Problems solved by technology

[0003] At present, the ORB algorithm is usually used to search for matching keyframes for relocation to determine the current pose of the device. This solution only uses the matching information of the image and ignores the spatial connection, resulting in low relocation accuracy.

Abstract

The invention discloses a repositioning method and electronic equipment, and the method comprises the steps: determining the initial posture information of a first image through the related information of a second image in a first image library, and determining the image information of a plurality of correlated third images based on the information of at least one first 3D feature point of the second image, therefore, the initial attitude information of the first image is adjusted, the accuracy of the attitude information of the first image is improved, calculation is conducted based on the incidence relationship of the multiple images in the repositioning process, and the accuracy of the attitude information obtained through calculation is higher.

Description

technical field [0001] The present application relates to the technical field of virtual reality, in particular to a relocation method and electronic equipment. Background technique [0002] When a user uses an AR device, usually the global map accuracy does not have an obvious impact on the user experience, but is more sensitive to the pose of the virtual object relative to the current local environment. [0003] At present, the ORB algorithm is usually used to search for matching keyframes for relocation to determine the current pose of the device. This solution only uses the matching information of the image and ignores the spatial connection, resulting in low relocation accuracy. Contents of the invention [0004] In view of this, the present application provides a relocation method and electronic equipment, and its specific scheme is as follows: [0005] A relocation method comprising: [0006] Determining a second image in the first gallery based on the first image...
