysis of publicly available sample datasets for feature extraction,land cover classifi-cation,and change detection.Secondly,this research investigates methods and implementation processes for sample generation based on historical interpretation results,as well as sample refinement through SAM(segment anything model)large model prompt learning-guided cleaning.Furthermore,a sample dataset with regional,temporal,scale,multi-sensor,and multi-type features is designed,along with spatial-temporal-land cover relationships.The study explores the dynamic reconstruction process of sample dataset quantification-retrieval-combination,achieving dynamic management of spatiotemporal samples and multidimensional retrieval.Finally,intelligent interpretation applications such as land cover classification,feature extraction,and change detection are conducted to validate the feasibility of the proposed methods.The aim is to promote the effective utili-zation of sample datasets based on existing foundational data,as well as the interconnection of sample construction-manage-ment-application and data-model-business,providing reference ideas for the construction and application of high-resolution re-mote sensing image intelligent interpretation sample datasets.
