摘　　要：探讨并实现了适用于嵌入式系统的影像数据应用方案。在深入分析嵌入式系统与影像数据特性的基础上,提出了综合应用外存储模式和数据金字塔等方法解决嵌入式系统中应用影像数据的两大瓶颈——处理效率与数据量,并用某市0.6 m高分辨率影像数据作为实验数据,证明本方案的可行性与有效性;对其在提高外业调绘和土地利用现状更新调查等方面的效率做出了展望与评估。A program applicable to image data in embedded system was explored and realized. On the basis of a depth analysis of the features of embedded system and image data, solutions to the two problems of applying image data in embedded system, namely, treatment efficiency and the amount of data, with methods of external storage schema and digital pyramid were proposed. With a 0. 6-metre high-resolution image data as the experimental data, the program was proved practical and effective. Prospects and evaluation were made on the efficiency of the method to improve field identification and land use.
