OUTDOOR SEAMLESS POSITIONING METHOD AND APPARATUS THEREOF

摘要

PURPOSE: A method and a device for outdoor positioning are provided to obtain a successive positioning result with high reliability even in a situation hard to receive some satellite information by combining satellite navigation information and vision information. CONSTITUTION: A device for outdoor positioning installed on a target object comprises a satellite information acquisition unit(110), a structure image acquisition part(120), and a target object positioning unit(160). The satellite information acquisition unit acquires the coordinate information of satellites, a distance between the target object and the satellites, and measurement errors respectively. The structure image acquisition part acquires the image data of a structure around the target object and a distance between the target object and the structure by using a camera installed in the target object. The target object positioning unit acquires a position coordinate of the target object by using the coordinate information of satellites, the distance between the target object and the satellites, the measurement errors, the coordinate information of the structure, and the distance between the target object and the structure.
