Auxiliary reconnaissance target positioning method based on image analysis

The invention belongs to the technical field of auxiliary reconnaissance positioning, and particularly relates to an auxiliary reconnaissance target positioning method based on image analysis. Comprising the following steps: storing a frame of image in which a striking target and an auxiliary reconnaissance target appear in a view field at the same time, and recording coordinates and attitude angles of an aircraft in a geographic coordinate system, a camera frame angle and a misalignment angle; calculating the distance between the striking target and the aircraft; calculating a pitching sight angle; calculating coordinates of the auxiliary reconnaissance target in a camera coordinate system; the coordinate of the auxiliary reconnaissance target in the camera coordinate system is calculated through coordinate transformation, and the coordinate of the auxiliary reconnaissance target in the geographic coordinate system can be obtained by combining the current coordinate information of the aircraft.
