The invention discloses a method for identifying a space target by using a mobile terminal and a geographic three-dimensional scene, which comprises the following steps of: creating a three-dimensional information model or a three-dimensional map for a region, creating a three-dimensional model for a geographic object in the region, and adding related attributes such as ID (Identity), name and category; constructing a geographic three-dimensional scene by adopting a three-dimensional GIS framework; sighting a target object through a camera of the terminal equipment to obtain data; transmitting the group of data into a three-dimensional scene, and setting a virtual camera in the scene into corresponding parameters, namely realizing the consistency of positions, heights and postures of an actual camera and a scene camera; a three-dimensional model in a scene is picked up by using a ray intersection function of a three-dimensional scene camera, and attributes of the three-dimensional model are obtained.
