description The invention discloses a method for positioning a binocular non-calibrated space, which comprises the following steps of: acquiring position data of a center point of a moving target by a background differencing method; by a camera imaging principle, calculating angle and directional data of the moving target in a scene relative to a shooting optical axis of a current analysis picture so as to obtain coordinates of a moving point and a shooting point; establishing a virtual coordinate system in the shooting scene and obtaining values of an angle a and an angle c between optical axes of cameras and an edge parallel to the longitudinal axis of the virtual coordinate system according to imaging target surfaces and focal length parameters of the cameras; and according to a distance BC between two cameras and the values of the angle a and the angle c, solving a coordinate value of the moving point E relative to a coordinate origin O of the virtual coordinate system and then according to the coordinates of the sho
