Abstract

The invention discloses a hybrid registration method and system for target objects of a mobile augmented reality (MAR) system. The method comprises the following steps: (1) obtaining current geographical position information and target object information; (2) obtaining the target objects appeared in the current screen of mobile equipment and corresponding screen coordinate values of the target objects according to the current orientation and attitude data of the mobile equipment; (3) obtaining global motion parameters of the current mobile equipment according to the current continuous scene image of the mobile equipment; and (4) adjusting the screen coordinate value in corresponding registration information of each target object appeared in the current screen of the mobile equipment in real time according to the global motion parameters. The system comprises the mobile equipment, and the mobile equipment comprises a sensor unit, a sensor information processing unit, an image acquisition unit, a visual information processing unit and a hybrid registration unit. The hybrid registration method and system have the advantages of good real-time property, fast speed, high accuracy and wide application range.

Description
