Indoor-scene-oriented mobile augmented reality method

The invention discloses an indoor-scene-oriented mobile augmented reality method which comprises the following steps: extracting and optimizing a characteristic point, extracting and optimizing a characteristic line, screening an iterative characteristic line, constructing a mixed characteristic, matching the mixed characteristic, reversely calculating position parameters of a camera and drawing a virtual and reality combination, wherein extraction of the characteristic point and extraction of the characteristic line aim at acquiring a real-time image sequence of a scene through the camera of a mobile terminal; extraction and optimization of the characteristic point are respectively realized by taking a FAST angular point as a characteristic point and adopting Shi and Tomasi algorithms. The indoor-scene-oriented mobile augmented reality method can be well balanced between the stability and the calculation instantaneity of real-time motion tracking of the camera on a mobile platform, so that a stable and credible virtual and reality combination effect in the mobile augmented reality can be achieved.
