摘要
The present disclosure provides a method comprising: acquiring a plurality of images of a plurality of scenes in advance, and performing feature extraction on the plurality of images respectively, to obtain a corresponding plurality of feature point sets; performing pairwise feature matching on the plurality of images, generating a corresponding eigen matrix according to the pairwise feature matching, and performing noise processing on the eigen matrix; performing 3D reconstruction according to the feature matching and the noise-processed eigen matrix and based on a ray model, to generate a 3D feature point cloud and a reconstructed camera pose set; acquiring a query image, and performing feature extraction on the query image to obtain a corresponding 2D feature point set; and performing image positioning according to the 2D feature point set, the 3D feature point cloud and the reconstructed camera pose set and based on a positioning attitude image optimization framework.
