摘　　要：提出了一种地理位置标注方法,基于照片拍摄时的相机位置和方位,通过坐标转换、前方交会快速获得照片拍摄目标的位置坐标,并与电子地图进行匹配,进行自动化地理位置标注。对于房屋调查、地名普查等大范围的多媒体信息采集工作,该方法方便快捷,具有一定的实际应用价值。This paper proposes a geo-location method based on the camera position and camera orientation during photo shooting. This method can quickly obtain the position of the object by the coordinate conversion and front intersection and then match it with the electronic map to automate geographic location. For the large-scale media collection work such as house survey and place name survey, this method is convenient and fast, and has certain practical application value.

关 键 词：地理位置标注 前方交会 坐标转换 地图匹配
