Description
Summary:Aiming to the development tools for Augmented Reality,ARtoolkit,and to obtain a particular coding region of interest,Marker Cards and the corner feature are used to calculate the position of the camera. But the accuracy rate is low,and viewing angle and scenes are stirctly limited. Based on the simultaneous localization and mapping and random sample consensus algorithm,this paper studies how to use instant space location algorithm to accurately calculate the spatial coordinates of camera external parameters and image sequence ORB( oriented fast and rotated brief) feature point set. Then random sampling and poster frame are used to obtain two dimensional coordinates of region of interest to locate. For these restrictions,a new method is proposed in this paper by integrating SLAM and RANSAC to obtain a particular coding region of interest and calculate the position of the camera. Experiments show that the method can solve the limitation of viewing angle and scenes and improve the accuracy of calculate the position of the camera. The degree of improvement is up to 90%,providing a strong guarantee render 3D augmented reality
