基于特征组合的无人机影像城市地表要素提取
摘要
Abstract
Urban surface elements are the basic components of urban management and planning,and accurate acquisition of their information is of great significance for urban planning and social and economic analysis.Based on some drone image data in Jinzhai County,this paper uses an object-oriented classification method to study the extraction of urban surface elements,and explores the impact of the number of features and different feature combinations on classification results.The results show that,the selection of features is fully considered,and the more the number of features is selected,the higher the accuracy of the result;in urban feature extraction,the Bayesian model has higher accuracy than the KNN model,with the overall accuracy reaching 84%,and the Kappa coefficient is 0.78.关键词
