Abstract

The embodiment of the present invention relates to the field of computer vision, and discloses a positioning method, device, electronic equipment, and computer-readable storage medium. In the present invention, the positioning method includes: acquiring the current frame; determining the first area corresponding to the environment in the current frame and the second area corresponding to the target object in the current frame; determining the first area according to the image in the first area and the map of the current environment. Positioning result; wherein, the first positioning result indicates the relative pose relationship between itself and the current environment; according to the image in the second area and the three-dimensional model of the target object, determine the second positioning result; wherein, the second positioning result indicates itself and the target Relative pose relationship of objects. In this implementation, the electronic device can not only locate itself, but also locate and track a dynamic target object.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer vision, and in particular to a positioning method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] At present, when an augmented reality (Augmented Reality, AR) device locates itself in a static environment, it can use real-time positioning and mapping (Simultaneous Localization and Mapping, SLAM) technology. SLAM technology is quite mature, such as Google's software platform ARCore and ARKit, Apple's software platform. When an AR device needs to track a dynamic object, a model-based tracking algorithm can be used, which requires the three-dimensional information of the known object. When there is a CAD model of an existing dynamic object, or a 3D model of a dynamic object obtained by 3D reconstruction of the object through a calibration object, etc., the dynamic object can be tracked through the tracking algorithm and 3D information....
