高分辨率遥感影像阴影检测与补偿系统的设计与实现
Design and development of the shadow detection and compensation system for high-resolution remote sensing images
摘要
Abstract
Shadow detection and compensation involve such problems as the uncertainty of remote sensing images, the complexity of algorithm and the low degree of automatic extraction. In view of this situation, the authors have designed an integrated experimental system based on the algorithm built for high-resolution remote sensing image shadow detection and compensation on the ArcGIS Engine platform. The system also utilizes Matlab and GDAL. Some key technologies such as data block reading, 2% linear stretch and DLL are used in the shadow detection and compensation system implementation, which solves some problems such as reading large quantities of data, uncertainty of image, and extensibility of the system. The system achieves the integration and optimization of the system, and improves the operating efficiency. Experimental results show that the system performs higher precision and efficiency in shadow detection and compensation for high-resolution remote sensing images such as QuickBird and ZY-3. Therefore, the system can be used for batch processing of remote sensing image data.关键词
