  Abstract

This paper describes a new method for angle estimation using only a single camera, overcoming the limitations of previous indoor positioning methods that required sensors or infrastructure. By employing the principles of trigonometry. It demonstrates that angles can be estimated using just a landmark and a single camera. The study analyzes and compares methods of inferring angles using deep learning with those obtained through calculation, ultimately proving the efficiency of the algorithmic approach in angle estimation. This research describes a method for estimating the camera's position simply through calculations involving the camera and a landmark.
