Abstract

Human activities are closely related to geographic location. It is proposed to combine spatial location and mobile terminal pose sensor data with meeting the characteristics of real-time accuracy and flexibility in outdoor mobile augmented reality and to realize the virtual-real superposition through the transformation relationship between 3D model coordinate system, world coordinate system, camera coordinate system, image coordinate system, and pixel coordinate system. For the limitations of the vision-based registration method in outdoor scenes, this paper derives the transformation from spatial location data to screen coordinates in detail. It gives the solution and optimization of the transformation matrix and parameters.
