Abstract

To solve the problem that the SIFT algorithm used in augmented reality algorithm can not accurately extract matching and the matching efficiency is low, a matching method combining SIFT algorithm, fast explicit diffusion FED and IMU is proposed. Firstly, the input image of the initial matching is processed by a nonlinear filtering operation using FED. Pre-integration is performed by the IMU inertial measurement unit to calculate the pose change of the camera between two frames of images. Then, the SIFT algorithm is adopted for image matching. Finally, the corresponding relationship between the virtual object coordinates registered on the screen and the real space coordinates is determined. With the help of IMU and the nonlinear image fuzzy processing, the proposed method has strong adaptability to images and can obtain the corresponding coordinates of real space in complex environments.
