Abstract
An object positioning method includes obtaining an environment image collected by a target object through a camera of the target object and a camera parameter of collecting the environment image, determining candidate position information of the target object and a virtual camera parameter, rendering, based on a predetermined three-dimensional model, the candidate position information, and the virtual camera parameter, to generate a rendered image corresponding to the candidate position information, and determining position information of the target object based on the environment image, the rendered image, and the candidate position information. The virtual camera parameter and the camera parameter of the environmental image have a first correspondence. The three-dimensional model and a real space have a second correspondence.
