  "textContent": "The present invention discloses a positioning method and apparatus. The method includes: acquiring a first image captured by an optical device, where the first image includes an observation object and a plurality of predetermined objects, and the predetermined objects are objects with known geographic coordinates; selecting a first predetermined object from the predetermined objects based on the first image; acquiring a second image, where the first predetermined object is located in a center of the second image; determining a first attitude angle of the optical device based on the first predetermined object in the second image and measurement data captured by an inertial navigation system; modifying the first attitude angle based on a positional relationship between the observation object and the first predetermined object in the second image, to obtain a second attitude angle; and calculating geographic coordinates of the observation object based on the second attitude angle. According to the present invention, a prior-art technical problem that costs of accurately locating an observation object are high is resolved.",
