Abstract: Using a single camera localization, it needs to set the geometric constraint of the characteristic points between the images and the actual object, and set up the mathematical equations, in order to get the closed solution of object in the camera coordinate system. The three-dimensional position of the object in the world coordinates system is obtained by solving the equation. A single camera positioning technology to position the indoor airship in science and technology museum is proposed, and the location problem of the science and technology museum indoor airship autonomous navigation is solved. Experiment shows that this method is simple and practicable, and can be used in engineering application. It has high practical value and theoretical significance.
