Repositioning method, apparatus and device for camera pose tracking process, and storage medium

Abstract

The invention discloses a repositioning method, apparatus and device for a camera pose tracking process, and a storage medium, and belongs to the field of augmented reality. The method comprises the steps that when a target image meets a repositioning condition, a front-end program is used for switching the target image into an (i+1)th mark image, and sends the target image to a back-end program;the front-end program obtains a current image collected after the target image, and performs feature point tracking on the current image relative to the target image to obtain a first pose parameter;the back-end program conducts re-positioning on the target image to obtain a second pose parameter, and sends the second pose parameter to the front-end program; and the front-end program calculates acurrent pose parameter of the current image according to the first pose parameter and the second pose parameter. According to the repositioning method, apparatus and device, even if the time for a re-positioning result of the target image by the back-end program is relatively long, a positioning result of the current image also can be corrected, so that a relatively good repositioning effect is guaranteed.

Description

technical field [0001] The embodiments of the present application relate to the field of augmented reality technology, and in particular to a method, device, device, and storage medium for relocating a camera pose tracking process. Background technique [0002] In the field of AR (Augmented Reality, augmented display), the subject equipped with the camera needs to track the movement posture of the camera in the real environment during the movement process without prior information of the environment. [0003] In the related art, the movement process of the camera is divided into at least two tracking processes for tracking, and each tracking process corresponds to a respective marker image (Anchor). Usually, the first frame of image captured by the camera is used as the first marked image. When the camera subsequently captures the current image, the device tracks the common feature points between the current image and the first marked image. According to the current image an...
