Abstract
Embodiments disclose an augmented reality-based remote guidance method and apparatus, terminal, and storage medium. The method comprises the following steps: acquiring a two-dimensional video of a target scene, and sending the two-dimensional video to a remote terminal; if a guidance mode of the remote guidance is marking mode, acquiring two-dimensional pixel coordinates corresponding to a marked point in a marked image frame of the two-dimensional video at the remote terminal; determining current camera coordinates corresponding to the marked point, according to first three-dimensional coordinate estimation rules and the two-dimensional pixel coordinates, wherein the current camera coordinates are current three-dimensional space coordinates corresponding to the marked point in a camera coordinate system; and according to a presentation mode and the current camera coordinates rendering a three-dimensional virtual model corresponding to the marked point so as to display the three-dimensional virtual model in the target scene.
