Research on Acquisition and Retrieval Method of Locatable Image
摘要
Abstract
Image, especially the one with the location, is one of the most important sources for Geographic Information System(GIS). In this paper, an acquisition and retrieval method for the image with its taken location(here it is called the locatable image) is proposed. Expression model for content, metadata, location and description of the locatable image is defined, and all the attributes are acquired on Android device, and are saved in Exchangeable Image File(EXIF) format. The retrieval strategy based on the location and orientation is set up. The location is used to build grids for spatial index, while the orientation is for cluster index. The test result verifies the usability of the proposed method, which can quickly retrieve the image.关键词
