Claim 4:
5. An aerial survey apparatus capable of eliminating redundant aerial photos, comprising a judging module and an aerial camera control module; wherein the judging module is configured to judge whether there is an intersection between ground projection data of aerial photos at a photographing coordinate point and known data of a target region; and the aerial camera control module is configured to keep aerial photography data of the photographing coordinate point or perform aerial photography at the photographing coordinate point when there is an intersection between the ground projection data and the known data, and eliminate the aerial photography data of the photographing coordinate point or not perform the aerial photography at the photographing coordinate point when there is no intersection between the ground projection data and the known data,
wherein the ground projection data of the aerial photos at the photographing coordinate point is obtained according to coordinate information and attitude information of an aircraft or an aerial camera at the photographing coordinate point, and parameter information of the aerial camera, and
wherein the photographing coordinate point is a point in space determined by longitude, latitude and altitude data; the attitude information comprises angular velocity information and acceleration information; the coordinate information comprises longitude, latitude and altitude information; the parameter information comprises geometric parameter information and optical parameter information of the aerial camera; and the known data of the target region is a vector data, comprising keyhole markup language (KML) data or shapefile (SHP) data.
