Spatial image information system and method for supporting high-efficiency memory and searching spatial image

公开了一种在关系型数据库中快速高效地存储、以及检索和管理空间图像的空间图像信息方法和系统，该空间图像是由全球定位系统(GPS)、惯性导航系统(INS)和图像获取装置(即CCD照相机)的组合系统所获取的。将空间图像与外方位及内方位结合起来，以便计算出指定空间坐标信息。该空间图像信息系统包含：用于在关系型数据库中高效地存储一系列静止空间图像序列，外方位和内方位的部件；用于在维护与所存储的静止空间图像序列的关系时，存储由用户认定为同一对象的空间信息的部件；用于从静止空间图像序列中高效地检索满足特定空间信息操作的图像的部件；以及用于外部系统的接口部件。 Disclosed is a spatial image information method and system for rapid and efficient storage in a relation type database and retrieval and management of spatial images acquired by a combined system of a global positioning system (GPS), an inertial navigation system (INS), and an image acquisition device (i.e., CCD camera). The spatial image acquired by the GPS/INS/CCD camera combined system is combined with an exterior orientation composed of a camera position (x,y,z), accelerated velocity, slope and direction at the moment the image is acquired and an interior orientation acquired by a camera calibration, so that calculation of a specified spatial coordinate information becomes possible. The spatial image information system includes a section for efficiently storing a chain of still spatial image sequences acquired by the GPS/INS/CCD camera combined system, the exterior orientation, and the interior orientation in the relation type database, a section for storing spatial information recognized as the same object by a user as maintaining the relationship with the stored still spatial image sequences, a section for efficiently retrieving images that satisfy a certain spatial information operation from the still spatial image sequences, and an interface section for external systems.
